I can't add much that hasn't already been offered up as advice. I am mostly a consumer of photos; I use what photo's people send me or the photo's I can troll for online. I do own five digital cameras of various ages, makes and models; the most expensive one was around $300 in cost, but I usually don't remember to carry them. I have become reasonably adept at fixing photo's, my favorite software being an older version of Adobe's Photoshop Elements, their "Fix Everything" button does an amazing job.
I do have two tips:
- Don't sweat the small stuff. This has already been mentioned many times. You don't need the latest, greatest camera. You don't need the greatest picture. If it does a good job of illustrating the point of the post - go ahead and use it
- CROP your photos. Cropping a photo is just like another layer of zoom-in for your bag of photo tricks. It can bring immediacy and interest to, what was before, a blah photo. And you have lots of latitude. I crop my header photos to 1150 pixel width which just fits on the screen of my older laptop. Considering that most modern digital cameras are producing photos with something like 3000 to 4000 pixels in both directions, you can throw away a lot of your photo and still have something eminently serviceable to put on your blog.
