In Photoshop > Preferences > Scratch Disks. If we want a cheap and easy Photoshop scratch disk we can simply plug in an external SSD drive and specify it Your scratch drive should be very large and it should be on its own dedicated drive. To eliminate these problems and gain performance, Without sufficient access to fast RAM, Photoshop will hang, pause, delay, spin. Besides, sometimes we want to shoot at wide apertures. To get around these problems, we can shoot at small apertures and rely on increased depth of field to getĮverything in focus, but that's not an ideal solution since image quality starts to degrade once we See Cinema Lenses: What Are You Paying For? One reason that cinematography lenses are more expensive than still lenses ? For optimal results it's best to focus at actual taking aperture, which isĮasy with manual-focus lenses. This is determined by the optical design of the Budget-priced lens adapters and extension rings can causeĪperture moves the point of sharp focus closer and farther. The best and return the others to the retailer. To avoid de-centered lenses, some photographers routinely purchase several samples, keep A misalignment of internal elements has been overlookedīy quality control.

This is determined by the optical design of the lens, not manufacturing. It extends forward from the lens like a curved wave front. May focus sharply in the center but the edges will focus at a different distance. The most stable inkjet images are monochrome, printed with Carbon pigment on rag paper.They discolor and disintegrate over time. Inkjet papers are composed of a backing layer and an inkjet receptor coating. Inkjet prints are subject to damage by water, light, atmospheric contaminants and framing materials.For longevity tests not sponsored by printer manufacturers, see the Light Fade Test Results at Aardenburg Imaging. Typical longevity testing is performed under controlled humidity and lighting conditions that are rarely encountered in the real world (read this report from Wilhelm Imaging).Every combination of printer, surface and ink has its own fading profile: each color fades and shifts at its own rate.There is no official standard for "noticeable". Experts define image permanence with regard to how long it takes for colors to fade and shift by a "noticeable" percentage.Galleries and photographers who sell them (and the companies who sell printers, paper and ink) may be reluctant to emphasize this point but ironically, the best way to preserve inkjet prints is to store them in total darkness at low temperature and humidity.Images printed onto metal and glass are also subject to fading and discoloration. Like the countless millions of Kodak and Fuji prints produced over the decades, inkjet images start to fade and shift as soon as they roll off the printer.
