Ok- I am fairly new to photography so I'd love some advice. I have a backdrop (white muslin), a Nikon D60 and 2 umbrella lights (silver lining) for inside baby/kid photo sessions (just for fun/not a business)....and I cannot seem to get enough light in my picture. When I use my speedlight flash my pictures get washed out. Any suggestions on what kind of lighting I can add to improve the brightness of my shots??? THANKS!
