I did not have any good experience with flash until I paid attention to studio photography at my office (It is an IT Company :P ). I even got a good picture for my Facebook profile picture. Earlier studio photos were only used as Passport size photo and Raashan Cards.
This weekend I was playing with my little cousin. We were indoor and she had a white balloon so I decided to use that as my flash diffuser. To my surprise I found a huge difference.
You can see for yourself that in the first photo, the balloon diffuser has made the light softer.
This was the balloon I used
Later I realized that exposure value equally matters with flash as with no flash. Look at the following photos.
First one is softer and there are less shadows and I think this is very important in taking portraits.
So my little play with flash was good and now I have more things to do while shooting indoor photographs. And the main thing is, I do not need to buy any professional equipment but just keep some white balloons in my bag and little air in my lungs all the time.
Happy Photography.. :)
