It's the internet's biggest failing... actually, a problem with all electronic communications - text messages, e-mails, social media, forum discussions... If we were all sat in a pub with a beer, talking things over, our disagreements would be enjoyable banter 99% of the time. But when you can't see someone's face, can't hear the tone of their voice, it's so difficult to judge each party's intentions. I think we all mean well, (almost) all of the time :o :lol:

Can you update just the camera profiles in LR?
Posted By stevebrot

You can still update to LR 6.x (perpetual) and you will require at least that major version in order to have full Adobe Standard and K-1ii Camera ("bright", "landscape", "natural", etc.) support for both PEF and DNG. If shooting with DNG only, LR 5.7 will support your camera's files, but with the embedded profile only. The catch is that even the most recent update for LR 6 lacks the camera profile files for the K-1ii. Getting them is not hard, but actually using them requires jumping through a few hoops.

First of all, one should be clear on what the camera profile (.dcp) files do and what they don't do. In short, they contain instructions for the RAW processor on how to best massage the capture data for a good initial rendering (e.g. "Adobe Standard" or "embedded") or to render with an intended special effect (e.g. "Vivid", "Sepia", and such). The are also specific to DNG unless the camera has native support for the Lightroom or ACR version being used. It is also possible to create special custom profiles for specific lighting or subjects. Camera profiles do NOT provide support for camera features such as pixel shift or HDR. They are also NOT the same as Lightroom presets; the profiles are applied as part of much lower levels of processing and leave the sliders in their default positions. They are also not the same as icc color profiles, though there are some similarities.

So, where are these profile files? For most Lightroom installations they will be found at:

HTML Code:

-- LR installation directory


-- Resources


-- CameraProfiles


-- Adobe Standard


-- Camera

Conspicuously absent will be files for your K-1ii. Without them, LR will not be able to process PEF at all and will default to the embedded profile found within the DNG file. There is nothing wrong with the embedded profile except that its look will be somewhat different than that of "Adobe Standard" or whatever profile you might want to use instead. While even the most recent versions of LR 6 lack the .dcp files for the K-1ii, it is still possible to get profile files for it and for all other cameras supported in the most recent versions of ACR (Adobe Camera Raw) through the Adobe DNG Converter tool. While the primary purpose of the DNG Converter is to create DNG from proprietary RAW and various image files, it also comes bundled with a full collection of camera profiles current to the date of the converter version. In other words, the current version of the DNG Converter copies the profile files for the K-1ii to the computer hard drive as part of the install procedure from which they may be copied for other purposes.

The DNG Converter tool may be downloaded from:
Adobe Digital Negative Converter
Follow the instructions for installation and continue as directed below.

Happily, one does not need to convert any files to make use of the bundled .dcp profile files. Instead, one merely needs to find them and copy them to the directories used by Lightroom for the user's custom profile files. For Windows the bundled profile files will be found someplace similar to this:



Note that the "ProgramData" directory may be a hidden system directory, but exists none-the-less. If unable to find the profile file directory, do a file search for *.dcp (all files with the .dcp extension).

When the profiles are found for the K-1ii, copy them to the user's custom profile directory. For Windows, the user's custom profile directory might be something like this:



I know this is a little complex, but may be worth the effort. At one time, there were detailed instructions from Adobe, but those seem to have evaporated. :(

Aperture on life support, what should I choose?
Posted By MJSfoto1956

I'm not a good one to ask. I'm currently devoted to DxO Optics Pro as the first step of my workflow. That being said, there is much complaining online about AP's RAW converter -- I think the reason is pretty obvious: Adobe does much more than just "convert" a RAW file -- they build in a "look" which is frankly an Adobe look (which is analogous to the Kodak film look vs Fuji film look argument back in the day). I don't think AP should attempt to duplicate Adobe's look but rather just provide built in tools to allow the editor to choose which to "improve" the conversion -- which is precisely what they have done. An expert will have no problem using AP as their RAW converter as long as said expert isn't expecting a push-button approach to RAW conversion. I learned the hard way with DxO. At first I couldn't understand how my RAW conversions were worse than Adobe's. After I got over needing to have a push-button solution I learned how the tool really works and today I get consistently superb results. Ideally there would be a smooth/seemless integration between DxO and Affinity, but I'm not counting on it. Instead I'm happy using DxO to get my images 80% there and Affinity to fill in the remaining 20%.


