SLR stands for "Single Lens Reflex", which means you are viewing your shot trough the lens and seeing it as it will appear on film.

A 35mm SLR is a single lens reflex. that means that you are looking at the actual picture through the lens. When you take the picture the lens snaps up out of the way to allow the light to hit the film. Other 35mm, whether focal plane (old and not sold anymore) or point and shoot, cannot give you the exact picture through the viewfinder but rather a best guess on what it will look like. this works fine unless you are doing close-ups.

The single-lens reflex (SLR) is a type of camera that uses a movable mirror placed between the lens and the film to project the image seen through the lens to a matte focusing screen. Most SLRs use a roof pentaprism or pentamirror to observe the image via an eyepiece, but there are also other finder arrangements, such as the waist-level finder or porro prisms.
Cross-section view of SLR system.The shutter in almost all contemporary SLRs sits just in front of the focal plane. If it does not, some other mechanism is required to ensure that no light reaches the film between exposures. For example, the Hasselblad 500C camera uses an auxiliary shutter blind in addition to its in-lens leaf shutter.
The cross-section (side-view) of the optical components of an SLR shows how the light passes through the lens assembly (1), is reflected by the mirror (2) and is projected on the matte focusing screen (5). Via a condensing lens (6) and internal reflections in the roof pentaprism (7) the image appears in the eyepiece (8). When an image is taken, the mirror moves in the direction of the arrow, the focal plane shutter (3) opens, and the image is projected in the film (4) in exactly the same manner as on the focusing screen.
This feature separates SLRs from other cameras, as the user sees the image as it would be captured. This aids in accurately knowing the image beforehand.
Since the technology became widespread in the 1970s, SLRs have become the main type of camera used by dedicated amateur photographers and professionals

SLR (or Single Lens Reflex) primarily means that when you look through the viewfinder, you are looking through the actual lens. a little mirror hangs down between the lens and the film itself, and when you press the button the mirror retracts just before the shutter opens.
In most other traditional camera arrangements, the viewfinder is a completely separate lens, so you aren't exactly seeing how the photo will look.
Also, most SLR cameras allow full control over the aperture, exposure, etc. whereas a consumer camera is more likely to be set to fixed values. This makes a SLR harder to use but often more desirable for the expert user.

SLR stands for single lens reflex, basicaly this means the view you see is actualy through the lens that will expose the film instead of you viewing through a view finder lens. The advantage of the SLR is really only apparent on close up shots where a phenomina called paralax can occur because in a two lens camera ( non SLR) the view of the lens and the view finder are slightly off set causing the framing of the picture to come out different.

SLR means single lens reflex - which means you look thru the real lens of the camera - so what you see is what you get - it works by using a prism and a mirror which move out of the way to expose the film in the backplane of the camera.
other 35 mm cameras use 2 lenses -twin reflex or more popular and generally less expensive just a view finder camera which give view of an approximation of what you will get on film

Single Lense Reflex - nearly all 35mm cameras are set up to SLR whether it says so or not. Through a series of mirrors it allows you see through the view finder exactly what you are taking a photo of.

Suffice to say---the SLR stands for --single lens reflex--and this tag is given to the type of 35 mm that accepts lens changes --one at a time of course---cameras not in this category are usually what is called---rangefinder 35 mm's---they are the ones that come with a particular lense perminently mounted (usually a 50 or 52 mm lense)---hope this clears this up for you

SLR is a single lens reflex, it has a shutter as opposed to a point and shoot type camera. You control the aperture, shutter speed, etc.
35 mm refers to the film not the camera.
