Arches make some really nice watercolour painting paper.
Thanks, perhaps I should post something (tomorrow) on art images and copyright law which unfortunately, is far more varied and complex, particularly internationally than @ChrisMann suggests. But still fun and thought provoking 'cos one can dip into aesthetics, creativity, art history and all sorts of other fields.
I so agree!
Another aspect I love about post-processing is using an “emboss” filter to alter and accentuate the texture of the image - works particularly well with wood and with stonework. This is what I did with the Crowhurst Yew.
Also, I love Hahnemuhle matt papers for printing such images - I sold several of the B&W age-doorway image.
If you’re looking for a simple and straightforward tool to tweak or experiment with colors in photos without a steep learning curve, you might want to check out basic online editors or tools meant for beginners. I remember I once tried GIMP for something similar, but like you, I found it a bit overwhelming with too many features I didn’t need. I ended up using the built-in editor on my laptop, which was enough for quick adjustments like brightness, contrast, and color tweaks.
