This article deals with the relationship between aperture, shutter speed and ISO value. Only when all three settings are coordinated will you achieve the correct exposure.

The camera sensor records the image information and is therefore the most important part of the camera. There are different sensors in different sizes and with different resolutions (megapixels). I explain how these variables interact in the following article.

SLR or system camera, which is better? Each system has its strengths and weaknesses. I explain the fundamental differences in this article.

Do you remember physics lessons when optics and light were on the timetable? That was one of the few topics that should have been memorized, because when it comes to photography, this topic becomes important again.

The gradations in brightness between the brightest point of a subject and the darkest point are called the contrast range. In this article, I explain what this is all about and why the eye is superior to any camera.

When do I use JPG and when do I use the RAW format? Do I really have to decide and what are the advantages and differences? A comparison and my personal recommendation.

How do the different focal lengths differ from one another? Does a telephoto lens bring objects closer together, and why can you see more with a wide-angle lens? You can try this out for yourself with a simple experiment, even without a camera.

I mainly use the aperture to control the depth of field. Depending on whether the aperture is open or closed, I get different image effects. You can find out why this is the case and what results I can achieve with it in practice in this article.

Modern cameras support the photographer with various automatic programs, aperture priority and shutter priority – but when does which setting make sense? An overview of what is in a camera and how to make the best use of it.

Before I go into the different metering methods, I would like to briefly explain what actually happens during exposure metering, what is measured there and why this is important. It is obvious that light is measured during exposure metering, but what kind of light it is is more interesting. There are two types of light […]
