Start learning about editing your photography

By David Peters


The resolution of your computer's monitor can greatly affect the outcome of your photos. This is the amount of pixels there are on the screen. The more there are, generally, the better the quality of the images. Making sure you have a monitor that is suited for photo editing is an important part of the process. However, you must remember that certain resolutions are meant for certain sized monitors. A large resolution on a small monitor makes everything too small, whereas the opposite makes everything too big. Make sure you know what resolution your monitor is made for. The display resolution of a digital television or computer display typically refers to the number of distinct pixels in each dimension that can be displayed. Some commentators also use this term to indicate a range of input formats that the display's input electronics will accept and often include formats greater than the screen's native grid size even though they have to be down-scaled to match the screen's parameters. An example of pixel shape affecting "resolution" or perceived sharpness is displaying more information in a smaller area using a higher resolution, which makes the image much clearer.

One problem people face when starting out with digital photography is how to touch up raw digital images. Perhaps an image is slightly dark, perhaps it has to be rotated or cropped. Maybe some dirty spots have to be cleaned out and erased. Digital photos usually require some form of manipulation before final output, unless, of course one takes a perfect picture. The first step is to find an image editor. For beginners, a program that has easy, simple tools will do just fine. More advanced people can move on to more complicated programs. There are many pictures that you've probably taken that would've looked great except for the red-eye. Just about every graphics program has a red-eye removal, so that no matter what level your program is you'll be able to remove the red-eye. However, in order to prevent it in the first place, it helps to know what causes it. Red-eye is caused by the flash reflecting to the back of the eyes all the way to the retina, and the red comes from the blood vessels in the eye. Therefore, if you flash a light in the eyes of your subject, this will cause the pupil to contract, and then there won't be any red-eye.

In earlier times, you took your snapshots with your trusty old Brownie, removed the film cartridge and dropped it off at the drug store for developing. After about a week, you picked up your prints. What you got was exactly what the film was exposed to. No cropping, no sharpening, brightness or contrast adjustments were available unless you had your own film processing and print studio. With the onset of digital photography, it has become possible for everyone to learn and perform successful photo editing. There exists a plethora of digital photography software that allow differing levels of image manipulation. With a decent digital camera, a computer with a quality printer, and one of the many versions of photo editing software, you can produce stunning photographs. You can crop for closer views of your intended subject, darken or lighten the exposure, adjust the contrast, sharpen the image, change it to black and white, sepia, or grayscale. Add a good scanner and you have the ability to edit your old standard photographs. That old faded photo of you as a child can be brought back to life with a few clicks of your mouse. With the right software, you can place objects from one photograph into another. Create a montage of any person containing their pictures from birth to present. That beautiful old Ford you took a picture of at the cruise-in brings back fond memories?

When comparing traditional vs. digital photography one of the arguments may be the ease of use. In utilizing a digital camera it is simply a matter of pointing and shooting. The image is captured by the digital camera and embedded on the memory stick contained within the digital camera. Also, using the easy viewing screen on the camera, the photographer can instantly see whether the picture is what they wanted or if it needs to be taken again. In fact if the picture has movement or does not capture the image that the photographer wants, it is easy to delete the picture from the memory stick.

No Autofocus! Manufactured before autofocus became the norm, screw-mount lenses need manual focusing. This is less convenient, as it is done manually - often at maximum lens aperture - and then the lens is stopped down (more on this later) for metering and the shot. The autofocus system may help as the sensors still work and give an indication in the viewfinder, at least on Pentax cameras where a custom menu option enables the function. This gives a confirmation of correct focus while the manually focusing the lens, even though the camera is set to manual focus. Focus trap technique. Set the camera to autofocus, not the sports focus mode, so the digital camera will not release the shutter until the autofocus system has confirms the lens is focused. Then press down on the shutter release while adjusting the focusing ring on the lens. When the autofocus system detects the scene is in focus, it will release the shutter.

At times the subject of a picture is lost in the surrounding parts of a picture. If this happens, you can always crop your picture. This means cutting down the picture to a certain size. There are many ways to do this in terms of the size of cropping. In just about every photo editing program there is a cropping tool, and you can experiment with the size of the area that you take out of your photograph. If you don't like what you've done, all you have to do is click "undo."

One of the most recognized and utilized programs for photo editing is Adobe's Photoshop. From this software the term "shopped" was phrased. People who work with and view photography use the term to refer to photographs which appear to have been manipulated to show something that was not in the original photograph, to remove something which was, or when the appearance of a person or object in the photo seems to have been altered. For example, you find a picture of a group of famous (or infamous) people, then you replace the face of one of them with your own for laughs, you have "shopped" the photo. Other programs are Corel Paint Shop Pro, and Serif Photo Plus, to name but a few.
