I miss my Holga. A lot.
Today, I was out of town and had a few hours to kill. I happened to have a can of tuna in the car (don't ask) and I had an idea. A bad one.
I drove to a camera store and bought a UV filter (first time in my life, by the way).
I opened the can, and started to get some of the oil with my finger. I spread it all over the filter, and then I screwed it on the lens of my Sony a6500.
The results are promising. Not exactly a Holga look but very dreamy and surreal.
I still need to play with this a bit more, using vaseline instead of oil next time.
I'll keep you updated.
