Bucket seating for plein air painting

I noticed in a photo of David Kassan's subway demo he is using bucket seating. I never thought about it before, but it is a great idea for plein air painting because you can use the bucket first to carry your supplies and then flip it over to use as a seat.  It would be cool to create a little cushion on the top for comfort and then a fabric insert to hold/easily remove your supplies.  Maybe the insert can be zippered on top too... I have an 18" inch grape juice/wine bucket that would be perfect to try this out with!

Painting a figure composition by my teacher Max Ginsburg

"Unemployment Line",  a work in progress by Max Ginsburg.

Here is an outline of how he begins painting a figure composition:

1. Conceptual pencil sketches.
2. Painting studies of each model.
3. Compositional pencil sketches based on the painting studies.
4. Place a one inch grid over the compositional study to be used which, in this case, is 4" x 8".
5. Stretch a canvas, 40" x 80", the same proportion as the sketch, and draw a 10" grid.
6. In charcoal approximate the position and size of the figures.
7. Paint, in a direct alla prima manner, each model as a loosely painted block in from life.  So far in this painting each model posed 3 or 4 hours.
8. When all the models and background have been blocked in the development of the forms and the composition will proceed, with the models returning for several sessions each.

2 week pose. Shadow coming in from the right not on actual painting. Can anyone recommend a camera that does not cause distortion for under $500-600?
