Returned the photo for technical reasons

Hi, I do so love water splash photos but as the guy who knows, Abambo said  - this is not a sharp photo.

He mentioned the details so you will have help with any future shots of splash you take. Do read the guidelines for Adobe stock contributors and learn what not to submit and how to submit it when you have a perfect and photo to offer. Lots to learn and patience is needed. Best regards, JH

But that's not the reason for the refusal:
