[Coco] [SPAM] 128K CoCo2

Wed Apr 22 08:56:16 EDT 2015

Kip,

if you can, put the camera/phone on a tripod or at least find a way to set it down and/or steady it. When you zoom in or get too close to an object, even if it's in focus the movement can blur the image. You could also steady the camera and take the photo from a distance and then crop it in any photo processing software. If you crop a lot, be prepared for the image to get noisy/grainy and also for any blur from movement or bad focus to be exaggerated.

If you are lucky, some cameras actually have a macro feature. When you select that you can get the camera up close to the object. For macro shots don't use zoom (or use it very carefully). Salvador