P.S. one unusual feature of AP I discovered by accident: I always save all my images on a networked SAN. And saving a big file can be slow. With PS each time I save a large file can take a good long while. However with AP only the initial save takes any noticeable time. Subsequent incremental saves are generally instantaneous as only the deltas are saved. This feature alone has sold my on Affinity's approach, which in my experience is unique.

I created camera color profiles with an X-Rite ColorChecker for all Pentax cameras I own(ed) and am happy to share them with you :cool:
There are profiles for the K-5, K-5 II and K-3. They come in two varieties:
  • created with the standard X-Rite software that comes with the Colorchecker (marked "X-Rite")

  • created with DCamProf, a free new camera profiling software developed by Anders Torger

You can find more information about DCamProf here: DCamProf. It's command-line only and not easy for beginners, but IMO the results are fantastic.
The killer feature of DCamProf is the so-called "neutral tone reproduction operator" it uses for the embedded tone curve: More Info

I just added f-numbers, so you can see yourself. I shot the GR with slightly lower values, and they seem to improve slightly. So maybe I didn't quite capture the GR's potential. However, as you can see in the last GR picture, even though the starbursts are quite ok, they are nowhere near as great-looking as the DA15's.

These two pictures are under very similar conditions and same f-stop:

Yeah but so what? 16MP APSC is already 36MP on FF. You know it works then. For 24MP APSC, you can just look at the crops available on the net, look at the photos, ask the one that now have a K3. If you need to try to know then try. If you think you need to try but doesn't try and then raise concerns, there a bit of inconsistency in your argumentation to me.

The shutter speed is a false argument. You should have the shutter speed that match the intended framing. If you hope for a 300mm shoot using a 300mm lense on APSC you need a 1/500 or faster without shake reduction. That you get your 300mm framing from a 300mm lense, or from a shorter focal length like a 135mm or 200mm, the speed should be at least 1/500. Shake reduction can drastically reduce it as can a tripod/monopod. But from a practical point of view it doesn't change anything to use a shorter focal length and crop or use the proper focal length and not crop for the shutter speed.

Here just as one example a DA50-135, a 80mm shoot and a 100% crop of K3. The reframing is equivalent to 400mm, so 5 time the focal length:

It was 1/250s at f/5.6, for a 400mm on APSC, this mean the speed should have been 1/600s. You see that SR indeed really works.

IMGP2661 by Nicolas Bousquet, on Flickr

Most primes and most quality zoom would do it without issue in the f/4-f/8 range.

Anyway I think the discussion is not for your or my lenses. We speak of a 5MP being enough or not and why Canon now has decided to offer a 50MP FF (and 24MP APSC). Our lenses would not be ideal for such body anyway.

This would not prevent for one to buy it, use some Canon primes on it and benefit of the resolution it provide.

Lens correction for manual focus lenses?
Posted By stevebrot
Replies: 26
Views: 2,020
OK...I just reread your comment carefully and think I found the disconnect.
  • PDAF Focus confirm uses exactly the same mechanism as the PDAF auto focus

  • The system attains focus by detection, not by prediction. That being said, the point of detection for PDAF may not correspond to the true focus point due to the optical characteristics of the lens (flat, indistinct, or asymmetrical phase peak).

  • My understanding is that AF adjustment is a simple bias onto the system (shifts the detector off-set*) from the factory setting. Physical sensor position is not altered.

One last thing...AF adjustment applies to PDAF only. CDAF and focus peaking in live view are not adjustable.


* I have no information as to the exact process mechanism, but I have a few ideas.

