The ability to review your images on the spot via your LCD screen is priceless. If you are new to photography this is a fast and inexpensive way to shoot multiple shots to quickly achieve the desired results.
You can take as many pictures as you want with no extra cost. There are no worries about using up your expensive film. This means you have a better chance of capturing that perfect shot, something you could have missed if you were too concerned about saving film.
If you are using a digital camera, at some point you will be uploading your images to a computer to view or edit them. This affords you full control over how your images are processed and edited, via many different photo editing software programs. Using film regrettably leaves you no choice but to leave most of the processing up to the lab.
It is easier to make professional looking images with less expensive digital cameras than it is with less expensive conventional cameras. The reason is photo editing programs can significantly improve your finished product.
With film you are forced to develop all your images before you even know which are good enough to keep. Digital cameras give you a huge advantage by allowing you to view your images on your computer, then deciding which ones meet your standards. This lowers your printing costs considerably.
Another practical and fun advantage is that in just a few steps you can easily share your photos with your friends, family and the public.
Even though the rare purist will not compromise his standards and will faithfully hold true to traditional photography, digital photography for the majority just seems to make sense.
