Manipulate your bokeh shape
This is a fun little trick. With a lens with low aparture, like 1.8 you can get realy blurred backgrounds. The blobby spots for lack of a better word, oh wait… it’s called bokeh, take shape from the lens blades. The more blades the smoother bokeh.
What if you could take all those little spots (Caused by lighter parts of your image) and make them any shape you wanted? Well you can.
Open the lens all the way up, as low aparture as you can get.
Find some black thick paper and cut any shape you like, try with a heart shape for example. The size of the cutout has to be smaller than the aparture opening so just check the front of your lens to see how big the hole is.
Stick the paper cutout in front of the lens and snap away and check out all those little bokeh hearts, cool eh?
