Testing fix for Polaroid Type 600 yellowing

I've been scanning thousands of Polaroid Type 600 prints. (See the series Instance/Instants for some of these shots.) But a common issue with integral instant prints is that they yellow over time.

Prolonged exposure to daylight seems to mitigate the problem. I'm conducting some tests—crude, perhaps, but a good starting point—to confirm that daylight causes the yellowing to fade without compromising the original image.

Once I've got this fix figured out, I'll be able to make selections, then fix their yellowing and scan at high resolution.

More soon ...
