Bending The Rules
A Third Reference • Polarizers Plus • Monitoring Your Monitor • Who Took My Pictures? • OversaturationMonitoring Your Monitor
Q I'm an old salt in photography (40 years), and I just discovered the wonderful world of digital. I know how to take sharp images, and when I preview them in the camera, they're sharp, but when I transfer them to my computer, they're soft. The ones that I enhance and print are sharp. Someone told me that my monitor has a card and it's probably the wrong one to view my photography. Could that be true? It's driving me nuts to look at soft images on my monitor.
A The card that controls the images on your monitor resides in your computer; it's called a graphics card. The graphics card needs to be compatible with the monitor you're using. Usually, the computer and monitor are purchased as a set, and the graphics card is already configured optimally for the monitor. But if your computer and monitor aren't the same age, they may be incompatible.
Your monitor may be incapable of resolving the images you're trying to display. If it's an older model, it probably has lower resolution than needed. If you have a new monitor, but an older computer and graphics card, these may not be up to the task of supporting the resolution capabilities of the newer monitor.
If the age difference isn't the source of the problem, determine the resolution of the monitor (such as 1024x768 or 2560x1440) and the capability of the graphics card, which would be expressed in similar numbers within the specifications for the computer. Graphics cards can be upgraded to match newer monitors.
Who Took My Pictures?
Q I removed the memory card from my camera and took it to an automated print kiosk to have prints made of a friend's party. The pictures were the last of about 100 images on the card. When I put the card in the first print machine, the last 12 or so images were gone. I tried three different machines about four times. Gone! So when I got home, I downloaded them into my computer and there they were. What could have happened to them? The CompactFlash card is a SanDisk 4 GB Extreme IV. This is very puzzling! Should I not use this card again, or should I format and reuse?
A Every camera has a numbering system for image files. When a maximum number is reached, the camera creates a new folder for the next set of images. Different manufacturers and levels of camera bodies have different file management strategies. As an example, a DSLR may begin a newly numbered folder after 999 images, or may simply start over again with duplicate numbers at 9,999 images. Some DSLRs offer the photographer the capability of starting a new folder with each insertion of a new CF card or, even better, you can create your own folders and organize images at capture into a folder of your choosing. You can learn more about creating folders on some Canon DSLRs at www.learn.usa.canon.com/resources/articles/2011/eos_quicktip_creatingfolders_memorycard_article.htmlp.
