Rhys, get yourself a better camera. The Praktica is notorious for this 'problem', and the problem is yours, not your local Jessops. All standard automatic processing machines for film always trim pictures, they never print full frame. The only way to print full frame is to find a lab with a larger mask and some time on their hands, and subsequently a higher price, unless they're based in the outer hebrides. Labs on the high street, including Boots etc.., work to time and price constraints. They have alot of work to produce and unfortunately too many members of the public expect professional quality prints for cheap as chips prices. In my experience my local Jessops does a good job with my work, and it always helps to build up a good relationship with the lab manger or printer. Alot of people are giving Jessops a hard time at the moment, but they are still way and above better than most of the competition... good luck with your problem!
