I have just started contact printing my 8x10" negs. When enlarging, I'm doing what Ralph Lambrecht in Way Beyond Monochrome calls "localized test strips", which means every strip is made from the same portion of the image. I'm trying to adapt this method to contact printig, bit I'm having a hard time figuring out a convenient way of doing so. For enlargements, I'm using the DIY test strip printer from the book: http://www.waybeyondmonochrome.com/WBM2/TOC_files/TestStripPrinterEd2.pdf This obviously doesn't work so well with contact printing. Has anyone here found a good method for doing localized test strips in contact printing?
