Yea I still have the psd. The background is currently black but I want to change it to white, which is why I want to remove the flare. I just can't figure out how to remove it. I was thinking about using the patch tool but I'm not sure if that would work.
Is it all pixels, or do you have things in layers? I think that was the basis of Frank's question. If, for example, you have the lens flare in a layer, mixed with those below with e.g., Screen blending, then you'd just be able to shut off that layer by clicking the eyeball icon (making the layer invisible).
If you rasterized everything and rendered the lens flare in pixels, well, then you probably need to re-render the text in the portions of the image where the effect.
There is no magic "remove flare from pixels" tool.
