Digital Photography Tips and Techniques

In some shooting environments, flash photography is strictly prohibited. Often, the ambient light is so poor that the shutter speed becomes very low. In this situation, the photo can be easily affected by blurs caused by camera shakes and subject movement. 

If you are handholding a lens, the rule of thumb says you typically need 1/f (f is the focal length in millimeter) second of shutter speed. For example, if you are shooting with a 200mm lens handheld, you need about 1/200s or faster shutter speed to avoid most of the camera shake. This is for average people. Some one may have very steady hands, others may have especially shaky ones. If you have a lens with vibration reduction (VR), image stabilization (IS), or vibration cancellation (VC) functions, the speed requirement can be greatly relaxed. Often, you can shoot with up to 4 stops (or 16 times) slower shutter speed. Read More…

For some unknown reasons, Nikon decided to skip the automatic exposure bracketing feature on the D40 and D40X DSLR cameras. For people who are interested in high dynamic range (HDR) photography using D40/D40X, this is a convenient feature that is missing. However you can still do HDR photography without it using D40/D40X. Here are two ways of doing that. Read More…

If you are not sure what the differences are between “CMOS” or “CCD” image sensors, this Kodak article may help you to understand. Historically, CCD image sensors have superior image quality. However, CMOS image sensors have been catching up fast, starting from low end applications, especially in mobile phones, to high end applications, in DSLRs. Do you know who has the largest CMOS image sensor market share? Read More…
