This is “The Ultimate Bounce Card” by Peter Gregg. This guy sells hand made bounce cards and shows how to make and use them. I found it pretty cool to share your techniques and hand made equipment that everyone can make at home with a piece of white and black paper and a rubber band. Watch the video and make one ! You need this stuff.

For the test I used my new flash Nikon SB-600 without build in diffuser at 24 zoom. Flash was fired remotely by CACTUS V2s trigger. Photos was shot on my Nikon D80 with 18-200 zoom lens set at 24mm 60 f/4.2 .
Not long ago I bought a new flash Nikon SB-600 and a pack of color gels. I surfed the net for a solution how to mount gels on a flash, found some ways but my gels was too big for DIY mounting racks I found, so then I saw an article “DIY 580ex color gels printing diagram“, it inspired me to make a printing diagram for my flash. I spend some time measuring my flash head and draw a sketch in Illustrator. Then I printed it and tried to mount on my flash, it fits perfectly.
Not long ago I saw an interesting idea how to make a handy and simple grey card. All you need is an iPhone or iPod or any other multimedia device that can store images. Upload the gray card image to your iPhone and use it like a preset while you shooting your photos.
