Usually I don't upload single photos. I prefer to create sort of story in albums, when it is possible.

John’s Background Switcher - my flickr browser

On the end of 2015 I found Sagelight Image Editor. It doesn't leave traces in EXIF, that is why I'm writing about it. It is a brilliant software written by single genius. It is very fast and pictures change in real time when you use sliders - big part is written in assembler. For me the strongest point is ,,Smart Fill Light" for darker areas with 3 independent modifiers. If you know any software with at least 2 modifiers, please, let me know. Another key feature is ,,Smart Contrast". It increases contrast but only for medium values. Unfortunately the author suddenly disappeared from the Internet a few years ago... so I have to reinstall Sagelight every few weeks. For installation and uninstallation I use Revo Uninstaller Pro
