The Adobe photoshop CS3(adobe camera RAW 4.2 plugin ) conversion from RAW file to BMP file create a less saturate and dull image. May I know why this is happening?

I've tried converting the jpg to bmp and it has the same problem.

Vs. 1 or Vs. 5 bitmap?
Vs. 1 does not support icc profiles or Exif. If your image is in any space other than sRGB before the conversion to .bmp, it will have the same image data but the color space data will be gone and unless your "...assume" instruction in the Color Management dialog happens to be the same as the original space, PSCS3 will not know how to display it.

Are you using a 24 bit bitmap? I didn't know anyone still used bmp images. Why do you need to?

Yes I'm using 24bit bitmap. I use it to discard exif info.

How about just using "save for web", or use a piece of software like EXIFer (free) to remove the exif from your JPG?

Was this ever resolved? I am creating a new image for Windows wallpaper, and of course Windows converts the JPEG that I create into a BMP to display it on the screen. I saved the image out of PS CS4 as a JPEG (which looks great) and selected it as the wallpaper, and it is clear that after Windows converts it to BMP the color space is wrong. The colors are dull with nearly no reds in the mix.

The same thing happens when I save directly to a BMP from witihin PS. The file looks unchanged in PS, but when I open it in Windows Picture Viewer, the image looks like the dull wallpaper.

I have made sure that sRGB is the color space. Clearly I have changed something in the settings, as I have created many wallpaper files in the past and have not had any problems with the resulting file.

Any suggestions are welcome. Thanks.

OK. Fixed. The image was in ProPhoto RGB in Lightroom, and the color settings in PS wereset to preserve the embedded profile, so it was not being converted to sRGB.
