Shoot HDR with TriggerHappy!
Ever wanted to shoot an amazing HDR image?
High dynamic range imaging (HDR) yields greater dynamic range between the lightest and darkest areas of photographs. Producing an HDR image requires taking multiple shots of the same scene. If your camera doesn’t have a built-in HDR mode, turning dials then pressing the shutter is the solution; however, changing settings manually can shake the camera blurring the photos and ruining the framing of the shot.
TriggerHappy does the grunt work for you!
Use TriggerHappy’s intuitive HDR mode to specify the number of shots, the EV interval, and the shutter speed. Shoot up to 9 shots and 16 stops of dynamic range. TriggerHappy lets you shoot HDR time lapses as well!
TriggerHappy brackets images for HDR by changing the shutter speed, and not aperture or ISO. You can choose to shoot with TriggerHappy’s Auto Exposure if your camera has built-in bracketing. With Auto Exposure TriggerHappy sends a request to the camera to take an image, but it does not specify a shutter speed.
For TriggerHappy’s Manual Exposure, put your camera in bulb and TriggerHappy will choose the shutter speed for each image based on the shutter speed you specify in the TriggerHappy App.
In the image above, a 9 second base shutter has been specified. Currently, we only let you choose the base shutter in whole seconds. TriggerHappy then computes the exposures of the other four shots based on the exposure interval specified. So for example, the '-8' shot would be 256 seconds. How did we compute that? 9 seconds * 8 EV which is equivalent to 9 * 2^8 which is 2304 seconds. Sounds crazy long, huh? But we decided to give you complete control!
Gotcha. We cannot guarantee correct shutter speeds under one second because camera makers’ interfaces don’t allow for accurate sub-second exposures. Usually with Canon DSLR’s anything faster than 1/20th second is inaccurate.
