Before you start using your Diana F+ you have to decide which frame size to use! It’s up to you to choose between two different square formats. With negatives in size of 46.5 mm x 46.5 mm you’ll get 12 shots and with the 42 mm x 42 mm frame, you’ll get 16 shots per roll of film. Insert the correct mask before you put the film in. The format can’t be changed while you’re shooting.
The classic shot that the Diana is known for often has vignetted and blurry edges. Those are lost or at least reduced when you choose the smaller format. Another effect is that the shooting angle gets smaller. Using the 75mm standard lens, the angle is about 44° (46.5 mm x 46.5 mm) or 40° (42 mm x 42 mm). Here you can see photos for comparison:
In a close distance the effect is a bit smaller:
Shots will overlap when you don’t insert the mask. This can result in impressive panoramas:
A large number of interchangeable lenses and accessories (sold separately or as a set) can increase the potential of the Diana F+ immeasurably. I have tested those possibilities for you! Keep your eyes open for my following articles in the series and make sure to read Part 1: The Camera.
