Used this generated image
>>7150890, edited out watermark & saved as PNG, then re-uploaded it and ran it through the filter recursively. Original:
>>7150891I've been pushing the colors & saturation & etc. around a fair bit to see what effect; so far it's been fairly minimal. The grayscale version of this one was less satisfying because, while mostly the same, it lacked the intense red in the flash at the gun muzzle that kind of made the focus of this interesting.
Also, according to IrfanView, the images generated are saved as 75% compression jpeg. As previously, this one is in PNG because that's how I saved it after editing out the watermark.
The other filters for this one just didn't look interesting enough (to me) to save them. Anyone interested, you have the original to play with.
