About Me and this Blog
Monument Valley |
My name is René Grothmann. I am a retired math prof, living in Bavaria, Germany. I am not a professional photographer. I do not intend to earn money with my hobby. If you see ads on this blog, they are coming from Google, the host of blogger.com. But as far as I know, Blogger does not spam with ads yet. I have also no affiliation with a camera maker or any other sponsor.
So, who am I and why am I writing about photography? Mainly, I write for my own fun. It has educational value for me. Writing and teaching is a good way to learn. It does also involve experiments in photography which helped me to understand more. If the blog is useful to you, I am happy to read a comment from you. But this is one of the billion pages in the web today, and it has very little reach. So, I write it mainly for my own joy.
I am not a native English speaker. This will be apparent often. I fix mistakes in English occasionally whenever I spot them. I am sorry for any misunderstanding caused by my wrong use of English.
Here some pages which I like to recommend.
- DOF and Bokeh - Explained
- Equivalence of ISO Noise on different Sensor Sizes
- Teaching Photography - The Basics
- Portfolio
You can download the pictures on this page, and use them for your own purposes. Of course, you must not use them professionally. If you use them on a public place, please cite me.