I was wondering when someone would say this. If the brand of gear is a serious problem, then you just switch. It shouldn't be a big deal. But this whole thing seems kinda "iffy" to me. 99% of the public doesn't know a fraction about cameras that most folks on this board know, so I'm finding it hard to believe that couples would have such strict standards. If it were me, for the time being, I think that how I answered questions about my gear would depend upon what was asked. If someone asked, "What brand of camera do you use?"...then I would tell them I use a Pentax. However, if they asked, "What kind of camera do you use?"...I'd baffle 'em with BS. I'd say something like, "I'm glad you asked. We use an APS-C camera with a 16.3 megapixel CMOS sensor that has a top shutter speed of 1/8000th of a second, can shoot as fast as 7 frames per second, and is usable in dim light up to an ISO of 12,000. We shoot exclusively in RAW format, but will provide low-resolution JPEG images as your proofs." If that's not enough, you can talk about the range of your zoom, how many elements it how may groups...the number of low-dispersion elements in it...widest aperture, crop-factor, etc... Before long, they'll be saying, "Okay, okay...just shut up about it! I'm sure it's fine." :lol:

Crop Factor Thoroughly Explained
Posted By Rondec
Replies: 30

It isn't rocket science.

The APS-C center just crops the middle of the full frame sensor to produce a smaller sensor (hence the term "crop" sensor). The problem is that people have claimed that this cropping does weird things to their lenses. It makes their 55mm lens an 85mm lens (it doesn't). It makes their f2.8 lens an f4.5 lens (once again it doesn't). Crop lenses aren't necessarily much smaller than full frame lenses, particularly if the lens mount is kept the same. Most of the benefit in size with Pentax's lenses has come from them being relatively slow lenses compared to full frame options that are available.

Exposure varied between lenses
Posted By Lowell Goudge
Replies: 22

Years ago now, when exposure metering was a big topic, I ran a ton of tests, using my *istD and K10D. I have since continued on with my K7D and K5D

Exposure carries between bodies with manual lenses, and between lenses on the same body.

Even adding a teleconverter changed the exposure of my sigma 70-200/2.8

What I found is that the exposure with manual lenses is quite non linear as a function of the camera and focusing screen and the actual aperture you meter with. For A lenses, the camera is largely compensated with the aperture knowledge and very close to correct.

You should test every lens with every body, taking a series of shots using a uniform surface such as a paved road or block wall.

Even modern lenses like my Tamron 28-75/2.8 have some irregularities, it is perfect wide open and gradually exposes more and more when stopped down until it is one stop over when fully stopped down.

Shooting a series of shots to validate exposure on each lens is a worthwhile 10 minutes per lens spent to know your gear.

What My Dad's Slides Can Teach You (and Me) About Photography
Posted By yucatanPentax

I'd just like to add, perhaps as a bit of uninvited advice (sorry), don't be too quick to "trash" the "trash."

As time goes on, even those out-of-focus, too much sky, too much foreground, shots may prove to be irreplaceable treasures. You get an insight into your dad's thinking 20, 30, 40 years later. Maybe there is "too much sky" because to him at that moment, it was just so, so gorgeous. Maybe the smell of fresh-cut grass reminded him of a long distant farm life and there's too much foreground as a result. He may have made technically "lesser" photos, but that doesn't mean there's nothing of value to find, especially for loved ones.

At this point, you're lucky to have both your parents around. You may find memories and perceptions shift dramatically when they are not around to talk with, share memories with, and delve into their thoughts.

I know this is supposed to be about photo technique, but looking at anyone's decades-old photos tells a lot about the moment and the person's frame of mind. Sometimes, it's nice to think about those things in addition to technical excellence.

The train engine... I've been in that situation before. You're traveling somewhere and you want to get a photo of something, but there are all these danged people around. Maybe your dad could have gotten a better lighted shot from the other side, but also, maybe that side was crawling with throngs of people blocking any view of the engine. So he goes to the other side, as I've done too often, and got a shot of the engine. Technically, the light isn't perfect, the time of day isn't perfect, but you can see the engine.

