Lovely light & colour ... the swan bathed in light
you know I knew nothing about PS until I started here, I used to get stuck so many times but with the help of others & just playing with PS on an image to see what each thing did you get used to it ...
a simple way to straighten your horizon is just click
select rotate canvas
then select arbitrary
you then tilt it either to the right or left in .25 --- .05 ... 1,2, 3 & so on till you get it level not hard just need to practice
I'm about always happy to help, just send me a message, I'll help if I can ... thanks Paddy
