I have got an old Practica SLR from the 70's great old cam. I meant that it looked under exposed as in not enough light for the shutter speed/f stop. Incorrect light metering etc. I usually spot meter off a mid tone for film (probably not possible with an old Practica or in that scene) and set my shutter/f stop manually. A fraction of a second later and you would have got the compo. Being heavily overcast may have added to the general situation. Some 400 film can be grainy and some can be quite smooth (dont know why) Different cameras seem to affect it too. In the third pic (half Seaking helicopter)I have had shots that have had that magenta cast in the cloud, but I dont know what causes it. Maybe someone else can shed some light (excuse the pun) on it

The Truth is Out There
