Blair Camera Company,
Advertisement for the No. 3 Combination Hawk-Eye Camera, 1903
| Similar to the Kodak No. 4 Screen Focus, the Blair No. 3 Combination Hawk-Eye allowed the photographer to swing the rollfilm up out of the way for critical ground-glass focusing before making the exposure. Theoretically, this was a major step forward - up to this point in rollfilm photography, the photographer had to estimate focus using a distance scale or more basic zone focusing. However, similar to the No. 4 Screen Focus, many photographers found this new focusing procedure cumbersome and as a result, neither model sold particularly well. |
