jeff_collins Posted June 16, 2005 Share Posted June 16, 2005 I shot over 200 B&W images (RAW format) yesterday using my Canon20D and then downloaded the images without any difficulty. But as I was looking at the thumbnails in Photoshop CS, I watched each and every image turn from B&W into a color image. Is Photoshop CS supposed to do this? It seems a bit silly to use the B&W settings in the camera if Photoshop is simply going to add color on its own. I know I can desaturate the images but it was my intent not to have to do this. Anyone experience this? Thanks. Jeff Collins Link to comment Share on other sites More sharing options...
denisgermain Posted June 16, 2005 Share Posted June 16, 2005 rule #1 - never use those special effect things in the camera... B&W images cannot be turned back into a real color image... they can be colorized at best..... Link to comment Share on other sites More sharing options...
bobatkins Posted June 16, 2005 Share Posted June 16, 2005 I don't think 20D saves images as B&W in RAW. RAW is RAW. It's unprocessed output from the sensor with color in intensity info. All the B&W setting probably does is insert something in the file header that tells the Canon software what parameters to use to convert to B&W. CS probably doesn't understand that header info. Can't for the life of me see why anyone would shoot in B&W anyway. If you want all the shots done with the same conversion parameters, just batch process them. The 20D always shoots in color. B&W is just a software based conversion. If you want B&W images saved by the 20D, you can probably do that if you select to save the files as JPEGs.

glen peterson Posted June 16, 2005 Share Posted June 16, 2005 Try using canon's EVU, or DPP software to convert your raw files. It should work better. Link to comment Share on other sites More sharing options...
awindsor Posted June 16, 2005 Share Posted June 16, 2005 I don't have CS or CS2 but I believe the problem is that Adobe Camera Raw does not recognize the B&W mode of the camera. (The RAW image is not processed but the fact that you chose B&W mode and any filters is recorded in the proprietary part of the EXIF). If you use the Canon software then it will recognize the B&W mode and know if you shot it with a special filter. I always apply such things afterwards but sometimes it is useful to be able to see a B&W image on the LCD to judge tonality. Thus the B&W mode is not entirely useless.
