This was a poster job I did for a pediatrician many, many years ago. His name was Noah and his practice was called Rainbow Mountain.
This was the first job I ever did that taxed the capabilities of my computer beyond what it could handle. I only had 2 Gigs of memory and I was afraid of putting in 2 more sticks and potentially breaking the computer. I knew next to nothing about messing with hardware.
My process would be to buy a new computer and migrate all my hardware and data to that new machine. At this time, I didn’t have enough money to buy a new computer this time and I was too scared to fiddle with hardware in the middle of a job.
Since there wasn’t enough memory and Photoshop kept crashing. The same file would also crash Painter. I had 28 versions of the same file because I was backing it up constantly.
The only application that could handle it was openCanvas. openCanvas enabled me to paint and build it in layers without crashing. For that reason, I am loyal to openCanvas. I still use it to this day.
