Website for photographer, portfolio
I totally agree with Jack! I really like Templatemonster themes but I think that they look too commercial. I take photos from Unsplash add some photo effects and get an awesome unique template. I recommend you to use this method for your photo blog cause it will look more individually.
Yes, of course! I think you need to find some good theme with user-submitted photo gallery that can quickly adapt to any type of browser and device. Theme must be responsive also. Look for this professional content sharing WP themes https://www.templatemonster.com/blog/best-content-sharing-wordpress-themes-2017/ from Templatemonster. I think it is will be the best decision.
