View Full Version : Cast drawing question...

Hi everyone!

I haven't logged into this site for a while, so I'm glad to be back! :)

I've decided to start a long drawing of a plaster cast. The cast is a woman's hand and forearm - you can see a photo of it at http://www.giustgallery.com/sculpture-reproductions/detail/female-hand/item-610/

I'd like to use the sight-size method, and I've set up my drawing area as follows:
- the plaster cast is mounted on a wall at about eye-level
- my drawing board is on an easel that's placed immediately to the left of the cast (I'm right-handed)
- the drawing surface is parallel to the wall at a distance of approximately 1.5ft from the wall, or basically the depth of the easel's stand
- I've taped off the spots on the floor where I'll stand to draw and also the distance where I'll step back to compare my drawing with the cast

Everything appeared correct until I noticed one very interesting and disturbing thing: when I'm standing in the drawing position, or closer to the easel, I see all of the left side of the cast and a only portion of the right side; however, when I step back away from the easel to the position where I'll compare my drawing to the cast, I see much more of the right side of the cast than I did in the drawing position.

Since this difference in perspective when I change positions is obvious and unavoidable, moving back to compare my drawing to the cast means my drawing will always appear inaccurate because I'm seeing a different object in the comparison position than the one I'll see when I'm actually drawing.

Although everything I've read about the sight-size method indicates that this "step-back" comparison is critical to achieving an accurate rendering, how I can draw what I see in the comparison position when I can't see it in the drawing position? Am I misunderstanding/misinterpreting something about the sight-size approach?

Any advice or suggestions would be greatly appreciated!

Thanks in advance!

crucial to the sight-size method is that you look at the reference only in the stepped-back position. When again at the easel, apply -- blindly :( -- the correction that you identified at the stepped-back position.
Don't be discouraged when it takes time, half a day to put two(!) landmark points in correct position was not considered excessive for a beginner.

Here you have a link to Ben Rathbone where the method is fully explained. Arnoud is right.


Hope that helps
