Back to portraits, using the same model as in the EOS-3 test from Nuts & Bolts No.8, the first portrait is similar to the one used in that EOS-3 test of the Speedlite 550EX but this time the light from the main flash has been reduced to 1:2 ratio, hence the reduced illumination. On the second portrait, the flash ratio from the main 550EX has been increased to 3:1 resulting in a more powerful (and almost washout) rendition of the modelís skin tone. In these two final portraits, flash exposure bracketing were used in conjunction with the E-TTL Wireless Autoflash System of the EOS-3. The photo on the left was shot with the fill-in flash set at 1:2 ratio and no exposure bracketing on the main flash. The second photo on the right, the placements of the two 550EX Speedlites were the same as the first photo but the exposure was increased 2/3-stops for the main 550EX. The result is a stronger exposure on the highlight. Notice the lighter rendition of the modelís skin tone compared to the first photo. Overall, the Canon EOS-3 when combined with a single unit of Speedlite 550EX is already capable of beautiful flash pictures each time. With the added benefits of the Wireless Flash System, the performances of EOS-3 and Speedlite 550EX combination will be further enhanced. Text & Photos by Philip Chong.
