Poser - OFFICIAL F.A.Q (Last Updated: 2024 Nov 15 9:11 am)
Funnily enough, I was thinking about this just today! I haven't tried the idea yet, but my thought was: What would happen if you saved both a sketch render and a normal render, then used the sketch render as an alpha-channel for a mask in a painting app, then applied effects to the normal render..? I dunno yet - but you are welcome to the idea.. In this case, taking the normal image and de-saturating the couours, then applying a mask and using the sketch version in the alpha channel and playing with contrast/brightness/tone etc. might be worth an experiment? Just a thought, Cheers, Diolma
( Sorry for the lare answer, but for various reasons I forgot I posted this message ) I'll try that idea of yours and post the result, but that'll take a while: I'm kind of new with photoshop ( all the advanced functions are still a mistery to me ) and I've got to study for my last examination ( economics and I hate it ) When you talk about alpha channels, is that the same as layers? Peevee
LOL! "Alpha-channel" is a sort of "hidden" channel, used in masks and such like. It is a grey-scale image, and acts as a filter, controlling how much of an effect is applied, according to the lightness/darkness of the alpha. (It depends on your app as to whether white or black is max, but once you figure that out the rest is easy. To figure it out, create a mask, fill the alpha-channel with a grey-scale gradient, apply a strong effect and see what the effect is, where it affects most and least.) "Saturation" refers to how close to the primary colours a specific colour is. Fully saturated colours use almost pure primary colours; de-satuartion means moving the colours towards the grey-scale; fully de-saturated colours ARE grey-scale. Hope that helps - and good luck with your exam:-)) BTW - that is just my imperfect, layman's understanding of the subjects; I suspect that there's loads of people here who can give you better, more definitive answers; also, I think there's a 2D forum here at 'rosity - asking there would certainly elicit some answers...:-)) Cheers, Diolma
