iStock (IS) portfolio serves as a reference. I have a steady growth of this portfolio with the acceptance rate between 65 and 70%. With the 100% acceptance I would have more than 450 pictures on line. I am producing and submitting pictures to all agencies more or less in accordance to iStock upload limit: 15 pictures per week. I was really looking forward to the increased limit of 20 pictures/week after reaching the bronze canister level (250 downloads), but they "temporarily" down sized that higher limit back to 15.

I started to submit pictures to Shutterstock (SS) and and StockXpert (SXP) much later than to other agencies. I needed 4 attempts to get accepted by SS and 5 attempts to get into SXP.

My acceptance rate in Big Stock Photo (BSP), 123RF and, also, in SS and SXP after the initial applications is much higher than in iStock.

Dreamstime (DT) and Fotolia (FT) behave quite differently. Initially, it was easy for me to get my pictures accepted there. However, the number of rejections is growing in these two agencies. It is, especially, true for Fotolia specializing in "type of photograph" rejections and a very inconsistent reviewing process. As the result, my FT portfolio is the smallest one among 7 agencies.

Anyway, the above plot represents a lot of learning, a lot of hard work, and some experimentation, e.g., with Polaroid image transfers, scanner art, and HDR images.
