Unless you are obscuring a really big block of text for the entire moment that you are PhotoReading the page, you probably don't need to worry about missing out. Also, since my index finger was starting to get a little raw from turning pages, I just went to the stationery store and bought a couple of those rubber fingertip covers that postal and clerical workers use. I got one for my thumb and one for my index finger. They take a few minutes to get used to , but so far they are an improvement.
