That scanning trick with a cheap LED light pad saved my underexposed rolls
I shot a whole roll of Portra 400 at a dimly lit punk show last month. Everything came out looking like mud. Before tossing them I tried putting the negatives on a $12 light pad from Amazon and scanning with my phone at max brightness. It pulled out details I had no idea were there. Faces, stage lights, even some smoke in the air. Anyone else rescue garbage shots this way or am I just lucky?
