How do I take better photos? | Ask Jack

Lyndsay wants people to post better pictures on Facebook. Here's how to get the shot right on your phone or camera

So many people post pictures on Facebook with very advanced cameras, eg from iPhones. Alas, many do not crop their photos, the horizon is not horizontal, there are dark shadows " Some people do not even know the camera can face outwards: I notice so many selfies! I think a gentle article from Jack Schofield on how not to disappoint your friends with holiday pics would be wonderful. Lyndsay (via Facebook)

There are some terrible photos on Facebook, but I think the average level is very high. Back in the dark ages BC (before computers), I edited several photographic magazines and a partwork, You and Your Camera. Then, the quality of the average enprint, as enlarged prints were called, was extremely low, and you couldn't edit pictures unless you printed them yourself. Photos taken with small-frame film formats - like the 110 cartridges used by Kodak's Pocket Instamatic cameras, introduced in 1972 - could be dire.
