Finally, after much thought and research, you have decided on the choice of a digital camera model. It's time to check its quality before making a purchase. But how to check it, what to click, where to look and what else needs to be done before heading to the cashier to pay?
Instructions
Step 1
Check the shutter lag. Set the camera to the maximum picture quality, turn on the autofocus illumination, liquid crystal display. Give more "tasks" to the camera, and then shoot, paying attention to how quickly the camera coped with the task. If the screen turns off for more than a second before showing the finished picture, then we can conclude that it does not apply to models with a large shutter lag.
Step 2
Check the matrix for dead pixels. Turn off the flash, tuck the camera under the counter and take a photo of something dark, or ask the salesperson for it. If the lens cap is not automatic, take a photo without removing it. This shooting must be done at all manual exposures. Shooting in the dark will help to make sure that all the pixels of the sensor are in working order. If, when viewing a frame, colored or light dots appear, it means that there are dead pixels on the matrix.
Step 3
Check the zoom lens drive. While looking at the monitor of the camera, press down the zoom lever slightly. The picture should smoothly decrease and increase, and there should be no crunching and extraneous noise.
Step 4
Inspect the camera lens for lens defects.
Step 5
Check for blur around the edges of the frame. Set the camera settings and take 4 pictures of a calendar, poster or painting in such a way that the camera is parallel to the plane of the subject. The photo should be smoothly enlarged from the center to the edges of the frame.
Step 6
Check the alignment of the focusing system. Configure camera settings. Draw a cross on a piece of paper - a kind of "target" for focusing - and place it on the table. Take 6 shots of the leaf at a 45 degree angle from a short distance. At the same time, move the central focus point to the drawn "target". The photographs must be in clear focus in the target area.
Step 7
Check the camera electronics. Set Auto and Zoom to about midpoint. Take one shot of the darkened corner of the store with the flash on, and the second shot of the view from the window. Study them carefully and evaluate the sharpness in the center of the frame, color rendition, distortion at the edges of the picture, sharpness at the corners of the photo.
