The resizing of a photograph is another commonly used tool today. Re-sampling is similar to resizing but is not as familiar to many.

Let’s take a look at the difference between the two.

Resizing changes the pixels while re-sampling uses an actual algorithm to adjust the picture to appear to not be blurry, fuzzy or blocked. Some of the pixels will be doubled when using resizing to enlarge a picture.With resizing some of the pixels will be removed when reducing an image resulting in some lines of the photo disappearing.

Re-sampling however uses algorithms to determine the new size of the pixels. When re-sampling to a larger size, color will be added as a result of interpolation. When reducing an image through re-sampling, the actual pixels will be re-calculated. A good image editor will have multiple algorithms for resizing and re-sampling options.

With all of the advancements in digital technology, taking and improving photographs is quick and simple. The photo-mat is a thing of the past with the image of our pictures being available in seconds on our digitals camera’s screen.

Even with all of the advancements in cameras, pictures are still not always free of mistakes. Now we can correct our photographs both old and new through digital imaging software that can be done easily by anyone wishing to enhance and improve their photos.

Here are a few problems almost always seen in pictures:

Blemishes and Wrinkles – Sadly, point and shoot cameras frequently magnify the flaws in our faces. But thanks to Photoshop improving photographs by removing blemishes, uneven skin tones and wrinkles can be done easily and quickly. No one will argue when their picture makes them appear 10 years younger.

Closed or Half-Closed Eyes – The camera flash can prove to be a problem for some people. The camera always seems to catch their eyes closed.� You can correct the closed or half closed eye with ease.

Unwanted People or Objects – Everyone has experienced the wrong person being in the wrong place at the wrong time in a photograph. Don’t get frustrated, get rid of them! You can remove the person as if he was never there to begin with.

Exposure Problems - Too much exposure in a photo and you lose detail. Under exposure and photos become too dark. Improving photographs with these issues are a little more complex to do particularly if the exposures are extreme, but it can be done. You can greatly improve your pictures by bringing out the details in it.

Digital photographs are something that are important to all of us. Most of the pictures we take happen once in a lifetime, which is why they are so very important.

From your child’s first steps to pictures of your family, photographs are very important. As important as they are, nothing is worse than losing them. This can be very traumatic and frustrating, especially knowing that you’ll never to capture the picture again.

Even though it may appear that the camera malfunctioned, all hope isn’t completely lost. There are ways that you can recover your digital photographs, even though you may not be aware of it. Most digital camera’s for instance, use smart cards that will store the information. To be on the safe side, you should always safe your photographs to your card, and transfer them to your computer the first chance you get - then back them up to a CD or DVD.

There may be occasional when your digital photos are not so simple to retrieve. It will be much harder to recover your photos if the camera itself has had hardware problems to occur, or if the smart card has become corrupted. Should this be the case, refer to the software or consult a professional repairman. In the instance of a malfunction, there is software available on the market created for the purpose of correcting digital camera problems. Normally this software can recover the photographs.

Digital cameras are something that most of us own these days, as they take professional quality photos. Anytime that it appears you have lost your pictures, you can turn to software and professional recovery services to get your pictures back. Your digital photographs are very important, which is why you’ll want to take care of them. Mistakes and disasters do happen though - which is why there are recovery services.

Graphics programs can be used to both sharpen and blur images in a variety of ways. Portraits often appear more appealing when softened, especially the background in order to make the subject stand out more. This is an example of shallow depth of field and can be achieved with a camera by using a large aperture, or artificially within software, by selecting the background portion of an image, and then blurring it. The red-eye effect, occurring when flash photos are taken and the pupil is too widely open (thus reflecting back the color of the blood-rich retina), can also be eliminated. Edge enhancement is an extremely common method used to make images appear sharper, although many discourage this believing the end result is less natural-looking.

Data compression is used to reduce file size and save storage space by many digital formats. Digital compression of images may take occur in the camera, or can be done in the computer with the image editor. Images are stored in JPEG format have already been compressed. Level of compression can be set by both camera and computer programs.

