From a fan ... Beck! Great to hear from you! It looks like you had a wonderful trip [to Ecuador and Peru]. I'm wondering, how do you do that effect where only one object in the photo is colored?
Excellent question, Yi-Hsin! I personally use Picasa to edit my photos – everything from a simple crop or minor colour adjustment, to converting images to black-and-white. It’s very user-friendly and easy-to-use :) For the black-and-white photos where a small dash of colour remains, I use the technique “focal black and white” – it allows you the option to choose how much colour you want to keep in (and in which part of the image). Whilst it’s never perfect, and I certainly don’t use it as much as I once did, it can have quite a dramatic effect on some images!
