for those of us working in paint shop pro, here's a screenshot of a fairly close equivalent to Ro's. you can see the workflow on the right in the layers palette. it's pretty similar. notice that i used 'soft light' for the blend mode instead of Ro's linear light, but it's close.

there is also a bit of a difference in the glossiness and highlighting. i think this may be from the differences in the high pass of the respective programs used.

you may also notice that i put a contrast/brightness adjustment layer up there just to test something, but that it's turned off in the screenshot. so, disregard that for approximating the shot.

you may also notice another layer turned off. this is just because of how i work. i made the high pass first, then duped it and turned off the original layer and then ran the gausian on the duped layer. this is the same as running both processes on one layer if that's how you prefer to work.

notice also that i put the soft light blend on the mask group as a whole and not on one of the individual layers within the group.

very nice, Ro.

i'm just curious how you would figure out what settings to use on different dpi images.

example, that workedfine on an image that was 72dpi...but I couldn't figureout how to set it for a high or med rez image like 300dpi or 150dpi etc.
i havent tried this yet, but theoretically all you'd have to do is change the radii used in the processes depending on the dpi and image size. remember, a radius is half the diameter of a given something. so, figure the dimensions of whatever it is you're working with...get it's diameter and halve it for the necessary radius setting. ....theoretically

Exclamation Radius

Having a little trouble figuring out the settings for much larger images...

Just curious how everyone else would figure out how to setup their settings.

Ex. If the image was 10 x 12" @72dpi and the settings were as: HP:10 GB:3.3

How would figure out how to apply that same setting (effect) to an image that was:

30 x 36" @ 300dpi?

Woah there folks! Those radii aren't set in stone, they're just what worked here. It's going to depend on the image - each one is a little different.

Basically you try to find a point (radius setting) that divides the pores from the grunge, and another point that divides the grunge from the facial features.

In general, yes, a bigger image is going to need a higher radius.

I'm going to write the tutorial tomorrow (got a couple of beers in my head now ) but basically I do this:
- Run a high-pass and look for the point that the grunge doesn't appear any more but the pores are still intact: remember this number (~3px) and cancel the filter.
- Run a Gaussian blur and find the point that the grunge is blurred away but the face is still there: remember this number (~9px) and cancel the filter.
- Obs: For this to work well the second number should be about 3 times the first (I had used 3,3 and 10 before but doing this again it appears that maybe 3 and 9 would be even better choices);
- Now do the method described which uses the filters inverted, 9 for the high-pass, 3 for the blur.
Tomorrow I'll explain it better in the tutorial, OK?

thanks

Thanks Ro, you explained that pretty clearly, I have a much better understanding now of what details to pay attention to when eyeballing the filter preview.

megl, glad you liked it. That came out real nice.

Sometimes I'll lower the opacity a touch from the 50% mark, to leave just a hint of grunge. Otherwise the skin can end up looking too perfect!
But this is going to depend on what the image wil be used for.


(too perfect?)
