Ratings and Reviews

Truly helpful! I recommend to any amateur photographers!

I just bought a Canon EOS 600D (Rebel T3i with 18-55mm kit lens) a few weeks ago. I'm new to DSLR photography and wanted to finally venture away from the automatic modes (automatic modes are not so great like point and shoots because they don't correct problems with internal software and photos are easily grainy). This app definitely helped me grasp the manual settings quickly! If you are an amateur photographer or thinking about moving away from point and shoot but you aren't sure you can do it... Buy this app before you buy your DSLR! You will know if you can handle it and you will also be able to grasp the controls more quickly after you bought it. Even if this app was $20, I'd still buy it! The only thing I would recommend to the developer is to include flash settings and maybe some different subjects to take a photos of. Everything else is A+++!

Great app!


I love this app. This is my 35 year as an art teacher and my first year as a photo teacher. This app provides me and my students an opportunity to get experience using aperture, shutter speed priority or manual with a total understanding of all the variables such as lens length, iso, lighting conditions etc. and then gives immediate results with a photo that lets you know see and understand if the photo was successful and why. The results also lists the selected aperture or shutter speed you used and what you need to do to make a successful photo. If you are using film, this will save you tons of time and money. This app is awesome!

Very cool!


This really highlights the relationship between shutter speed, aperture and ISO - thanks for demystifying it! It'd be better with a few more choices in subject matter (each with a different default light level), a way to frame the picture and a way to use the various types of light meters available on many SLRs. Perhaps some sample images could be made available that offer different areas for potential focus, with some foreground and background layers that could come in and out of focus depending on f-stop. Then perhaps different types of lenses, too... Nothing too out-of-the-ordinary, just the ones an amateur is more likely to want (standard kit and telephoto.)
