Re: create a 'glare' effect over the brightest 1% of pixels
Here I have to use HDRI, so I use IM 7 which includes it. You could do it all in IM 7 or with a build of IM 6 with HDRI. The step does a convolution of the star pattern above with the tmp1 top 1% bright image in the Fourier domain. A limitation of ImageMagick here is that both images must be padded...

create a 'glare' effect over the brightest 1% of pixels
Hello! New to imagemagick so please forgive me if this is a very basic question. I'm hoping to create a glare effect over the brightest pixels in a photo, as in the photo below. I could see two potential ways of doing it: creating a threshold mask and using morphology to make a diamond/plus shape &a...
