Since joining Dreamstime, I've submitted photographs taken with various cameras, starting with a good old point and shoot, followed by a bridge camera and now, with a recently bought DSLR. It's a natural progression but I feel it's still, more about the subject of your photo that counts, rather than the type of camera you use. I've only used the DSLR a little but comparing the three photos, can you tell, which image was taken with which camera (without looking at the date taken of course)
I'm sorry but I don't agree with you. We can see from the first second which Image is having a better quality and the others... I didn't look at the dates but I'm pretty sure the bridge is with the DSLR. It's not only about subject... I do agree this is very important but like Unteroffizier is saying, you need high quality on Stock where the review is precise on high quality. I would suggest you to experiment more light/shadow effect and computer work with photoshop or lightroom to increase contrast and lighting, to make it look more intense. Good luck :)
You may not notice much but enthusiast and higher end model DSLR gives you better noise control at higher ISO level. With a good lens image quality will be superior over the regular digital cams and smartphones. I feel DSLR is the minimum if you want to do stock when images are reviewed at highest resolution full size.
