The aperture in Photography is the iris of the lens. The size of the aperture determines how much light comes through the lens and can be balanced with how long the lens is open to make an exposure. The aperture controls depth of field, that is the depth of space that is in focus. The smaller the aperture the deeper this space is.
A photographer may want to control the depth of field using the aperture setting to make sure the background is or is not in focus. Selective focus can be a powerful tool in a photo. If there are subjects in the composition at differing distances a greater depth of field may be required to insure they are all in focus together. An example of this might be a large group of people for instance.
The depth of focus at different f/stops will vary per the focal lens and design of different lenses. In general it will be greater at a given aperture with a wider lens and shorter with a longer (telephoto) lens. Also the closer your subject is the the camera the narrower the depth of focus as the depth increases with distance. An extreme example is f/8 for a given lens may produce a focal depth of 2ft for a subject 10' from the camera, this may be only 4" when the subject is 2' from the camera and may be infinite (50'-infinity) when the subject is 60' from the camera. This property can be used in the design off your photo for practical or artistic purpose.
Because Aperture, shutter speed and ISO are tied together in determining an exposure changing the aperture may require also changing one of both of the other with some trade-offs such as a slower shutter speed which may result in blur due to movement (by the camera and/or the subject) or increased noise is the ISO needs to be raised significantly.

Where can one purchase an enlarger for use during photography?
One can purchase an enlarger for use during photography at any camera specialty shop. One could also find an enlarger on eBay or Amazon. Best Buy also sells enlargers.
Why do you always focus your enlarger at the largest F-stop before using your enlarger?
Becausea) the image will be at it's brightest, making it easier to focusb) stopping down will increase the depth of focus (not depth of field) and help eliminate any out of focus areas due to lens defect or lack of flatness in the paper surfacec) reduce/eliminate any vignetting that may occur in a lens of lesser quality that can be evident (in the corners of the negative holder area) when used at full aperture.
What is maximum aperture?
Maximum aperture is the maximum amount you can get a hole to open.
What determines the shallowest depth in field in photography?
The largest aperture which is the smallest number on the aperture ring/dial generally anything between f1.2 - f5.6 dependant on the lens and zoom. On most consumer digital cameras the more you zoom in the higher the smallest aperture becomes. eg. Lens at 35mm, widest aperture (shallowest depth of field) generally about f2.8 Zoom in and the largest aperture will reduce to about f5.6
What is aperture priority of digital camera?
Exposure, in digital or film photography, is determined by aperture and shutter speed. On a manual camera, the user selects both values.On an automatic camera, there are four possibilities:Manual mode. User selects both aperture and shutter speed.Shutter priority. User picks the shutter speed and the camera adjusts the aperture to ensure proper exposure.Aperture priority. User picks the aperture and the camera adjusts the shutter speed to ensure proper exposure.Program mode. The camera selects both values.

What is the meaning of the word enlarger?

What is an aperture membrane?
An aperture membrane is a section of enzine forming the base of an aperture.
What is color enlarger?
A color enlarger is a device used in photography to project and enlarge color negatives onto photosensitive paper for printing color photographs. The enlarger uses colored filters to adjust the exposure time for each color layer (cyan, magenta, yellow) to create a full-color image on the photographic paper.
What is an aperture on a shell?
"Aperture" means "opening".
What is solarization in photography?
It's when whites are turned into darks. A solarized image has to be in the developer for a short time until the image could be a little seen and then dried and exposed again under the enlarger. I've never heard of doing it this way and can't see how it would ever work for several reasons I won't go in to. The method, as I learned it and always taught it is as follows: with the negative set up as normal, under-expose the paper slightly and remove the negative from the carrier. With the carrier back in the enlarger to block excessive light leakage from the carrier slot, remove the easel and move the print to the developer tray. When the image first begins to appear, place the print in the water bath for about 10 seconds to arrest development. Put the wash tray under the enlarger lens with the print still in it and with the lens aperture stopped down to F16, turn on the enlarger for about 2 seconds and blast the print with the enlarger light. Place the print back into the developer tray and complete the print processing as usual. The effect for a given print can be varied by experimenting with the amount of initial image exposure, initial development and subsequent exposure to the bare light. Alternatively, a 20 watt light source from about 4 feet can be tried instead of the enlarger. The second enlarger exposure could be dimmed if necessary by using a strip of partly exposed and developed film or shortening the time. The exposure can be increased by increasing the aperture. The technique s properly known as the Sabattier effect, and provides better results with high contrast paper. The "silver" lines that are often created between the original dark and "new" dark areas are Mackie lines. They happen because a boundry is created between the first partly developed dark area and the second dark exposure area. Not much development takes place along the boundary line.
What is 'apature' a synonym for?
"Aperture" is a synonym for a break or a crack. "Aperture" is used in many modern day phrases such as camera aperture and of course, "Aperture Science" from the game Portal.
