Define SLR:
A digital single-lens reflex camera is a digital camera combining the optics and the mechanisms
of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film. The
reflex design scheme is the primary difference between a DSLR and other digital cameras. In the
reflex design, light travels through the lens, then to a mirror that alternates to send the image to
either the viewfinder or the image sensor. The alternative would be to have a viewfinder with its
own lens, hence the term "single lens" for this design. By using only one lens, the viewfinder
presents an image that will not perceptibly differ from what is captured by the camera's sensor.

Define CONTACT SHEET:
A contact print is a photographic image
produced from film; sometimes from a film
negative, and sometimes from a film
positive. The defining characteristic of a
contact print is that the photographic result
is made by exposing through the film
negative or positive, onto a light sensitive
material that is pressed tightly to the film.
A contact sheet is an arrangement of image
thumbnails in one document, an electronic
version of the contact sheets that are
traditionally created from film. Use them to
catalog images, such as the photos that you
back up onto DVDs, for easy reference and
identification.

About histograms
A histogram illustrates how pixels in an image are distributed by graphing the
number of pixels at each color intensity level. The histogram shows detail in the
shadows (shown in the left part of the histogram), midtones (shown in the
middle), and highlights (shown in the right part) A histogram can help you
determine whether an image has enough detail to make a good correction.
The histogram also gives a quick picture of the tonal range of the image, or the
image key type. A low-key image has detail concentrated in the shadows. A
high-key image has detail concentrated in the highlights. And, an average-key
image has detail concentrated in the midtones. An image with full tonal range
has some pixels in all areas. Identifying the tonal range helps determine
appropriate tonal corrections.
What adjustment layer do you use to access this graph?
You use the Levels adjustment to correct the tonal range and color balance of an image by
adjusting intensity levels of image shadows, midtones, and highlights. The Levels histogram is a
visual guide for adjusting the image key tones

Underexposed
Why do you use this specific adjustment layer to make adjustments in photoshop
Levels is a tool in Photoshop and other image editing programs which can move and stretch
the brightness levels of an image histogram. It has the power to adjust brightness, contrast, and
tonal range by specifying the location of complete black, complete white, and midtones in a
histogram. Since every photo's histogram is unique, there is no single way to adjust the levels for
all your photos. A proper understanding of how to adjust the levels of an image histogram will
help you better represent tones in the final image.
