One of my favorite things about Instagram is discovering an absolutely amazing photographer who also shares their skill for all on IG instead of just the professional photography sites. I mean, I really don't follow the pro sites anymore at all. Not even Flickr and I still, technically, use Flickr.
I've discovered some great ones such as Drew Gibson's disc golf photos (okay, admittedly, Drew is the subject and someone else unnamed is taking the photos, but whatevs), Shutterbug_Erica's macro and nature photography, Anthony Caere's primate photography (discovered via Dave2), and Kevin Goodrich's nature shots (in the spirit of full disclosure, I went to middle and high school with Kevin and it's cool to reconnect via photography).
But my current obsession is Euan Rannachan's shark photography.
Some are straight up shots while others have had filters added or been retouched for the sake of artistic vision. Whatever the case, they're amazing! Check out some of my more recent favorites (in order to drive some traffic to his site, these are Instagram embeds so you may need to click through from your RSS aggregator)...
Please go show him some well-deserved love.
