Coming with another update to the gallery of free images for editorial use on the Steem blockchain. See the link.
Those conditions apply only to what was specified. Please, learn more about the project.
And since people are still asking, mentioning me like in "image by @manoldonchev" is fine.
Including a link to the source like this: words in  followed by a link in (), no intervals/spaces between the two types of brackets, that would make you feel safer in regards to other blockchain entities.
My latest contribution:
Ten new images uploaded. Mountains.
If you like what I'm doing and you wish to support the initiative, consider backing me. That will improve both quantity and quality. And the frequency of the uploads, of course.
Also, there are files for print and/or for commercial use as rewards. For personal use like desktops or wall decoration, too.
Some more basic tutorials also coming,
after the first one about Exposure,
and the second one about Depth of Field.
Other recent tutorials:
Enjoy the rest of the gallery which now contains more than 440 images.
Please, visit the gallery linked above for more!
Have mountains of inspiration!
