No I will not post links; I don’t want to publicly chastise strangers. I often peruse various Audubon groups on Facebook and Instagram. Facebook Birders is one of the best. Top level highly professional work–from around the world–is routinely displayed there–much of it far better than the best of my own.
Many such groups are predominantly comprised of photographers who see themselves as (like me) amateurs. I was struck this morning by the number of well composed images with fancy watermarks and poor editing. There is one well-known wildlife photographer on Instagram, who routinely gets a thousand or more likes for each new post–whose compositions are outstanding. And whose image editing is poor at best.
There is so much really good free software available. Perhaps open source needs better advertising.
