Few Tips on Image Playback
Ability to see the picture immediately after the shutter button has been pressed is probably one of the major advantages of digital cameras. If you're not satisfied with the quality of a picture you can reshoot if necessary or you can delete some unwanted pictures in order to free up some space for new images. Some cameras have the "instant preview" feature which is a programmable amount of time that holds the shot on the LCD screen for a short period of time, usually anywhere from 2 to 10 seconds. Others may require you to press the monitor display or to switch to playback mode to review previous images.
Here are some image-playback tips and techniques that you can use in your work or entertainment:
You can use your instant review function to check if the image quality satisfies you. So if there is any problem with the picture, you know it right away and have chance to reshoot it immediately. Once you have a number of images taken, you can easily view them one at a time, either as a grid of images or using a slide show format. In order to do this, you just need to switch the camera from shooting mode to playback mode and activate needed review options.
However, it is necessary to remember that LCD screen only gives you an idea of what an image is going to look like, but often doesn't show you all the details. For example, a photograph taken in a low-light situation can look very dark on the LCD screen. However, after you've loaded the image into your computer the situation can be easily fixed by simple brightness and contrast adjustments and you'll get a fully detailed image.
If you're making macro or close-up shots with a digital point and shoot, not with a digital SLR, it's a good idea to use the LCD monitor viewer for framing and composition. Working through the finder can cause in what is called "parallax" error: at close ranges the finder can result in the image being framed differently than you have expected.
The instant review function is a great way to check whether you are satisfied with the framing and subject expression. It also can be used to check the exposure to possibly rethink the way you made the picture. If something's not right - fix it for the next exposure.
Some digital cameras also have an "info" playback mode that displays the camera settings along with each picture. This allows you to see what you did when you made the picture and, if you're not happy with the results, use the information to help correct the image. A few digital cameras can display a "histogram," a graphic representation of the scene that shows you if the image is under- or overexposed. You can use this to correct problems in your next exposure.
It is great to have a digital camera that has an "info" playback mode that shows the camera settings along with every picture. If you're not satisfied with the quality of an image, you can use the information on the camera settings to avoid same mistakes in future. Some digital cameras can also show a "histogram," which is graphic representing the scene that shows you if the image is under- or overexposed. It can also be used for learning and avoiding same mistakes.
