Please give the name of the knob that works as a lens switching from near to far focus. It does not affect the focus circuitry of the camera as it is after the auto-focus mechanism. It only affects how your eye picks up the image. It works just like the device an eye doctor puts in front of you when checking your vision. That device has lenses of various concave and convex curves to adjust for nearsightedness and farsightedness. They adjust for an eye that can’t focus at a reasonable distance, such as for close objects like reading this text. That little dial on a camera typically has an adjustment range of -3 to +3, with 0 being nominal 20/20 vision, more or less.
Explanation
The knob that works as a lens switching from near to far focus, without affecting the focus circuitry of the camera, is called the viewfinder diopter adjustment. It functions similar to the device used by eye doctors to check vision, with lenses of various concave and convex curves to adjust for nearsightedness and farsightedness. The viewfinder diopter adjustment is used to compensate for an eye that cannot focus at a reasonable distance, such as for close objects like reading text. It typically has an adjustment range of -3 to +3, with 0 representing nominal 20/20 vision.Rate this question:

The size of the opening in the lens when a picture is taken is called what?
Explanation
When you hit the shutter release button of your camera a hole opens up that allows your cameras image sensor to catch a glimpse of the scene you’re wanting to capture. The aperture that you set impacts the size of that hole. The larger the hole the more light that gets in – the smaller the hole the less light.
Aperture is measured in ‘f-stops’, for example f/2.8, f/4, f/5.6,f/8,f/22 etc. Moving from one f-stop to the next doubles or halves the size of the amount of opening in your lens (and the amount of light getting through). Keep in mind that a change in shutter speed from one stop to the next doubles or halves the amount of light that gets in also – this means if you increase one and decrease the other you let the same amount of light in – very handy to keep in mind).
One thing that causes a lot of new photographers confusion is that large apertures (where lots of light gets through) are given f/stop smaller numbers and smaller apertures (where less light gets through) have larger f-stop numbers. So f/2.8 is in fact a much larger aperture than f/22. It seems the wrong way around when you first hear it but you’ll get the hang of it.Rate this question:

When choosing your ISO setting, which of the following do you not consider.
- A.
Light
- B.
Distance
- C.
Grain
- D.
Tripod
- E.
Subject Movement
Correct Answer
B. DistanceExplanation
When choosing the ISO setting you should generally ask yourself the following four questions:
Light – Is the subject well lit?
Grain – Do I want a grainy shot or one without noise?
Tripod – Am I using a tripod?
Moving Subject – Is my subject moving or stationary?
If there is plenty of light, I want little grain, I’m using a tripod and my subject is stationary I will generally use a pretty low ISO rating.
However if it’s dark, I purposely want grain, I don’t have a tripod and/or my subject is moving I might consider increasing the ISO as it will enable me to shoot with a faster shutter speed and still expose the shot well.
Of course the trade off of this increase in ISO will be noisier shots.
Situations where you might need to push ISO to higher settings include:
Indoor Sports Events – where your subject is moving fast yet you may have limited light available.
Concerts – also low in light and often ‘no-flash’ zones
Art Galleries, Churches etc- many galleries have rules against using a flash and of course being indoors are not well lit.
Birthday Parties – blowing out the candles in a dark room can give you a nice moody shot which would be ruined by a bright flash. Increasing the ISO can help capture the scene.
ISO is an important aspect of digital photography to have an understanding of if you want to gain more control of your digital camera.Rate this question:

Name a feature of a camera that allows you to adjust the exposure measured by its light meter. Usually, the range of adjustment goes from +2 to -2 EV in 1/3 steps.
Correct Answer
Exposure CompensationExplanation
You can adjust the exposure measured by the light meter by telling the camera to allow more light in (positive exposure compensation) or to allow less light in (negative exposure compensation).Rate this question:

A digital SLR camera lets you preview the photo you're about to take using the large LCD on the back of the camera. This ability is referred to as what?
Correct Answer
Live ViewExplanation
This provides you with a second way of composing your photos - the first would involve looking through the viewfinder.
A live view LCD is great for people who don't want to be limited to viewfinder composition, and enjoy taking photos from the hip, high up, or from odd angles.
The continuous image displayed on the LCD helps you ensure that you're getting the composition right, even when your eye isn't pressed to the viewfinder.
But hold on a sec...this "special" feature sounds an awful lot like the way every compact digital camera works.
It is, but adding a live view LCD to a digital SLR is not quite a simple as it sounds. Not all live view systems are created equal.
The main issue that plagues most live view systems is one of speed: autofocus is slow, and the time to take a photo is downright glacial.Rate this question:

Regardless of your memory card speed, a movie file can’t exceed what size?
Correct Answer
4GB
4 GB
4 GigabytesExplanation
This is due to file size on the camera but you can restart the move again provided you have a card larger then 4GB. For a 4GB card you can record a 17 min. movie. An 8GB card will record a 34 minute movie.Rate this question:

This function “freezes” the camera’s exposure settings, so that if the camera is moved from one area to another, the auto exposure system won’t change aperture/shutter speed values.
Correct Answer
AE LockExplanation
There are many situations where this may be useful. A photographer shooting a portrait, for example, might want to place the subject off-center. Taking a meter reading off the subject, locking it (along with focus), and then moving the camera to re-compose the subject means that exposure won’t shift if the background is lighter or darker than the subject itself. Another example might be a shooter taking a sequence of images, panning the camera from one area to another (following a moving subject, for example). If there are differences in the background or lighting, it’s possible that exposures will vary from one shot to the next. With AE Lock active, exposures would be consistent from shot to shot.Rate this question:

Cannon does a good job of making it easy to change the most commonly used camera settings. You can access many critical options by pressing the buttons on the camera body, and other require only a quick trip to the camera menus. To make the process even simpler, you can create your own, custom menu containing up to six items from the camera’s other six menus. Logically enough, the custom menu goes by the name “My Menu” and is represented by what icon?

To get the colors in your images as accurate as possible you should adjust what?
Correct Answer
White Balance
The White BalanceExplanation
Why would you need to get the color right in your shots?
You might have noticed when examining shots after taking them that at times images can come out with an orange, blue, yellow etc look to them – despite the fact that to the naked eye the scene looked quite normal. The reason for this is that images different sources of light have a different ‘color’ (or temperature) to them. Fluorescent lighting adds a bluish cast to photos whereas tungsten (incandescent/bulbs) lights add a yellowish tinge to photos.
The range in different temperatures ranges from the very cool light of blue sky through to the very warm light of a candle.
We don’t generally notice this difference in temperature because our eyes adjust automatically for it. So unless the temperature of the light is very extreme a white sheet of paper will generally look white to us. However a digital camera doesn’t have the smarts to make these adjustments automatically and sometimes will need us to tell it how to treat different light.
So for cooler (blue or green) light you’ll tell the camera to warm things up and in warm light you’ll tell it to cool down.Rate this question:
