I have a problem, and i would greatly appreciate any help if you could spare some time. I've always had great trouble with drawing from life or photographs in correct proportions if I want to make the drawing larger or smaller than the 'reference'. If I just make a 1:1 sized drawing/copy i'm quite OK, but any rescaling simply won't work out for me. If i try to do that, my brain somehow automatically switches back to the reference size after some strokes, and i just am unable to relate the size of the things i see to the resized things i (want to) draw. I guess the standart answer would be "Well, it takes practice!", but i really have tried to practice this so much already (which means hundrets of failed attempts) , yet i still can't see real progress regarding this matter. Since proportions are about the most fundamental thing of any drawing, i am really am stuck right at the beginning which is nothing short but frustrating as hell. So I am wondering, is it just me, or has been drawing at a different size such a hurdle for many of you? Any ideas what I could do about it? Thanks a lot for your help and sorry for my clumsy english!