"Perfect" shots often take a lot of time that traveling / tourist people don't often have. You have to shoot what you can, when you can. I've got a list of maybe 100 places I'd like to be at the perfect moment of sunrise or sunset (or just before or after), but I have to work and make a living too. One of these days... One of these days....

K3 doesn't report lenses in EXIF
Posted By stevebrot
Replies: 17
Views: 2,219
The lens information is there in the makernotes section of the exif, but it is stored as a numeric code that may or may not be understood and mapped to a meaningful name by your software. Here are a few bullet points:
  • If you want to confirm the code for your lens, Phil Harvey's Exiftool is free and is usually up-to-date with support for all but the most recently released cameras and lenses. Unfortunately, while powerful and comprehensive, it is a little opaque to many users who are not geeks.

  • Adobe support for Pentax cameras with newer lenses is spotty. Lightroom 5.6, for example, properly parses and stores the lens code in the catalog on import, but may not map it automatically to the appropriate lens profile nor display the lens name. Go figure. I don't know about other software vendors.

  • Only lenses that have a data pin (all K-mount AF lenses) will transmit a lens code. For others the lens is coded as "0 0" (non-conductive mount/no lens), "1 0" (conductive mount K or M series), or "2 0" (A contacts present, no data pin, A series).

  • For a full list of codes known to Exiftool (exhaustive, but not authoritative) see LINK.

More than you ever wanted to know, eh?

Trouble finding lenses

Replies: 16

I see this advice here a lot and tended to consider it sound. However, the primes I have & love their results (43 & 50) are in focal range I had the least photos taken by kit. Most were taken at 18-28 range; a range I'm not to eager now to get a prime in.

I got 50 because it was the cheapest 'good' prime. FOV was awkward and demanding, and yet, many of the 'best' photos I took this year were taken by it. Being forced into a focal length made me more aware of framing and composition, and consequently resulted in more pleasing photo. Now I'm pretty comfortable taking 50 for a stroll; I'll find a way to use it.

I got 43 because an opportunity arose I couldn't pass. I probably had no photos at all at this focal range, and yet, now it's glued to my camera.

Exploring what focal length is 'easiest' or 'natural' for you is common sense, however I suggest you don't limit yourself to your comfort zone. Sometimes being forced to work in a less used focal length might improve your skill more. So, check the marketplace for affordable 'good' glass in ballpark of what you want to shoot (wide/normal/tele) and go for it.

KS-1 vs K-3 for Street Photography
Posted By stevebrot
Replies: 35
Views: 8,174
FWIW, one of the best street photographers that I know does not rely on stealth. In fact, he often actively engages with his subjects.* I dabble in street work when feeling brave and can make these generalities:
  • Large camera = bad (intimidation factor)

  • Large lenses = bad (see above)

  • Vintage or rough-looking gear = good

  • AF is not your friend, better to shoot the hyperfocal in manual focus

  • Moderate wide-angle = good (35mm on FF or 24mm on APS-C)

  • Shoot single shot = good (machine gunning makes the subjects feel like prey)

  • Being intentional = good

  • Command of the gear = good

  • A ready and genuine smile = good. This point and the two preceding shout professionalism and respect and allows your subjects to feel flattered to be part of your photo.

  • Don't steal the shot, the subjects are not prey

  • Don't capitalize on poverty or disability. The human condition as a subject borders on the immoral.

Hmmm...not a lot about gear in that list. What is my choice? My favorite is the FED-2 rangefinder (ca 1961) with a 35mm lens attached. Second choice is my 70s vintage Ricoh XR-2s SLR mated to the FA 35/2. As noted above, the K-3 works fine except that it is a bit heavy for the task.

I have, probably, a lot more software for PP than most.
By and large I've found that, say, a given method of sharpening, contrast enhancement or whatever is not better just that it works differently for different software.

I think the the most important skill for PP is the ability to evaluate a file to see what it needs and to come up with a workflow with appropriate software for that particular file. There's no good or bad or right and wrong only optimal choices.
