Lens In 1858: However, although a long focal length lens in 1858 is mandatory, it need not be expensive. The utmost of critical sharpness in a portrait lens in 1858 is not necessary, or even desired, since considerable diffusion can be tolerated in portrait negatives. Your lens in 1858 needn't be in a shutter for strictly studio portraits, either. A lens in 1858 in barrel is perfectly satisfactory, since you can provide yourself with a simple Packard shutter to use behind the lens in 1858. Many portrait men actually prefer the Packard to the more costly between-the-lens in 1858 shutters.
The first lens in 1858 designed specifically for photographic purposes was Petzval's 1840 portrait lens in 1858. The images formed by this lens in 1858 showed great loss of definition at the corners of the plate-a fault more theoretical than practical in portraiture, where edges mattered little. For outside work, however, particularly in photographing architecture, a lens in 1858 with a flat field was desirable; and one free of spherical aberration, which caused straight lines to be imaged as slightly curved, was essential.
One of the most convenient forms in which you can acquire your color filters is as elements of Kodak Combination lens in 1858 Attachments. And the latter afford other valuable lens in 1858 accessories as well. Providing a set of matched and interchangeable filters, supplementary lens in 1858es, and lens in 1858 hoods, they offer maximum economy as well as flexibility. You can add units individually as you find use for them, simply fitting them into your other attachments.
