Flatten layers without losing effect

Hi,

     I'd like to know weather there is a solution to save a PSD document with some layers under another file type (such as .JPEG) without losing effect when layers are flattened ? Each time I want to flatten some layers with different blending modes, I get a very different effect that is unwanted. Thank you in advance for your precious help !   

Best regards

    Hi

    Flattening does not normally make a drastic change provided you are viewing before and after at 100% zoom. Other zoom levels are blended using previews and you may well see a change.

    If you are seeing this before and after at 100%, post your layers panel (or better an example file, and we may be able to help you better

    What I do when this happens is to add a Copy merged layer to the top of the stack. 

    Select the top most layer (it must be be turned on) and Shift Cltr Alt E — Shift Cmd Opt E

    It will then flatten without any change in appearance.

    Chris Cox did once explain why and how this could happen, but I am buggered if I can remember, and my lazy method works so that's what I do.

    The preview Photoshop creates can use downsampled cache-imagery to increase speed (unless a certain Preferences setting is set).

    So the effect of the Layers, BlendModes etc. may not calculated at the full image resolution but downsampled stand-ins, which can for example result in grey pixels being adjusted when actually there are only black and white pixels which would not be affected.

    I had a discussion with Noel Carboni a few months ago where he explained exactly that. It does beg the question as to whether such preview blending is needed with modern graphics cards and high speed processors.

    I assume you do not view the image at View > 100% when flattening.

    Thank you so much for your answer. For the moment, I don't know if it solves my problem but I suppose it does. Thank you all of you anyway.
