I don't know if 1 stop over is enough to change the look of Portra. Half a stop won't be noticeable at all. Charts like these made me realise how overexposure with negative film is a bit of a red herring
Thanks! I'll definitely look into it. What about overexposing b/w film? I'm tempted to rate Trix at 200, seeing as I had satisfying results with Portra.
Mainly because I was afraid I may underexpose a shot, but I also like the look of a slightly overexposed Portra.
