![]() The GoPro Hero 4 offers a standard video mode and a Protune mode. Rule of thumb: the lower the ISO the better the image quality and vice versa, the higher you go with ISO the noisier the photo becomes. ‘Noise’ is a synonym for grainy pictures. Theoretically you would think that bumping up the ISO would do the trick, but the downside of high ISO’s is the digital image noise that is introduced at the same time. The higher the number the more sensitive is the image sensor with regard to detecting light. ISO defines the light sensitivity of the sensor. But the camera has the option to decide on a different ISO rate. Night-photo-mode(edited+2eV)–iso-limited-to-200–shutter-AUTO Video mode: How to remedy low light situations?Ībove explanation tells us that the camera can’t go slower because of the set FPS rate. night-photo-mode–iso-limited-to-200–shutter-AUTO night-photo-mode(edited+1eV)–iso-limited-to-200–shutter-AUTO Looks pretty realistic for the dark area I shot the photos. The actual night scene as I saw it was between the Original and the +1 eV version. More detailed Photoshop work could make the photo even better and smoother. The first image is the original photo out of the camera, the 2nd is post-edited with exposure +1ev, the 3rd post-edited with exposure +2ev. The GoPro phone app is the place where I check the overall situation before changing settings.įollowing a PHOTO NIGHT SHOT. Protune-ON, ISO limited to 200, and SHUTTER: auto. I would always try to go with the lowest ISO that still does the job. For well lit streets an ISO 1600 should be the better solution over the brighter but noisier ISO6400. Both settings couldn’t convince me, but again, the scenery was anyway very dark. The ISO 1600 video was overall way too dark but was noise-wise way better. The ISO 6400 video is OK lit but very, very noisy. I tested in video mode in a very dark scenery (only 1 street light 50ft away from me) first in Protune mode at setting ISO 1600 and compared that to Protune OFF which leads to an automatically chosen ISO 6400 because of the darkness. Shooting at night in 48 has no advantage over 24 or 30 unless you want to slow down your video later in editing mode. That means the shutter speed can’t be slower than 1/30 of a second.įrom your still photo experience you might know that 1/30 of a second is not slow enough to let enough light through the lens for night shots.Ĭonsequently, shooting video at 24 fps should be slightly better and shooting at 48 or 60 or higher should result in worse video shots. E.g., if you are shooting in 30 fps the camera will actually take 30 images (at the given resolution) per second. In Video mode the camera is bound to the frame rate you have set. In Photo mode or Night-Time-Lapse mode you can achieve really nice results because you (resp.the camera) have more flexibility regarding shutter speed. The following are general considerations.ĭifferentiation between Still Photos and Video Mode Photo- and video-wise. I can only speak for my Hero 4 Black Edition but I assume it would be the same for the Silver and Standard Edition. Here’s my take on the low-light capabilities of the GoPro Hero 4 in general. ![]()
