I found this lesson required a lot of patience but at the end I think it was really worthwhile. I used Staedteler H, HB and 2B pencils (have not yet been able to get hold of the Col-Erase due to the lockdown) on A3 Seawhite drawing paper.
I did make a mistake drawing the overall shape of the cast and initially drew the hair too high. I did fix it later but I think I used too much prencil pressure earlier and after erasing it left a tell-tale shadow of the original line that I could not get rid of completely.
I found the hair very tricky…the main problem being that I would lose my eye position on the photo after looking at the drawing and a few times I ended up drawing a completely different hair wave that the one I started looking at! I found the best way to combat this was to sit back and take a few moments break then focus on one part of the hair and keeping my eyes on the drawing as much as possible. Afterwards I thought it may be an idea to leave the mouse pointer at the position on the photo I was currently dawing…so may try that next time.
I still have trouble getting a good photo and I have used my Samsung phone and Andoid tablet. I have found the best place is on an inside widow sill which faces west and in the morning when the light is good. Even then the photos do not show up the subtle changes in value in a grpahite drawing and It would be great to know how others take their photos.
