Crop sensors mean a few things to photographers. It is very valuable for users who are looking to get more reach, as a lens with a maximum focal length of 300mm will get an astounding 450mm! This is especially useful when shooting wildlife, birds etc. It will be much, much more expensive to try to obtain the same focal length on a FX camera by purchasing a 450mm lens. However, the downside is that wide angle lenses do not go …

Most dSLRs in the market now can be roughly divided into 2 groups: those with crop sensors, and those with full frame sensors. Crop sensors are also known as APS sensors and are smaller than full frame sensors. Hence, in terms of the 35mm sensors, there is a “magnification factor” for the smaller APS sensors.

One tip to taking sunsets is to use the “Shade” white balance. When the sun is low, the light is much warmer (with an orange hue) than when it is high up in the sky. However, the human eye is able to adjust the colours that we see such that they do not look very different from other times of the day. With “Direct sunlight” or “Auto”, the camera may attempt to over correct at times and the overall photo …

The white balance setting is used to achieve accurate colour reproduction, or to remove unnatural looking colour casts from your photographs. Most of the time, the “Auto” white balance takes care of most situations, but in tricky lighting…

The benefits and drawbacks of shooting in RAW format as compared to JPG are:
RAW format has a higher dynamic range which allows you to recover lost highlights and shadows in post processing
White balance, sharpness, contrast, colour saturation etc can be adjusted and can be reverted back to their original settings without compromising image quality. Any changes made to JPG are permanent.
Chromatic aberrations (colour fringing) can be corrected when the RAW file is converted to JPG
Easier to keep the RAW file …

The function of Active D-Lighting that is built into many Nikon camera bodies is to help achieve photos with a more uniform image contrast. This is especially helpful in situations where your foreground is dark and background bright. Focusing on a dark foreground will mean that the background (for eg. skies) will be overexposed. Similarly, exposing for the sky will result in an overly dark foreground. This is where Active D-Lighting comes in useful.

The minimum shutter speed depends on a few things: the focal length of your lens, whether it has Vibration Reduction (VR) technology, and on the ISO value.
Ideally, the shutter speed should be…

ISO refers to the sensitivity of your camera’s image sensor to the amount of light present. Generally, the higher the ISO value, the faster your shutter speed will be, and consequently the increased ability to work in lower amounts of light. When do I increase the ISO? Is it better to use higher ISO values? What do I do when there is insufficient light?

The 18-55 standard kit lens has about 3x zoom. Its benefits are, it is wide and long enough for covering a wide range of photography styles, and its weight makes it easy to carry around. Some limitations include insufficient range and the unsuitability for indoor photography…

Primes lenses are lenses with fixed focal lengths. The minimum aperture values for prime lenses are normally lower than that of zoom lenses. Also, prime lenses produce images that are sharper and of higher quality.
