ACD JPEG display problems

351 views6 repliesLast post: 8/31/2004
For some time now I have felt that ACDSee was displaying my B&W JPEG images a bit 'gray'.
I finally did some testing tonight and discovered, to my shock, that a JPEG B&W image saved in grayscale format, and a copy saved in RGB format will display differently in ACDSee. The highlights 'gray' ever so slightly in the grayscale format JPEG. The RGB version is true to the original.

Interestingly, if TIFF format is used, the images are identical and correct with the PS original.

Anyone else noticed this?

Yes. When I want a black and white pic I just slide the saturation bars all the way down and leave it rgb.

I never bothered to check, but does compression level make a difference?

Don't know, but Grey scale doesn't work for me when doing a black and white pic to put in an ad. Perhaps there is a correct way to do it, but like I said, what works for me is just sliding the saturation bars all the way down. Right or wrong, it looks better than grayscale when it's printed in a magazine. gray scale just looks flat.

B&W rendition, this being a little aside from original subject, but may be useful to some :

Add a channel mixer layer, tick "monochrome", set R to 24, G to 68, B to 8. Tis is is the method that yields best rendition, to my knowledge.
