What are the Brighten & Darken Enhancements?

These enhancements let you brighten or darken either a specific area of the face, such as the eyes or the mouth, or a section of the photo itself. They include the following:

What are the Stylish Effects Enhancements?

These enhancements let you add such enhancements as soft lighting, bronzing, classic looks, or shadows. They include the following:

What are the Basic Enhancements?

These enhancements let you crop or sharpen the image of your photo. You can also choose to remove “red-eye,” or "add a caption" that can either identify or describe your photo for future reference. They include the following:

What are the Resize/Rotate features?

These features let you resize the image of your photo to make it larger or smaller; turn it around, or adjust the colors.

What are the Resize features?

These features let you resize the image of your photo to make it larger or smaller. They include the following:

What are the Rotate features?

These features let you turn the image upside down, or rotate it around any number of degrees. They include the following:

What are the Adjust Color features?

These features let you intensify or reduce the color in your photo. They include the following:

What are the Artistic Effects features?

These enhancements let you add a variety of effects, such as sunburst, dusk, or water reflection. They include the following:

What is Auto Exposure Compensation? What’s its use in photography?

Exposure Compensation is a feature generally found on an auto exposure camera. If a photographer wants to either under expose or over expose the picture deliberately he can’t do so by simply changing the aperture or shutter speed on an auto exposure camera. If you stop down the aperture the camera automatically goes to a slower shutter speed keeping the exposure at the same level and vice versa. Exposure compensation will now come to your help. It’s actually telling your camera to make “error” in exposure setting. Old cameras have a dial on the top plate showing markings like +2 +1 0 -1 -2
Set the dial to desired setting e.g. 0 would not make any “error”, +2 would over expose by 2 stops and so on. Modern film based and digital cameras have a small button marked with +/- symbol. Press the button and turn the command dial to set exposure compensation to the desired value.
You generally need to compensate exposures under abnormal situations. If your subject is seen against a bright background then over expose it by one or two stops and if the background is too dark then under expose it by the same amount. You also need to operate exposure compensation if you want to bracket exposures.

What is colour temperature?

A general illumination contains three components of light-Red, Green and Blue. A pure white illumination is a mixture of these three colours in equal proportion. In fact pure white light hardly exists in reality. A light however white it may look to be, may not be pure white. Morning sunlight contains more red than blue and at mid-day it contains more blue than red. As the sun rises up in the sky slowly the proportion of red goes on reducing and that of blue goes on increasing. At around 10 a.m. the sunlight or average daylight is close to white. Domestic incandescent lamps deliver more red than blue hence look yellow and skylight contains too much blue. A human eye however can’t notice the difference in the colour of light and it always sees the world as normal in colouring even though it’s not normal. A film or an image sensor in digital camera on the other hand can notice even a small difference in the colour of light and renders unsought colours on final output if you fail to make proper adjustments.
As our eyes can’t detect the colour composition of a given light source, light is codified depending upon its colour composition. These codes are called as Colour Temperatures. Pure white light is assigned a colour temperature of 5400°K. Smaller colour temperature signifies more yellowness whereas larger number indicates more blueness in the light.
Colour Temperatures of certain light sources are as under:
Domestic Lamps - 2500° to 3000°K
Photo Floods 500Wt and Tungsten Halogen Tube - 1000Wt 3400°K
Morning/Evening sunlight - 4000°-5000°K
Average Daylight/Elec. flash - 5500°K
Mid-day sunlight - 6000°K
Overcast sky - 6500°K
Skylight - 7000°K
Films are balanced for a given colour temperature of light e.g. Daylight film is balanced for 5400K and can render colours correctly if used under the same lighting otherwise the photographs will show some colour cast. As the morning sunlight has lower colour temperature, the photos will show yellow cast whereas under skylight they will look bluish. Composition of light has to be changed by using appropriate filters if the colour temperature doesn’t match with that the film is balanced for. 80 and 82 series filters are blue in colour and raise the colour temperature of light whereas 85 and 81 series filters are amber in colour and lower the colour temperature before the light strikes the film. A white balance setting in digital cameras simplifies the problem as white balance can be set for a specific lighting either manually or automatically.

What is white balance bracketing? Some Digital SLRs offer this feature; please explain.

Bracketing is sort of trial and error method. White balance bracketing is similar to exposure bracketing. If you are not sure, take different photographs by varying the exposures with some under and some over exposed frames and select the best one finally. White Balance bracketing also works in the same fashion.
White light is a mixture of Red, Green and Blue colours in equal proportions but a pure white light hardly exist in reality. General illuminations however white it may look to be may sometimes contain more red than blue or vice versa. For instance sunlight in the morning and evening has more red hence is yellow and that at mid-day has more blue. Our eyes fail to detect small differences in the colour of light as they get adjusted to the illumination automatically. A digital camera if set to automatic white balance setting would also does the same.
A D-SLR generally has both auto and manual/custom white balance settings. In auto White Balance settings the camera's sensors detect the colour composition of available light and set the colour sensitivity of the image sensor accordingly so as to render a white surface as white in the final output. In manual/custom settings too the camera’s colour sensitivities are adjusted manually to reproduce a white object as white. However accurate the White Balance settings may be, the final output might show a little bias towards either red or blue. The white balance bracketing now comes to the rescue. Camera now takes three pictures, one as per the WB settings, second with image sensor becoming little more sensitive to blue and third showing a bias towards red (may not be in the same order). Now the photographer can select the best picture finally. Please note that when camera takes three pictures in a row, it cancels the bias towards red by setting higher sensitivity to blue and vice versa.

I am not able to understand why there are two marks, a green and a yellow, for aperture setting on my Nikon FM-10’s 35-70mm zoom lens. Which mark should I use for setting aperture?

A zoom lens generally has two speeds (largest aperture in terms of f number). Nikon FM-10’s 35-70mm zoom lens has two speeds 1:3.5-4.8 marked on it. When the lens is set to 35mm focal length, its largest aperture is set to f3.5 whereas at 70mm it changes to f4.8. As you mentioned, the aperture-setting ring on the said lens shows two dots, a yellow and a green. They are actually colour codes for setting apertures. If you observe carefully you will find that the focal lengths on the zooming ring are also marked in different colours. 35mm is marked in green whereas 70mm is marked in yellow. This has some significance. If you set f5.6 against green dot, aperture f8 comes against yellow dot. It means that if you are working on focal length 35mm which is marked in green, the effective aperture is f5.6 as it comes in front of green dot, but if you change the focal length to 70mm which is marked in yellow the effective aperture now automatically becomes f8 (appearing against yellow dot) even if you do not turn the ring. Many photographers unfortunately do not take this fact into consideration particularly while shooting with flash in a function like wedding and end up with some under exposures when they set focal length to 70mm. So if you intend to shoot on aperture say f5.6 then set it against an appropriate dot either green or yellow depending upon whether you shoot on wide or tele focal length. If you take your lens to 35mm wide, set aperture against green dot but if you change it to 70mm tele then do not forget to turn the aperture ring and bring the same aperture against yellow dot.
Some other camera lenses like the one 28-70mm found on Vivitar N3800, 28mm is marked in white whereas 70mm is marked in red. Now there is white line and a red dot marked on the lens for setting appropriate aperture. Automatic cameras like Nikon F55, F65, F80, Canon EOS66, EOS300V etc do not show this problem because the aperture changes automatically depending on the focal length.
