Editing Digital photography the easy way

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.

When you want to auction off your last minute items, or you have set up an online auction shop, the most common place to do it is on ebay. Bidding online is one of the most commonly used forms of buying anything online. Pictures are often used to say a lot about a product, you want to make sure to get a picture. Here are few tricks of the trade: Take photos of different parts of your product and try different angles. Photographing your product from many angles helps add depth and avoid a flat online appearance. Pick one main overall shot of the item, but also use other detailed photos or different perspective shots. The more buyers can see, the more likely they will buy your product rather than your competitors. Once you’ve saved all your photos to your computer, you can optimize your pictures for online viewing. Make sure your images are saved as JPEG files and increase the compression so that your pages will download more quickly on a user’s computer. Also crop your photos so that it is composed only of your product, eliminating white space and making your product look better. Edit your photo. Adjust the light and contrast to improve on your original photo. Make your subject stand out by adjusting the contrast between the foreground and background colours. You can also make certain parts of your picture lighter or darker to improve the overall look. Once you’ve practiced photographing your products using these tips, visitors will have a better shopping experience and will be more likely to bid on your items.

Take the Saturation slider and slide it to the left until the skin color looks pretty good, or the best that you can get it without looking fake. Don’t worry about the other parts of the picture right now. Just concentrate on the skin color. We will fix the background colors next. Once you are satisfied with your skin color, click OK to close out of the Hue/Saturation window, and you will see your new layer above your original picture. If you notice though, the adjustment that you made affected the entire image. To get that back restored to normal, click on the layer mask part of the new layer, and grab your brush tool. Make sure that your foreground color is set to black, and you have a large enough brush so that you are not brushing the background back a long time. Now, using black, brush in the parts of the photo that you want to restore back to normal. I usually brush in the whole picture except the skin areas that I wanted to fix. This gives me the most realistic look. You are now done with the Photoshop tutorial on how to fix skin color in a picture.

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.

Sharpening is one of the most impressive transformations you can apply to an image since it seems to bring out image detail that was not there before. What it actually does, however, is to emphasize edges in the image and make them easier for the eye to pick out – while the visual effect is to make the image seem sharper, no new details are actually created. The first step in sharpening an image is to blur it slightly. Next, the original image and the blurred version are compared one pixel at a time. If a pixel is brighter than the blurred version it is lightened further; if a pixel is darker than the blurred version, it is darkened. The result is to increase the contrast between each pixel and its neighbors. The nature of the sharpening is influenced by the blurring radius used and the extent to which the differences between each pixel and its neighbor are exaggerated.

By adding a good scanner 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? Just insert yourself into the photo standing proudly beside the car of your dreams. Photo editing not only provides you with beautiful keepsakes of the people and places in your life; it can provide you with hours of fun and entertainment. Children giggle and squeal with delight to find themselves placed into unknown and exciting places.
