Great tutorial! the only thing that trips me up is the lighting? is there a quicker way to add the appropriate lighting. I manually go in and color change things. I am just in the learning stages of Painter. Thanks for posting!
ok first of try using 'Image>Gradient Map' you can nicely set each value of your tone. then you can use masks to apply it to certain areas. Another good colouring way actually is with a blending mode -> Overlay. It's a great blend mode but you gotta understand it. Basicly if you use neutral gray (RGB128) you're not affecting, using lighter colours will lighten and darker colors darken. Then you can choose to use a color also (keeping in mind the previous) and paint where you want to add stuff. Hope that helps.
yup I used it for Dereliction, Lost Citadel and some other works. It's fast and works really well for reference. Be sure to play around with the 'field of view' which can give you the 17mm super wide angle look I use in many of my works.
