OK, freecycle came to my rescue. I was looking at enlargers last week. C700 with 35mm negative carrier, darkroom safelight, 4 in 1 easel, 3 packs of Ilford paper and Sprint chemicals...here is the question. Donor says the chemicals are about 1 year old...can I use them still? It has been a long time since I printed myself. Anyone have sage advice about the use of this enlarger? I hope to start with it tomorrow on some film I recently processed myself. Anyone use it for 645? TIA.
