With two DSLRs in my camera bag and a steadily improving photographic eye, today I decided it was time to stop overexposing my subjects and creating horrible shadowed images with built-in flash and I invested in an external flash.
The difference in picture quality is phenomenal. Granted, it makes for a heavier overall camera assembly and it’s not quite a portable, but if I know that I’m planning on taking indoor shots and want to create the very best lighting conditions possible, you won’t ever see me using the internal flash again.
If you want to step up your indoor photography game by several levels, spend a little money and get an external flash. It’s money well spent and if you plan on making money with your photography, it’s required equipment.
