Scanning from slides

I recently bought a very inexpensive slide scanner, hoping to record some older work digitally. You get what you pay for. Below are some mixed media pieces.

Monkey Man, oil, varnish, lacquer on canvas, 48"x54" SOLD

Uproad, oil, shellac, photo emulsion on canvas, 60"x55"

Square, oil, varnish, photo emulsion on canvas, 66"x56"

Oil Lamp, oil, varnish, shellac on canvas, 72"x66" SOLD

Orbis Tertius, oil, ink, collage on two linen panels, 42"x84"
