Photo Laboratoy problems

With my new k100d I made a few test pictures in RAW ( .pef) and tried to use Photo Laboratoy (v 3.10) to convert them to JPEG. The preview and the JPEG both produced totally crippled pictures. In the preview the almost every pixel has a red value of 11. Photo browser shows the correct image. I use these programs on a win-XP laptop.

Any ideas?

Looks like something is seriously wrong. JPEGS from the camera are OK ? Tried another converter, e.g. adobe lightroom (to be downloaded freely) ?

I do believe Lightroom does not understand K10D .PEF files.

If you do want to try another converter I would suggest you get the Bibble beta which is a free trial and definitely does process K10D .PEF files.

It could mean the white balance needs to be corrected.
Click on the White Balance from the View menu.

You can manually correct it with gray point setting (if you have gray in your picture)or use the override presets (daylight, shade, cloudy, tungsten....). I hope this helps.

I'm still not real good at curves but I have figured out most of the Laboratory. The great thing about RAW is you can keep redoing it without ever changing your original.

If it looks OK in browser then it should look OK in the Lab preview as well.

I would try uninstalling and reinstalling them both and if that fails, download them from the website.

Just check that none of the tick boxes are checked in LAB when you initially open it and that you have ALL windows open.

Ok, I lied. There is text.

Judging a photographer on the basis of equipment is like speculating one's physique from a gym pass.

Old eyes - small font on site - visually ambiguous numbers by Pentax = OOPS

Sounds like there may be a wrong setting in Photo Laboratory. You might check the Tools:Options menu, General and Advanced tabs. One possibility is that "initialize parameters ..." is set to NO and you're retaining some weird adjustments. I'd use the RESET button to make sure all of the settings are "normal" and see what effect that has.

Is Photo Browser set to Simple Display or Auto RAW Display? Simple display uses the JPG info embedded in the PEF file, so it should be a little different (though normally lower quality) than the preview shown by Photo Laboratory. If you are using Auto RAW Display in Browser, the prewiews from Browser and the initial preview in Photo Laboratory should be essentially the same..

Thanks for all the advise, the explanation is a little different. The ill performing RAW files were all saved by Pentax remote assistant. It appeared that all raw files on my sd card are OK. So it appears that remote assistat, when controling a K100d that is set on JPEG, saves the files in a different format which is not correctly read by Photo-lab.

The solution is simple, select the raw format on the K100d before using remote assistant...
