I need help! I feel like over time my ability to make a good exposure on white backgrounds is getting worse rather than better. I shoot product photography of DIY projects that I design for my blog (idlehandsawake.com). My problem is that the white backgrounds almost always end up reading blue/green and pixellated in some areas. (In this example it's the top left corner and left side of the image). Shooting data: Canon 50D EF 50mm f/1.8 II 1/125 sec; f/5.0; ISO 400; Manual; Spot Metering RAW I'm including the SOOC file and edited file of the same image, as well as a shot of my typical setup (very basic). I use the histogram on my camera to make sure highlights don't get clipped. Usually I shoot at a lower ISO with a tripod, but for this shoot I was in a rush so I cranked it up so that I could shoot handheld. But I have this issue regardless of ISO settings. Any indication as to what I might be doing wrong or how I could fix it?
