K 5-II and Silkypix - About color

I don't know exactly what you mean by "optimize colour" ? But when I send a jpeg to my printing company it is in sRGB colour space and I do not expect, nor will they do, any "colour optimization". The whole point of a professional printing company is that they will not try to "enhance " anything. That is your job before you send them the file.

Otherwise who knows what you are going to get back.

Have you tried resampling an image to 15748 x 11811 resolution ? Look at in 100% view. A print that big will be viewed from further away than say a 24"*16" print, so it is not expected to have the same appearance close up.

I am sure it did. I took additionally my M 50mm 1.4 and M 20mm 4.0. I used a yellow filter (b+w film). Luckily i used the 20mm last as i had a problem to deal with when I was finished. On the 20mm lens I use a generic wide angle hood which requires a 58/49 step ring which I screwed into the front thread of the filter. Disassembly time and the step ring has fixed itself firmly to the filter thread. No amount of fiddling and swearing would part them. If this had happened when I started i would have not been able to use the filter on the 150 and be able to pull the built in hood out. Or use the filter on the 50mm and use its own hood for that.

I am sure she enjoyed it as much as i did. It really makes you stop and think about what you are doing regarding framing and exposure, and that is no bad thing at all.

As an example here is an image of my dog Rio. One has been converted with settings of Strong contrast; Memory colour 2; and a saturation boost from 1.00 to 1.22. It has had sharpening applied using USM. The other is a default setting with no adjustments and no USM. maybe the bold colour is not to everyones taste but you will get what I mean.

Hi

I will attempt to answer. First I use Silkypix DS Pro7 and have used the product for many years , it is a great raw converter.

1. You are shooting raw files .PEF. Raw files contain the most detail, but MUST be processed to bring out the best in them. A raw file processed without any adjustments will give you a dull lifeless image.
2. Which adjustments to make:

White Balance. I find the camera usually makes the correct choice on auto, but for consistency over a number of shots use one of the presets in Silkypix. The most accurate way to select WB is to shoot a grey card in the scene. Tip... set the white balance first for the first picture, then use Cntrl-C/contrl-V to copy and paste that setting to the other pictures.
Exposure Bias: Set it to compensate for under/over exposure of the scene.
Contrast: I have mine set to Strong Contrast as default. I like punchier contrast generally
Colour: I have mine set to DNG Memory color 1 as I like strong bold colours
Sharpening /noise reduction. Leave those on default for the moment.

You can save your settings above as a Parameter so that they will always apply when you open a raw file in Silkypix. You can adjust any settings further if you wish. i suggest you have a good look at each of the above settings and the sub-controls that appear beneath when selected. For example clicking on the Contrast allows you to select 8 presets from low to high, but also reveals the sub controls for Contrast slider/Contrast Centre/Gamma and Black level. Use the information Icon to open the manual for these settings (it will open at the right page) to understand more.

There are numerous other tools which are useful. The HDR one especially you should look at. Also the Lens Aberration controller will correct vignetting (shading) and lens distortion.

Once you have your pictures looking how you want it and cropped you need to convert it to usually a .jpg file. Set the size you want in pixels then select the Unsharp Mask tab......

UNSHARP MASK or USM is a technique that goes back to film days to sharpen an image. Your file will have had default input sharpening applied already (see comment above), but USM is ouput-sharpening and will depend on a number of factors to get the best result. Have a look here for a good explantion of USM Tutorials – Sharpness and here Sharpening Using an Unsharp Mask View your image at 100% view to ensure you are not adding halos or other artefacts. As a rule on My K1 I use Amount 25-65 / Radius 0.6 / Threshold 1. and this can also be saved as a preset to speed up your workflow. If you are going to be printing your image i suggest doubling the settings 50-130/1.2/2. The larger the print the more USM you should use.

Once you have got a feel for the different setting in Silkypix learn how to use the presets and batch processing. i can generally very quickly batch process a number of general images using defaul settings with a bit of individual tweaking. Have a play and come back with any further questions.

Finally printing. You said you were not happy with the results. Printing is another field entirely. If you want accuracy in printing you need first to colour calibrate your screen using something like a Spyder or Colormunki. Second you need to to learn about colour profiles and your printer settings. It is a daunting task which is why i don't print myself but use a commercial company.

Good luck

Just to answer this point directly. If you are going to use raw (PEF or DNG) you must process the picture. Try this as a test. Set your camera to RAW + JPEG. Open the raw file in Silkypix with all the settings at default and next to it open the JPEG in any photo viewer. You should see a marked difference between the two. This is because your camera has "processed" that raw file to create the JPEG. If you want your raw image to look as good you need to also "process" it. You may even end up saying "to hell with this the camera JPEG is good enough for me" !!

I think he means saving the "Digital preview" that one gets as an alernative to "optical preview" using the DOF preview button.

Never use digital preview, so cant help.

I do understand what you are saying here, but as a user of both these lenses I can assure anyone considering a purchase that the 24-70 and 15-30 are very much "real" lenses. :)

That means using the "sensor clean" menu of the camera to lift the mirror out of the way so your blower can get access to the AF module. This also means the sensor is exposed so don't prod it with the blower head. Keep the camera mount pointing down at all times.

ps....don't sneeze

K3ll EV Use

Think you are mis-reading it.

EC in TAv mode will compensate by increasing/decreasing the ISO by the amount of EC you have dialed in.

There are two situations where the EC compensation will fail:

1. if you dial + compensation which would take the ISO above the limit you have set for Auto ISO. Solution is to remove or raise the limit on Auto ISO.

2. when you dial in - compensation and this would take the ISO below the minimum (100).

You have written EV. Are you actually meanung EC (exposure compensation) ? Or something else ?

EXIF is stripped on these images.

If the AF540 is firing a pre-flash but not main flash make sure it is not set to Wireless "Controller" mode. The flash on off button should be firmly in the on position, not at the halfway Wireless position. What does the panel say the mode is ?

i don't know if your Sigma is compatible with the K1. it is quite an old model so possibly not. If it should be compatible and is also not working then perhaps the fault lies with the K1 hotshoe/electronics.

Can you find another Pentax flash to test on your K1
