Some old stuff. 29 Nov 2011. Jet Stunt Extreme Show at Seaworld, Gold Coast, Queensland. K5 + DA 55-300/F4-5.8 @300mm FL. All 1/1000s, f/6.3, ISO160. I was at quite a distance (across the lake) so the cropped frames are approx. 1/4 of the original frame area. This lens is a bit soft at 300mm compared to the DA* 60-250 at 250mm, but I wanted a light compact lens to carry around all day. SilkyPix Developer Pro 6 + PSP X7.

SilkyPix reduces sharpening when saving to JPEG format

I don't normally shoot DNG+. But here are some development comparisons. I've got SilkyPix Studio Developer Pro v6. The US Marines were visiting Brisbane and I photographed this vessel from across the river using a K3 + DA*60-250/F4 @ 250mm FL, 1/320s, f/4, ISO640. 21 Jun 2015 17:00:28. Sunset was 17:01 on that day so I was shooting in lowish light.

"Natural Fine" sharpening preset. Comparing the JPEG development sharpening settings of 31%, 0.2px radius, 8Lv threshold (yours) to 70%, 0.6, 1 (SP's "Original Image" preset).




(All comparisons are at 100% zoom level. I suggest you open these comparison images of approx. 1680x1000 in a new browser tab, and zoom in to 100%, if necessary.)

At 100%, you can see the noise here. I'll compare the "campaign ribbons" at the top LH. I think you could have used more JPEG development sharpening here.


Next, the "Natural Fine", 100%,0.6pc,1LV version vs "No Sharpening" (in SP), saving as 16-bit TIFF (no output sharpening) for further processing in PSP X7. In PSP, with the "Focus Magic" (deconvolution sharpening) plugin set to a radius of 4px, and PSP USM sharpening of 70%, 0.6, 1. (I often use this processing combo, and let FM chose a suitable radius based on its analysis of the initial sharpness of that part of an image.)



Even though devolution sharpening usually increases the noise, the overall result shows less noise here, and the sharpness is still acceptable.


Finally, no sharping in SP -> TIF to PSP, no FM, just USM of 200%,0.6,1 vs the same but including FM 4px and USM of 70%, 0.6,1.



You can see that the higher USM was not sufficient compared to the difference FM made here.

Finally, here's the full image. (I've only worked on the sharpening, not the colouration or TRC.) No sharpening in SP. In PSP, USM 200%,0.6,1, resized to 562x800, USM again of 100%,1,1.

Thanks for describing your processing. We're all here to learn something new. And the day that stops - well life will have lost its interest.

How do you think they get that exaggerated motion-blur effect you often see in commerical images?

Typical of Brisbane. Brisbane has only half the cloud cover of say London. From World Weather Online | World Weather | Weather Forecast



Queensland, the Australian State of which Brisbane is the capital city, has the official title of "The Sunshine State" to differentiate it from the other states. Queensland has the highest rate of melanoma in the world because so many people here are UK & Celtic descendants. From Melanoma facts and statistics - Melanoma Institute Australia

Australia and New Zealand have the highest melanoma rates in the world with Queensland incidence rate of 71 cases per 100,000 people (for the years 2009-2013), vastly exceeding rates in all other jurisdictions nationally and internationally.

The winner is D1N0. I like his idea of combining both images. It's a pity I didn't have a 3rd image, either between the other 2, or to the right of them - a 3-runner sequence would have been cool.
The colours are acceptable, but still a bit wonky according to my memory, but remembrance of colours is unreliable.
Notice the section inside the yellow rectangle in the top LH corner. This section isn't in either image and has been fabricated. Since it's in the background, it's not that significant and you probably wouldn't notice the deception during a casual inspection.

D1N0, would you like to explain what processing steps you performed?




Two honourable mentions. The shadowed side of the runner and the reflection off the track made the colours difficult. Lighten/correct this and it tends to make the track too pale. But taking the runner out of the background means than the runner can be rendered more satisfactorily - perhaps it's just not having the track colour appearing around him.

Todd can you explain how you produced this effect? It's a pity that there's not more motion blur apparent for the left hand and for the head.That would have intensified the impression of speed.

I'm enjoying the contributions so far. When the contest ends I'll be asking a few questions on how some contributors got their result.

