Now that my patience for film photos has waned, mostly due to the sheer cost of it - medium format is essentially a quid a shot - I'm liking this little photo-grunger-upper application called Poladroid. It's Mac-only for now, but they're promising a Windows version soon enough.
Here's the original photo, Emma outside the Old Bell Tavern in Harrogate (which by the way, is a fine pub...):
...and here's the vignetted, messed-up Poladroid-ed version.
So it's a bit daft and all and dead retro-y/regressive, but when digital seems so clean, it's understandable why people are going back to these effects. I half wonder whether in 40 years time todays' youth will be tightly JPEG compressing their photos down to get that shitty, blocky phone camera look.
