I used to hate it - and I mean, really hate it.
Now I rather enjoy it.
What changed? Two thing...
1. My workflow. I got myself a copy of Lightroom, learned about some of it's features and found that I could do the menial stuff tha bored me much quicker.
2. Time. In the past I would go out, shoot, get home, download, process. NO real break, just one fairly constant action. Now I give myself a good few hours before I even consider looking at my images. I enjoy the photography, so I get home and feel the 'photography glow' I get from going out and doing what I enjoy. OK, recently the glow has been because it's bloody cold out!
THen later on I make a pot of coffee and start work on my photos. Deleting the howlers, saving the quality duffers (For a thread in birds forum) and narrowing my shots down to a small number that are the best. To me this is very enjoyable and I can from there look at my mistakes and learn from them.
Processing my images is now part of the learning expeirence - I enjoy it.
