I have a multi layered TIFF image which I’d like to flatten to reduce file size. Some layers have reduced opacity whicle others use color blend rather than normal. When I flatten the image, it changes quite noticeably. Merge down, either of all layers or one by one has the same effect. Saving as a JPEG likewise. Is there some way to avoid this? I’ve also tried the old trick of creating a new layer and then using alt+cntl+shift+e but that doesn’t paste into the new layer as it used to do. I’m using CS3. Help please

Zoom to 100 percent. If the discrepancy goes away, then what you are seeing is caused inaccuracies in PhotoShop’s preview for certain layer blending modes.

Photoshop saves time by applying the blending mode to the scaled version of each layer, instead of doing the blend first, then scaling. This causes differences when the result of the blend mode depends on fine detail.

go into the effects palette, the top one is BLENDING OPTIONS and tick the check box that says "blend effects as a group"

if that doesn’t work
select all >>copy merged>file new> and "save as"

Mike is right; at 100% it’s fine.

Kabuki’s method works well, so I’ll ise that in future

Many thanks to you both. This has been bothering me for some time
