Sony Alpha A900 Review

-



The Sony DSLR-A900's body is constructed from five main magnesium alloy sections, and includes sealing to reduce ingress of moisture between the body panels, as well as at the various control dials and buttons. The Sony A900 has a Sony Alpha lens mount that also accepts Konica and Konica Minolta glass. A large pentaprism sits above the lens mount, both dictating the camera body's workmanlike visual aesthetic, and providing a very large and bright TTL optical viewfinder with 0.74x magnification. The rear panel features a large 3-inch LCD display with 921,600 dot resolution, equating to VGA (640 x 480) pixel with three R, G and B dots per pixel. This is used solely for reviewing of images, as well as for menus and status display; the Sony Alpha DSLR-A900 doesn't offer live view capability. There's also a small top-panel status LCD which indicates remaining shots and battery life, as well as the basic exposure variables.

Bokeh and DOF (depth of field) tips

-
Image
What is bokeh and DOF? Depth of field (DOF), refers to the area of an image that is in focus. You have most likely seen images where the main subject is in focus, while the background is out of focus or totally blured. The area that covers the focused area is the DOF (depth of field). Bokeh on the other hand, refers to the appearance of the light that is seen within the blured part of the photograph. Bokeh and DOF are important to consider for photographs when you need the main subject to stand out on its own and not be lost in background distractions. Isn't Bokeh and DOF the same thing? No, bokeh and depth of field is not the same thing, although they do work together. DOF is seen in a photograph where there is an obvious focus area, set against a blured background or foreground. Bokeh on the otherhand, refers to how your camera lens renders the light that is seen within the blured parts of the image.

Portrait Tips

Here are some excellent potrait tips that you will learn when taking a shot. 1. Don't Just Sit There... Static portraits —with the subject just slouched there, or stiffly posed, are not terribly appealing. It generally pays to play director as well as photographer when you're photographing people. Don't just hide behind the camera; interact with your subject. Tell a joke, have a conversation, do something silly, or even tell the subject what to do. The results will be be much more interesting portraits, and the session will be a lot more fun for you and your subject. 2. Use the Right Lens The right lens for a portrait is the one that provides the desired framing at a distance that provides the desired perspective. For a natural-appearing "head shot," this would be a short telephoto (85–135mm range for a 35mm camera), at a distance of around 31/2–5 feet from the subject. Use a wider lens, and you have to move closer to frame a head shot, and moving closer will expa
