mF’s GIMP Lomo script that I mentioned already works a treat with the settings he suggested! It works fine in GIMP 2.2 and here’s an example to prove it! Daffodils pictured by the Ballincollig Bypass in Co. Cork a few days ago.
Pictured on the Grand Parade on a freezing cold evening a few days ago.
This is the first time I used the perspective tool to shuft a photo slightly because I wasn’t in the exact middle of the frame!
