K100D RAW Files and Photoshop

Hi,

I'm using Photoshop Elements 4 and Photoshop CS2 and as much I can see, they don't support RAW files from K100D.

Any suggestion about this?

Regards,

Zé

Convert them to DNG in Pentax Photobrowser and then open then in Photoshop if you wish, but I think browser does a great job converting.

You'll have to wait until Adobe releases a plug-in that supports the new PEF format.

And another solution:

change in RAW file K100D into *ist DS and all software which supports DS will support K100D

Sorry to ask but how does one change the K100D to *ist DS in the RAW files. Call me crazy, I dont know if this makes sense, but converting from PEF to DNG using the Pentax software, ruins my images (I lost a lot of colour information, colour detail tends to all blur).

I had the same issue converting to DNG. Quality suffered, and colors were out of whack. Until Adobe releases an update, I'm converting PEF to TIFF and doing all my PP work in CS2.

Open K100D PEF file file in any hex editor and change "K100D " to "*ist DS". Save PEF file. Now all software will open it as PEF file made with *ist DS. However this method suck if they changed colour mapping in K100D.

As far as I know, Adobe DNG converter use lossless compression for proprietary camera format RAW data and saves all camera maker data into DNG file. Therefore you either use outdated DNG converter or your software isn't able do decode DNG files correctly or you just imagine those differencies.

Have you tried to make blind tests? Convert some PEFs to TIFFs and then the same PEFs to DNGs and to TIFFs, ask someone to rename files so that you wouldn't have a clue whwhat was origin of TIFF file and then try to tell with accuracy significantly larger than 50% which TIFF was made directly from PEF and which TIFF had intermediate DNG file

Hi,

Had the same problem recently with istDL2 and a new plugin was the only good way in the end.

The short cuts and file changes were not a good result.

Adobe is usualy not far off with a new plugin and you will find full instructions on where to put it on the Adobe web site, follow the link below.

If at first you don't succeed don't try sky diving.

I should also have mentioned you will be looking for "Camera Raw 3.* Update" file it will most likely be a "3.5" version.

Good luck.

Once it is possible to open both PEFs and DNGs into Photoshop or some other photo-editor with layers, it doesn't need a visual examination.

The test I use is to make both versions layers in the same Photoshop image, then use "difference" blending mode on the top layer. Using "info" and "Trim" does the rest. Here is some stuff about testing whether DNG is doing anything bad:

I have just done this test with a K100D PEF that has been hacked to look like a DS PEF. The PEF-route and the DNG-route give pixel-identical results, at least in 8-bit mode which is a good enough test.

Good morning guys,

If there should in theory be no difference between converting to DNG (using the Pentax software) and then to JPG (with ACR) compared to converting straight from PEF to JPG (using Pentax Laboratory) I need some help.

I have posted two images on Picasa (it is the only image site I have access to). If you look at the purple flower in the first one there is no detail in the petals, all the colour has blurred together. I have done nothing but convert one image to another, no touch ups as far as I know.

Can anyone thing of what I am doing wrong? I would really appreciate some help. If you want I can see if I can upload the PEF file somewhere too.

Thanks alot