I've posted part of another image from the start of this race in the General Talk forums. I've got an anatomy query about a prominent inner-thigh muscle in the image. So it's not a photography-related, but it has got me curious. I tried to look it up myself, but the muscles in the human thigh look complex in the diagrams and I'm not sure that I've identified the correct one. If you've got any medical knowledge talk a look.

I've currently got a Post-Processing challenge running. (PP Challenge #271 - The Relay Runner - PentaxForums.com). From the same relay race start as featured in the challenge here's part of another image:




I don't normally keep this type of running image as I prefer shots with the arms raised high. But I noticed that an inner thigh muscle was quite noticeable in the shot. (I don't think it's a trick of the light.) I'm hoping that someone who knows anatomy can confirm that this is the Adductor Longus muscle?

Hello and welcome to the Pentax Forums Post-Processing Challenge!

For those that are new around here the challenge is based on a person being selected from the previous challenge to provide a full size photo (typically in both RAW & jpeg). The host provides any details and expectations on the challenge like what they are looking for, total number of submission per person taking the challenge or maybe a 'just go for it'.

Usually the challenges run for about a week or so with timings aimed to be flexible as we all have lives outside the forums. At the end of the challenge the host reviews the submissions and chooses their favourite. That person then becomes the next host for the following challenge. Some hosts also provide PP feedback too but this is an individual thing so it's welcome but not a must for the host.

Hopefully you take the opportunity to join us and see how many interpretations can be made from the one image.

Some details about this image: From Little Athletics Queensland 2013 South-East Queensland Regional Relays. This was the start of the U13 Boys Distance Relay race. There are 4 different relay legs: 200m, 200m, 400m, 800m. There were 2 U12 runners, including my son, the 1st runner (normally an U12 400m runner), "running up" in this older age bracket in the two 200m legs to make up a 4-boy team. (They set a new LA SEQ U13 record in this event.)

K-5, DA*60-250/F4 @ 80mm FL, 1/1000s, f/6.3, ISO160, -1 EVcomp.

There are two shots. You can use either. The 2nd shot is either 4 or 6 steps later than the first. (The EXiF shows 1s later.) Unfortunately, this was a big meet and the trackside was crowded so I couldn't position myself any further forward in front of the runner or with the sun behind me.

The embedded JPEGs (no processing) and the PEFs:



https://dl.dropbox.com/s/n11pngxk7y8hju1/K5_89781.PEF




https://dl.dropbox.com/s/vr6m8kve2w7rzbo/K5_89784.PEF


The red tartan track material reflects coloured light up onto the runner. It confused the AWB. I couldn't get a decent colour rendition when developing the PEFs so I B&W them. Perhaps you can do better.

iheiramo, I like the composition of your wind-surfing shot. The colour of the sail amidst the otherwise drab colours makes your subject stand out.

And the extra-low angle works well here.

BTW, I tried a portrait-orientation crop of this shot. Full height, with the sail a bit in from LH edge and the spray almost to the RH edge of the crop. I think that works well too.

I've shot junior athletics and soccer in the rain. I like the extra drama and determination that you see in heavy rain. And the splashing around. I use the DA* 60-250/F4. It's OK for about 60-90 mins but eventually the changes in internal volume from constant zooming in and out seems to draw moist air into the lens and it fogs up. An internal focus (IF) zoom lens would probably be better.

K-5 for sports-photography - Page 40 - PentaxForums.com


If shooting a subject some distance away in heavy rain, the amount of rain greatly decreases the contrast. (I think it's more than just the heavily overcast conditions.) I find it worthwhile to increase the Contrast/raise the Black Point when you develop the images.

Excel 2003 LV (Light Value) Calculator

ExifTool (ExifTool by Phil Harvey), written by Phil Harvey, shows 2 LV entries in Pentax image files:

Light Value: computed by Exiftool using LV = 2 * log2(Aperture) - log2(ShutterSpeed) - log2(ISO/100)
Effective LV: in the MakerNotes section.

This is different from APEX, which uses ISO3.125 (Sv 0) as the Speed Value reference, whereas the formula above uses ISO100 (Sv 5).

Probably because LV = EV100 has gained some currency. Lv & Bv are being used interchangeably too.
See: Light value - Wikipedia

Doug Kerr mentions this trend on p.10 of http://dougkerr.net/Pumpkin/articles/APEX.pdf
Scene brightness in Ev?

