So our neighborhood is having a Christmas lights contest and, since ours is relatively tasteful, one can be assured we will not win. At any rate, I thought it would be a good time to learn how to use my Nikon D90 and get some pictures of the lights. My hubby is a very experienced photographer so he tried patiently to explain ISO and shutter speed to me. It still doesn’t quite make sense but here goes: ISO goes as high as your camera will go – I set mine at 3200. Interestingly enough, the shutter speed varied – some pictures came out good at 1/10, some at 1/8 and some at 1/25 and lastly, be sure that the camera is in manual mode and the flash is off. We found the interior tree pictures came out best if surrounding lights were turned off, too. It was fun to change the speed and see what happened. Now if I could only figure out how to get the dang camera on and off the tripod…I’m pretty much hopeless when it comes to photography! If composition were the only factor, I’d have it made.
