I want to have imagery, which I indisputably own the copyrights to, that evokes a sense of cybersecurity, my profession and passion. This will be used on my LinkedIn profile immediately, but may find use in a variety of roles from desktop background to eventual re-use in a(nother) entrepreneurial endeavor.
Please see the attached for some samples of what I see others using for the same purpose.
Some sizes we need to accommodate:
1400 x 425 (LinkedIn Banner)
646 x 220
800 x 800 (Square, dimensions arbitrary)
1920 x 1080 (why not desktop background too?)
I am also curious how much additional cost would be incurred by producing a 4K version.