Some compression algorithms, such as those used in PNG file format, are lossless, meaning no information is lost when the file is saved. The JPEG file format uses a lossy compression algorithm. This means the greater the compression, the more information is lost, eventually reducing image quality or detail. JPEG uses understanding of the way the brain and eyes recognizes color to make this loss of detail less perceptible.

Raster images are stored in a computer in the form of a grid of picture elements, or pixels which contain the image’s color and brightness information. The image can be enhanced in many ways by utilizing image editors to change these pixels. The pixels can be modified as a group, or individually, by the complex algorithms within the image editors.

Bitmap graphics editors are often used to alter photographs and other raster graphics. However, vector graphics software, such as Adobe Illustrator or Inkscape, can be used to create and change vector images, which are stored as descriptions of lines, Bézier splines, and text instead of pixels.

It is simpler to rasterize a vector image than to vectorize a raster image. How to vectorize a raster image is at the center of much research in the area of computer vision. Many people prefer vector images because they are easy to modify, and contain descriptions of the shapes in them for easier rearrangement. They are also scalable, being rasterizable at any resolution. To rasterize a vector image is simply to render it, while scaling a raster image up entails guessing at data that isn’t there. Even the scaling down of a raster image involves conjecture unless the scaling factor is an integer.

Underexposure in photography is one of the things you can count on as you become more involved in photography. You can set your camera just so for the environment around you, and still end up with something that is too dark. Using any photo editing software you can easily fix this problem. Here I am going to show you how to do it using Photoshop and it is a pretty easy fix.

If you do not have Photoshop installed on your computer you can easily go to www.Adobe.com and download a 60 day trial version. It is a great way to become accustomed to the program without a huge initial expense on your part.

After you have loaded your photo in Photoshop, you will first want to create a duplicate of your picture. Select Layer/Duplicate Layer from the menu bar. Now you will want to select Layer/Layer Style/Blending Options. Select “screen” from the Blend Modes drop down menu.

Immediately you should see a lightened picture. Depending on how dark the picture is, your photo may now be exactly as you want it.

Using a digital photography green screen is easy. The screens are used in both still photography and videos although it’s more common in video photography.

First off, you need an actual green screen. Despite the name, this can be either green or blue in color. The choice of color will largely be dictated by what you are photographing as you want to make it easy for your software to isolate the intended image with you.

Purpose made green screens are readily available from around $20. You can look for them in places like eBay, Amazon or your local photo store. Alternatively, you can make your own from fabric or even by painting a roll of paper. So long as the color is consistent, you’ll be fine.

Next up you need to make sure that you have good lighting for your digital photo. This is especially useful when you come to edit your pictures as extra shadows can confuse any automatic software options that you choose.

Although you can buy expensive lights, you’ll probably find that you can get very good results with just a couple of fluorescent tubes. Place them both upright, in front of your subject and to either side. This way any shadows should be canceled out.

Then take your photographs.

Once you’re happy with these, the time has come to edit them and put in a new background. So your "talking head" shot now shows you in a news studio, in front of a street scene, or just about anywhere else you choose.

Much will now depend on your photo editing software.

At its most basic, you will need to trace round the outline of your chosen image. Programs like Paint Shop Pro and Photoshop have tools that will help you to do this. But it may still take a while to tweak the places where the automatic software recognition program isn’t as accurate as you may like. This is where the contrast between the green screen and your subject matter comes in handy as it gives your chosen software a much better chance of doing a good job with as little of your help as possible.

Once you’ve got your image selected, you then need to use another option to digitally "lift" the image and then drop it onto your chosen background. Again, this will vary with your software package but providing you can get the software to just copy the selected area, you’ll be fine.

It may pay you to practice doing this with a simple shape such as a rectangle or a circle so that you don’t waste lots of time tracing round a complicated image only to find you press the wrong key at the wrong time. It’s at times like these when you’re grateful for Edit Undo options but personally I wouldn’t rely on them one hundred percent.

It’s then a relatively easy matter of dropping your carefully cut out selection on to the new picture. So you can then pretend to be talking to people from in front of the pyramids of Egypt or anywhere else you prefer.
