I am a very active member on Philmug forum, I really love to learn from wonderful people about photography techniques, tips, advices, etc. I found an interesting forum about cheap photography trick by Krist Menina.
He said : " I was gonna try the vaseline hack from this Photojojo blog and I bought a slightly cheap UV filter for it. But then it's not easy letting go of a brand new filter (and throwing 400 pesos in the air) in case, it would be permanently damaged. Fortunately, I found something real cheap to get the same effect: the plastic cap of a cotton buds container (30+ pesos). I got photos that have a lomo-y look to them even though they we're taken off a Lumix GF1. "
Krist is a genius! Check his photos on Flickr account. So I tried to experiment my photography, it was so fun! Amazingly, there are many different effects: dreamy, lomography style, Holga-style, pinhole effect, scratchy / vignetted effect, etc. Here are my shots.
