I am using a levels adjustment layer. The image is from a scan of one of my drawings that I am preparing for prints so this editing is critical. The values need to be spot-on and I have adjusted the levels to what I think is the best settings but when I go to flatten the image the overall tone becomes slightly brighter. I have tried merge down, flatten image and flatten visible with the same results. Why, when I am using an adjustment layer, would the image get brighter when I flatten it? This apperently happened on my last image and I didn't notice, until we had to deal with the tone during the printing. What can I do so this doesn't happen other then applying the levels setting directly to my image? Thanks in advance.

I just discovered that it has nothing to do with the adjustment layer but to levels itself. When I apply level to just the image and adjust my settings so they look right and then hit Ok the image brightens slightly. I am adjusting the black point and this small increase in brightness is not acceptable. Maybe I need to over compnsate in levels but that is not a desirable solution. Any idea why this is happening?

| When you go into the layers dialog box is that levels layer in the normal mode? Opacity 100%? |

Yes and yes. I actually just figured this out but I am glad I asked because what I discovered is pretty interesting. I knew that the on-screen zoom magnification was relevant in relation to the appearence of graininess or smoothness in your image (this is why you should view sharpening results at 100% magnification) but I didn't know it could have to do with the overall values too. I was making my levels adjustments at 25% and less magnification so I could view the whole image at once. When I finally zoomed to 100% on a particular area and then merged or applied the levels settings the values remained constant. I was making my ultimate decision based on a printed proof anyway so regardless of what effects I see on screen I am assured that my settings are correct. This effect is likely more pronounced because my image is a drawing which was drum scanned so every singe pencil mark is accurately represented. In other words it is not at all continuous toned. Lesson learned: Even when making tonal corrections be sure to also view the image at 100% magnification.
