this question is targeted at people who understand something about fourier transform and the image pyramid.
Is there some plugin for photoshop that allows me to edit only a particular frequency band of a layer?
for example, sometimes you have an image that looks quite alright in the details but you have some low-frequency gradient going over the whole image that you'd like to get rid of.
it'd be great to decouple low and high frequencies of the image, edit only the low frequencies and then recomposite them again.
hope you know what I mean and maybe you know a way to do this?
thanks!
