Handling and Care of Fine Art Prints

The proper handling of prints is an important step in insuring optimal print quality and longevity. It is critical to not only pay special attention to how prints are treated after they are made, but also how the paper is treated prior to printing. There are several important steps you should take, and things you should know, to keep your images looking great.

Storage / Handling Of Paper

How you handle an unprinted sheet of paper is perhaps more important then how you handle a printed one. Once the ink has bonded to the paper, there isn’t much that can affect it, however, there are a whole host of issues that can prevent bonding, causing prints to rapidly fade and deteriorate over time. The most critical aspect of paper health is the storage of it. It is important to inspect the condition of the box and the location of which the paper is being stored in, as this will usually be a good indication of the condition of the paper inside. Try to purchase paper from a photo supply store that has a good track record and sells their stock on hand quickly. Paper that has been sitting around on a shelf for years probably isn’t in as good a health as one that has been recently produced. Almost all packages of fine art paper will have a date of production on it, try to find it and select the most recently made box you can find. Read more

Accessorizing Your SLR Camera

Sometimes, it’s the smallest thing that make the biggest difference. Adding a few simple accessories to your camera can not only help make it more usable, but help you to enjoy using it more. Two of the first things I have always replaced on every camera are the eyepiece and the focusing screen.

Eyepiece

The standard eyepiece that comes with most cameras is just short of pathetic. It’s really meant as a temporary solution, to prevent you from gouging our your eye against a sharp corner or scratching your glasses, rather then a permanent fixture. On Nikon cameras, the eyepiece is actually two pieces: a glass disk to prevent debris and contact with the prism, and a rubber gasket surrounding that glass. While it is possible to replace one and not the other, I always replace both.

At around $10,and probably the cheapest photography item you’ll ever buy, the Nikon DK-19 replaces the simple rubber washer with a full rubber cup. This cup can either be used extended, to block out light from entering while looking through the viewfinder, or folded back onto itself to act like the original washer, but provide extra protection. The other half of the eyepiece, a little more pricey at $25, but still worth it, is the Nikon DK-17A. This replaces the standard glass disk with a higher quality glass featuring an anti-fog coating. If you ever plan to use this camera anywhere near a cold area, the eyepiece is almost guaranteed to fog up without an anti-fog coating. This eyepiece does a perfect job at stopping fog, something that the original glass is quite prone to. Read more

Understanding The Activity Monitor

Found in the Utilities folder with the Applications, chances are you have probably opened it up once or twice for something. Its main function is to display all the current running processes, along with their memory and processor usage. What it also shows you is the drive space, RAM space, network activity, CPU activity, and disk activity to name a few things.

CPU – This panel will display all the information pertaining to the usage of the processor. The first thing you will notice when viewing the process list is that 100% isn’t the maximum. The way the computer calculates percents for processes is based on every core operating at 0 to 100%, meaning if you have two cores, you’ll have a total of 100% processing power, 4 cores 400%, etc. Contrast this with the summary (lower panel) which runs from a strict 0-100% scale, meant as an overview to the system, rather then a detailed look as is the process view. The “% User” which is green by default, indicates the percent of the processor that tasks that belong to you are using. These tasks include pretty much anything that opens when you log in, as well as anything you manually open or run. “System” includes things that load up when the system is started as well as processes that cannot be terminated and that are necessary to the operation of the computer. “Nice” is a bit more complicated. The Nice processes are those which are running under a scheduled order – that is processes that are given a priority, to either be executed ahead or behind others. You will usually see the Nice increase along with heavy multitasking actions, such as some Photoshop plugins. Read more