We often see, especially in camera specifications, a factor that seems
to be scene luminance (brightness) described in terms of an Ev
number. Such a factor might be, for example, the lowest scene
luminance for which the exposure metering system of the camera is
able to function reliably.

This usage is unfortunate and technically inappropriate, as Ev is a
measure of exposure, not luminance. There is a perfectly good APEX
quantity for luminance: Bv. I suspect the motive for the practice is
that many photographic enthusiasts have heard of Ev but not Bv.

Of course, if we know the Ev that a camera’s metering system
recommends for a scene, we can in fact equate that to scene
luminance if we also know the ISO sensitivity (Sv) in effect.

It turns out that, when a manufacturer states some critical scene
luminance in terms of “Ev”, and nothing to the contrary is stated, it is
most often based on the assumption that the ISO sensitivity is
ISO 100 (Sv 5). (Canon, for example, so states explicitly.) In other
words, the luminance being described is that which, if the ISO
sensitivity of the camera were ISO 100, would lead to the camera
arranging for an exposure of the stated Ev.

The relationship between this irregular description of scene luminance
in “Ev” and the description of that luminance in the proper value, BV,
is as follows:

Bv=Ev’–5

where Ev’ is the so-called “Ev” used to describe the luminance.

I discourage this usage.


It looks like common usage is winning out.

The Exposure Value table (Table 2) "for various lighting conditions" below uses EV100 as an apparent surrogate for LV, presumably because ISO100 is of more relevance to normal photography than ISO3.125.

Exposure value - Wikipedia

Since the "Effective LV" tag in the MakerNotes section is showing maker-specific info, Pentax is also chosen to use ISO100 as their sensitivity reference value for LV.

My LV Calculator also uses ISO100 as the ISO stops reference, but compared to the formula in Exiftool, I do the log2 conversion once overall, rather then separately on each term. The one log2 conversion should reduce rounding errors.

The sensitivity of an image sensor can be defined in at least two different ways:
  1. Quantum Efficiency (QE) is how efficiently photons are being converted to photo-electrons. To increase this you need to either increase the Fill-factor, by adding or improving the microlenses above every sensel or use a more transmittive Colour Filter Array or remove the CFA completely and shoot monochrome. By using high voltage it is possible to use photon-multiplication and avalanche-mode techniques to increase the number of photo-electrons released by a photon, but such methods are too complex and costly for consumer DSLRs and are usually reserved for specialised surveillance and military usage.

  2. Conversion Gain (CG) is how large an output voltage is produced per photo-electron. Since the number of photons captured is still the same, the shot noise SNR is still the same. But a high CG helps to overwhelm the read noise (RN) being contributed by the output Source Follower (SF) transistor associated with each sensel. Sensor design usually involves trade-offs. High CG (HCG) improves the noise performance at low Light levels (LL). But HCG means that less photons can be captured before either the FWC of the sensel is reached or the ADC runs out of digits. When dealing with LL, there aren't that many photons so HCG is desirable. But in good light, noise is not a problem, but a large FWC leads to a better Dynamic Range (DR), hence the desirability of LCG. In most sensors, the chosen CG was therefore a compromise.


Today we have the luxury of Dual CG sensels in many Sony-manufactured sensors. This technology became available to Sony through an IP swap with Micron/Aptina (now ON Semi). See this white paper:

http://www.photonstophotos.net/Aptina/DR-Pix_WhitePaper.pdf


It's pretty easy to see which sensors are using Dual-CG tech: just look for the discontinuity in the mid-ISO region, in an Input-Referenced RN vs ISO chart (from http://www.photonstophotos.net/Charts/RN_e.htm):



(A discontinuity at High-ISO will be raw-level NR kicking in.)

So now we can switch the "sensitivity" between LCG & HCG (Dual CG) when we alter ISO in some cameras.





But Dual CG may not be the final improvement in this area. A very interesting paper has appeared at the 2017 IISS Workshop about "An 87dB Single Exposure Dynamic Range CMOS Image Sensor with a 3.0μm Triple Conversion Gain Pixel":

http://www.imagesensors.org/Past%20Workshops/2017%20Workshop/2017%20Papers/R29.pdf

Fig.5's caption in that paper mentions: In the LPG mode, photodiode saturation occurs before ADC saturation.

