One of the mantra's of lomography is not to think, just to shoot. This is some good advice, though if I'm honest,my best holga shots have indeed involved a bit of thought.
It'll probably take a few rolls to get to know your model's particular quirks ie, how it vignettes, where the focal soft spot is etc. Don't be disheartened if you don't get the results you're looking for at first - perseverance is key.
Most holga's come with a 6x4.5 insert to shoot rectangular images, and 6x6 for square: use the latter, as that's where most of the holga's optical pecadillos become apparent.
May I ask what camera did you use on this? I'm looking photos captured using analog cameras, and right now I'm planning to make my first feature journal devoted to all analog users out there... Especially ones that using medium format film
perhaps you can give me some reference? thank you...
