A strange topic title but I couldn't think of a succinct way of describing it. I spent many years in Southern Africa and my main system was based around 35mm format. I typically used 100/200 ASA film in both colour and b&w and this covered most situations from candid to motorsport photography. Three years ago I moved back to the UK. Until this weekend I have been taking photographs with tripod mounted medium format gear. I decided to get another 35mm SLR due to my slow reacting eyes and much faster young children. Anyway, yesterday I went out with the kids, camera and some HP5+. It was a sunny winters day but the difference in exposure, with similiar visible conditions, between the Southern hemisphere and the UK was quite startling. It's really the first time I've noticed it because it's the first time in the UK that I've been handholding a camera. Is it just me or is the sunny16 different in Northern Europe, and does one generally use a faster film when handholding a camera?