When the sensel saturates before the ADC, you get a "soft-limiter" knee whereas, if the ADC saturates first, you get a 'hard-limiter" knee. Compare Figs. 1 & 2 here:

How to Measure Full Well Capacity (1) Harvest Imaging Blog

The gain is usually set in DSLRs so that the ADC saturates before the sensel.




Anyone who has ever done an "Introduction to Semiconductors" has heard of electrons & holes (an atom with a missing electron in the valency band/outer shell, aka a positive ion).

See: What is hole? - Definition from WhatIs.com

When a photon is converted in a sensor, it liberates a negatively-charged electron (e-) within the pinned photo-diode (PPD), leaving behind a positively-charged hole (h+). The e-, accumulated in the PPD during the duration of the exposure, are then transferred to the floating diffusion (FD). The h+ are not used and are drained away into the substrate. This is because electrons are typically the primary charge carriers in most semiconductor devices. Quoting from Electron hole - Wikipedia
In most semiconductors, the effective mass of a hole is much larger than that of an electron. This results in lower mobility for holes under the influence of an electric field and this may slow down the speed of the electronic device made of that semiconductor. This is one major reason for adopting electrons as the primary charge carriers, whenever possible in semiconductor devices, rather than holes. Also, why NMOS logic is faster than PMOS logic.
However, in this innovative sensor design, both e- & h+ are collected:

Sensors | Free Full-Text | A 750 K Photocharge Linear Full Well in a 3.2 ?m HDR Pixel with Complementary Carrier Collection





BTW, Section 1.4. of the article above discusses dual-PD pixels to improve DR. An example of this is the 2006 FujiFilm FinePix S5 Pro (FinePix S5 Pro - Wikipedia) which used a Super CCD SR sensor (Super CCD - Wikipedia). (Note: Some Canon sensors also use dual-PPD pixels, but this is for AF reasons, not for DR improvement.) Compare the DR & SNR 18% of the S5 Pro against the 2005 D200, with its conventional CCD sensor, and with a CMOS sensor of the modern era, the break-through Sony IMX071, as used in the 2010 Pentax K-5:

Pentax K-5 vs Fujifilm FinePix S5 Pro vs Nikon D200

The differences in SNR 18% are due to QE, which is affected mainly by fill-factor and CFA filter transmissivity. The article mentions that dual-pixel designs, through a lower fill-factor, lose at least 5% QE compared to a conventional design.

The DR of the S5 Pro was exceptional in its day, and still impressive today until you exceed ISO800. Above this ISO, only the output from the larger pixel in the Super CD SR sensor is used, so it has similar performance to a conventional sensor. As I understand it, the reason the small pixel is switched off above ISO800 is because, as ISO increases, you are dealing with smaller and smaller exposures. (The reason for using higher ISOs, in the first place, is to brighten dimmer & dimmer exposures.) But the small pixel is relatively noisy, so continuing to include its RN contribution to the Total RN becomes untenable as the wanted signal level decreases.

I'm a long-time Vegas Pro user (v6, v7, v8, v12). I have not bothered updating since then, as any new features were not worth the upgrade price, IMHO.

However Humble Bundle, a legit charity source of bundled older software (Humble Bundle - Wikipedia), which previously had a wonderful bundle which offered the complete O'Rielly & Associates Programming and Technology Library in PDF format for $20 USD, has a bundle where you can get Vegas Pro 14 Edit (as well as other Magix stuff) for $20 USD. I purchased it today and registered it. It works well.

The extras & 3rd-Party plugins missing in the Vegas Pro 14 Edit version, which are included in the Vegas Pro 14 full version, are:
  • DVD Architect 7

  • NewBlue VegasPro Complete

  • ProDAD Mercalli 4

While I would have liked to have gotten Mercalli (a stabilisation plugin), Vegas itself is all there. So it's a extremely cheap legit way of either upgrading from an older version of Sony Vegas/Vegas Pro or Sony Movie Studio, or starting out with Vegas as your first full-fledged NLE. Vegas has a good reputation for both ease of learning and for power.

DaVinci Resolve, another NLE, is free now, but from my brief look at it, not quite as user-friendly as Vegas.

