I don't think you went too far with this one, Diana. I know exactly what you mean - because I used to belong to the ones complaining all the time myself.
As always, changes are hard to accept and scary, especially if your main job/earnings are concerned. For many of us who got *early* into this business, SS was an easy way to earn pretty well and make a living - and I mean REALLY EASY. We started focussing on SS (or several agencies) and almost forgot about everything else surrounding us and our small stock world for a while - simply because we could afford to. I think it's time to let go now, though. I don't mean necessarily quitting SS or the stock business altogether, but noticing again how much larger the world of photography or design actually is. In an older thread you once wrote that we shouldn't see ourselves as "stock contributors", but rather as graphic designers (or photographers) instead and should try to do the best job we're capable of as such. IMO this hits the nail on its head.
On the other hand, I think adapting to the market as it is now is much easier for us graphic design people than it is for a photographer, simply because our way of working differs significantly from theirs. We're basically "visual problem solvers" and used to constantly checking out new techniques. Not talking about professionalism or "better" skills here at all - all of the excellent photographers in here actually have my deepest respect! - but perhaps a "broader spectrum" we can make use of if it comes to creating a complete product, which doesn't solely consist of one photo or illustration. Learning completely new things already *is* part of our daily job, while a photographer may have to actively *decide* e.g. to venture out and try their hands on layouting or creating complex smart objects in order to complete their photography and transform it into something new.
It's worth trying, though! I also know some super successful photogs who did exactly that. Some of you may e.g. remember Sandra Cunningham? In the early days she used to be something like a Shutterstock star - she did excellent composites and stills. Then she started specializing in book covers and macro stock. Looking at her cover photos you can feel that she literally breathes graphic/cover design, although she doesn't even have to do that part herself. Or all those photographers who started doing social media templates. Styled stock, of course ... However, things certainly don't get easier, but I honestly believe there are still niches to be found and things to be created, which someone actually needs.
