Hi Clotaire, I got the same problem with alt right click for resizing brushes, did you solve the problem?
Salut Clotaire, j'ai le même problème que toi avec alt clic droit et j'ai lancé avec les droits d'admin mais rien, tu aurais une solution maintenant ?
About Muselet, from what I saw, it's a kind of oily effect, like the former hyperrealist painters in the 70's. So it's mainly Filters>Blur>Surface Blur or Smart blur, up to you (note that you can use the high pass layer effect before or after blurring to increase details and a little gaussian blur to get rid of the halo around edges or fix the halo by mask or brush if you have time) so small details only disappear. For the 'over' highlights, use plastic wrap on selected areas with a blending mode like screen and the filter plastic wrap, very low opacity on this layer just to reach the oily effect on highlights which are most of the time on hyperrealist techniques a glazing layer of white mixed with a little of the opposite color of the shadows. Here, you may add a drop of orange or yellow in the white if your shadows are blue, some orange, pink if they are purple and so on... To get the weirdness in shadows you can select dark colors, create as many layers as you need and work on curves and contrast but to go faster I use apply image, soustraction, invert and scale between 1,4 to 1,6 and the distortion between 100 to 150 depending of the image. They are not the same everywhere, they are illogical so use a soft brush with the color of the shadows on a colorburn mode and a very low opacity, use a layer only for this work so you can fix the problems if any. It darkens the shadows where you want the color you want. There is also an outlines effect like a drawing effect in these photos, edges are more visible, apparent than for a real photo. Use a background copy layer and invert it, Filters>Minimum>between 1 to 3 px, blending mode to color dodge, black & white and lighten red and yellow especially in a face not to see small details, again it's up to you. Use this outlines layer with very low opacity in a blending mode like soft light depending of the result you want and have a mask to erase unwanted edges. Well, I didn't try, so it's just an idea, if I got time I will work on it and send you a sample. If you like it I'll give you the 'recipe' I used.
