I just joined Dreamstime this past April. I've been uploading files since then, and I'm starting to get in the groove of uploading images. I only have 17 images up, so far, and no sales at all. I love the feeling you get when you see that another image has been accepted and is now online.
Taking pictures has proved to be actually pretty fun, and it doesn't require an extensive amount of effort. I set up a water drop shoot and got some pretty nice pictures. This is one of the water drop pictures online right now.
I also use Adobe Illustrator and Adobe Photoshop.
This is an image created with Photoshop...
and an image created with Illustrator.
Please let me know if any of you guys have any suggestions.
