silver shade needs immediate protection from light. it's diffucult to handle, but it's worth it.
color protection works fine without immediate shading. some days ago I made 2 similar shots, one was returned without haste, the other left open to light in a room with good light but no sun. I cannot see any difference. it takes a good moment to develop. the shots are completely blue for about 15 minutes before the image appears within another 15 minutes. the colors are fine. grain is still an item.
it's a bit of the old polaroid magic in slow motion.
