My activities here change with time. I improve images and can remove watermarks, clone parts of the image and reduce regular noise (FFT filtering); I also draw crystal structures from CIF files and can provide CIF files for many solids. More information can be found on my en.wiki user page. I review and tag newly uploaded images for copyright violations – please don't take it personally, copyright rules are difficult and often annoying; they differ across various wikis and other websites, but we must follow them. I used to be fluent in Dutch and could speak some French and Spanish, meaning I can still understand a bit of these and a few other European languages, but I will probably reply in English.
