Title: Grayscale Changing in Photoshop 7
Post by: NHawk on July 16, 2010, 07:08:25 AM

This is an interesting problem I've never seen before.

If I open gndtype.bmp in Photoshop 7, all seems OK until I start using the eyedropper to check color. Grayscale 170 varies from 168 to 171 and none of the other colors match what they should be. Needless to say, if I save the bmp like this it totally messes up the terrain ground types.

Anyone else seeing this?

BTW... I'm running Windows 7 - 64-bit Ultimate.

That's been a common problem with GIMP as long as I've been using it, so makes me wonder if someone is lifting code, but on which team hehe. ;)

Really, is this new to PS?

I really don't recall it ever happening before.

I wouldn't be worried about it, except I was trying to set the terrain types more precisely and boy did that color shift mess up a terrain. Had odd combinations and some totally unrecognizable terrain types pop up.

I may pop Photoshop and the TE on an older XP system to see if it happens there too.

When I'm working on th grndtype bit map, in Photoshop, I make all my changes, then
I change the file type to greyscale and then change it again to indexed.

I'm using CS3. Never did like gimp.
Any way that will fix you index number changing issues.

LOL, no need to bother changing to grayscale.

It seems leaving it as indexed through the whole process solves the problem.

Thanks!

I was going to say, if you work with it as an index file, it will not shift around on you.

I'll be trying this with GIMP too. Sounds like a good tip.

Thanks fellas.

I'm sorry I should have mentioned why I  do that. I usually convert the image to an RGB image because I'll be working with layers.
Then I do those conversions.
