Getting to know editing digital photography
However, newer LCD displays and such are fixed at a certain resolution; making the resolution lower on these kinds of screens will greatly decrease sharpness, as an interpolation process is used to “fix” the non-native resolution input into the displays native resolution output. The best thing about digital cameras is that it’s easy to take thousands of pictures. That’s also the worst thing about digital cameras. After you’ve owned your camera for a few months, you won’t be able to find that great picture you took a couple of months ago if your pictures aren’t well organized or named logically. Folders are the best way to organize groups of pictures, and the My Pictures folder is a great place to start. In your My Pictures folder, create a sub folder for each year: 2004, 2005, 2006, and so on. This might seem silly the first year you own your camera, but after five years, you’ll be glad you did this because you can go back to your 2005 folder and easily find a picture from a vacation you took that year. Arranging pictures by year is also helpful if you’re scanning older photos stored in shoe boxes or albums that you took before owning a digital camera. This is also a good way to start organizing the pictures that you currently have on your computer.
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.
Sometimes, clear lines that separate the images in the panorama may appear. It is possible to blend the lines so that they disappear. Select the Advance Blending option located at the right of the Photomerge window, then select Preview. Inconsistencies in color will be calculated by the program. At this point, the images will blend together. Photoshop will combine all the individual images for your panoramic into a single layer. If you select the Keep as Layers option it is easier to edit each image individually. This is a great help if one of the images is brighter or darker then the other images. You can select that image in layers and adjust the brightness for just that image. It is a good idea to save the layers as a .psd file so that you can always come back and correct any mistakes or make any changes later. It’s a real pain to have to redo everything from scratch just if you made a mistake or want to change something later. You can also distort the pictures so that the scene will look like it is in perspective. Choose the Perspective option on the bottom of Settings. You can also do this by choosing Set Vanishing Point in the Photomerge window, then click to an area in the panorama.
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.