Note: you get the Vegas Pro key. You then d/l the trial version of Vegas Pro 14, which you then register using the supplied key. Also inside the install are the other items mentioned above. But without individual keys for each item you won't be able to register them. You can still use them fully-functionally for a trial period before they'll stop working. So it's up to you whether you install them in the first place or don't. If you're new to Vegas, I'd suggest installing just it first, learn it, and only then, when you're confident with it, install the extras to see if you like them.

I'm not interested in the other Magix stuff in the bundle. (If you're not aware of it, Sony sold the Vegas & Movie Studio line of products to Magix.)

This bundle offer ends in 7 days time:

Thanks for that. I mainly use SilkyPix Developer Studio Pro v6, but sometimes use RT when one of its extra features is needed.

I know you can fiddle with separate RGB Tone Curves in RT, but I think SP gets even more selective with its Fine Colour Controller.. Here is the description:

The fine color controller divides colors into 8 hues and provides a function for adjusting colors in each of the hues.

The color circle hue display shown on the control is arranged so that white is in center of the chroma chart, with color positions starting at the 3:00 position on a clock and going clockwise in the following order:

Rose red
Purple
Ultra marine blue
Turquoise
Blue-green

Yellow-green
Golden yellow

Color placement is arranged on this color circle such that the further from the center of the color circle, the higher the chroma, and they are placed at average color intervals as much as possible to meet human perception

I find the FCC useful for improving blue skies and the sickly yellow-green tint you get on grass on a soccer field when the sun is above and in front of the camera, but out of the frame. In the later case, I can separately fix both the skin colouration of the shadowed faces of players, as well as making the grass colour look more normal. And its controls seems easy to relate to.

Here are the controls:



To use, you move the mouse over a spot in the image that's the colour you want to adjust. This shows an open white ring on the diagram, indicating the current hue, so you can select the appropriate wedge. You adjust using the mouse or the sliders.
  • Dragging radially changes the Saturation. (The black dot is the default "+/-0" position for all controls in this wedge.)

  • Dragging tangentially changes the Hue.

  • Dragging at an angle changes both Saturation & Hue.

  • Moving the Lightness slider is indicated on the diagram by a change in the size of the white dot.


In this example I've made changes in both the Blue-Green and Green wedges. The changes on the image occur immediately so visual feedback is good.

One thing I like about the SP interface: the presets (you can add extra), in most sections of the program, will alter the image in real-time i.e. as your mouse selector bar moves down the drop-down list of presets. This is handy when choosing colour or contrast presets or the starting point for WB adjustment (although you can click on a grey object too).

I'm interested in what users can do in RT with this image of a kookaburra out of my back door. I didn't like the background and surroundings much, so I've close-cropped it to just show the head. This is a 100% crop: 1570 x 1303.



The standard processing chain:
  1. SP: raw development, cropping, rotation, tilt and lens distortion, Lat. CA, Contrast, Rendered Brightness aka "Exposure", Global Contrasl, Black Point, Gamma, WB, Colour tweaking, Highlight Recovery, Dodging. If further processing in PSP is required, exported as a 16-bit TIFF with no sharpening applied.

  2. PSP X7: FocusMagic (blind deconvolution OOF/Motion Blur fixing), used with Topaz Labs Remask 5 (masking plugin), if the correction is only to part of the image, or if different radii are needed for different OOF adjustments for objects on different focal planes in the image, Local Tone Mapping, Topaz Labs Detail 3 (multi-frequency sharpening), Clarify (sometimes), Resize (usually a max. of 1500 W & 1000H depending on AR), Unsharp (mild, final sharpening after resizing).


Here is a comparison of the the embedded JPEG in the DNG file on the LHS, and my production on the RHS:



While my version has some noise (ISO800), it's fine-grained and non-objectionable.

Here's the original DNG (K-3, DA* 60-250/F4, 250mm FL, 1/200s, f/6.3, ISO800), if you want to try it in RT. If you do, please post a 100% crop and the RT settings you used.

I'm not sure how to ensure the correct profile collection is being used for auto-matching. For example, how do I ensure 2018-04-03 Non-Pixel Shift is being used when I'm browsing in a directory of images? If I open one image in a directory, and then load a specific profile, will this then be used by default, if I open a 2nd image in this session? What about between sessions? Can RT be set up to remember the last selected profile collection, for auto-matching other folders yet to be loaded?
