Photographic problem situations

On the following pages you will find an overview of photographic problem situations in digital photography.

Out-of-focus images

The following article offers you a short overview of the possible causes for out-of-focus images. More information about the individual problems can be found in the articles in the respective subject areas.

Depth of Field

Depth of field defines the spatial depth of an image captured in sharp focus. It can be adjusted depending on the situation and creative requirements.

Aspect Ratio

In analog photography with 35mm technology, an aspect ratio of 3:2 was the norm (e.g. film format 24x36mm). Derived from this film format, classic image sizes 10x15, 20x30, 30x45 appeared.

Digital Zoom

The way a digital zoom works is comparable to enlarging an image section during post-processing on the computer. In both cases no further image information is available.

Dust on the Image Sensor

This problem primarily occurs on digital single-lens reflex cameras. One of the causes is changing the lens and the level of camera and lens cover dust attraction. Abrasion of the mechanical elements can also dirty the sensor.

Defect Memory Card

Photos disappeared? Just yesterday you were looking at the photos on your camera and now they are gone. The camera is unwaveringly refusing to reproduce the photographs, to store new images on the card and a notice appears saying “card error“ or it requests formatting.

Defect Image Sensor

Defect image sensors occur very rarely. Compact cameras tend to incline towards this problem. On single-lens reflex cameras this problem hardly ever occurs. Should you be confronted with this problem, contact your dealer.

Problems with camera display screens

Especially if the surrounding lighting is very bright, many photographers that use digital photography have trouble reading the camera’s screen as it often overpowers the display’s lighting.

Empty Battery

In analog photography, most of the modern cameras were already dependant on a battery to power light meters, film transport, shutters and autofocus. This dependency has grown more acute in digital photography.

Perspective distortion / Sloping horizon

If the subject contains parallel lines, it is especially important to hold the camera parallel to the subject. If the camera is tilted too far, perspective distortion can occur.
