“Digital cameras are a boon to genealogists. Before digital, using a film-based camera meant waiting for the pictures to come back from the processor before knowing whether the desired image was captured. What a shame if the tombstone inscription picture taken on vacation was washed out with too much flash and you didn’t know it until you returned home and got your film back from the drugstore. Using a digital camera means you can take dozens, hundreds, or even thousands of images without the cost of film or developing; better still you can check the quality of each image as soon as it’s shot. And, if you’re dealing with a lighting situation that makes getting a good shot impossible, you can still use image editing software to save the photo.”
