I once asked him why he bothered and he told me that someone had taught him, he was now teaching me and he expected me to pass it on. So Ratty, that's what I'm doing here, passing it on.
Your first lesson is going to be about image size, file saving, and getting it web ready. Every camera has a setting for image size. You must always choose the largest one your camera offers. If you camera only offers JPEG, choose the 3:2 setting and it goes without saying you are always and I mean always going to use the fine image quality setting. I can hear some of you now saying to yourself. Why should I bother to do that if I'm taking pictures for my blog and my camera offers a PC setting, isn't that what I should use? Beside when I use that setting, I can get so many more pictures on my card. No, it isn't. You need to start with most densely packed picture you can, always, the end, period. This way you do not lose any details. And having twenty good pictures you can work with is such better than two hundred lousy ones.
Now because digital photography, unlike film photography, has two pieces to it and both pieces are equally important, we have to talk about photoediting. For the sake of argument, I am going to use Photoshop Elements. I have both Elements and Photoshop CS4, but we're going to use Elements here. If you don't have Elements, I'll talk later about Picnik and Picassa.
Upload your photo into elements and immediately save it as a TIFF. Why should you do that? Because every time you make any changes and save a JPEG, you lose detail and you don't want to do that. You want to keep all the detail you can. Then because this is lesson one and not lesson twenty one, I want you to resize it to 1300 pixels on the long side. Then save it for the web. Use the JPEG setting and image quality maximum in web dialogue box, and you're done.
I took these pictures with my Nikon Coolpix P80 instead of my Canon 50D and pro lens, because not everyone has a DSLR, but everyone can take a great digital picture.
