It is interesting to see that words like “snapshot” and “photograph” as well as “positive” and “negative” go as far back as Sir James Herschel. A really good tip I picked up in this reading is to use a split exposure to increase shadow detail. Apparently the way to do that is to pull the print out at halfway exposure time and to leave it in low light for five to ten minutes. Then finish the rest of the exposure time in the light box or sun.
