Tested on: Nikon 3400 DSL (entry-level digital SLR) compatible and suitable My level of photography: Amateur and educational personal use, I'm a bit disappointed. I feel like this panel attached to your camera in daylight or normal light is not really needed. If my photos are too dark, what can this light do, my camera can, simply by adjusting the aperture settings in manual mode. The filters are good, but the time it takes to swap out one filter for another is something I could do in my photo editing post. I usually crop software, so why not just make the photo cooler or warmer in the same software application? The only use I have for this device is recording videos at night. This is something my camera can't do on its own without special equipment. That light at higher settings absolutely blinds people's faces, so you'll need to shoot at lower settings for close-ups of people at night. Overall the product looks well made and works as it should. Very easy to use and understand, it's a standalone device, you don't need to mess around with a camera to make it work. To get more out of this product I look forward to mounting it on a mini tripod (not included). I want to use it for photography in my studio so I can add a brighter light source if needed. I'm wondering if it can replace one of my stationary photo lights that take up quite a bit of space.
