Easy to use and really useful in a remote location, allowing immediate feedback to the client and myself, giving endless possibilities for instant changes to perfect the final image. What have I done without it! Easily worth the purchase price.

Troubleshooting photography issues on the fly makes my job as a photographer extremely efficient. I highly recommend DLSR Assistant to any and all photographer who want to make an impression with their photography.

Colleen Curtis

Much simpler than EOS utility, with large preview which enables you to go back and forth between photos you just have made. Very intuitive and straightforward.
