7. Things To Consider With Live Photo
Live Photo is a brilliant way to quickly create fun clips for added interest and effect without any technical know-how or experience.
Live Photo is not a movie, it is an animation of multiple photos. Your Live Photo doesn't begin when you tap the shutter button, that actually is the mid-point of your Live Photo, the still that you capture is wrapped in 1.5 seconds of animation before and after.
When you open the iPhone Camera app with the Live Photos feature ON, it automatically begins taking pictures even if you don't tap the shutter button. It saves photos from before and after you take a photo and stitches all the photos together to make a smooth 3 seconds animation. The whole thing is a background process with the automated photos deleted if they're not needed.
The automated photos that make up the animation are of a lower resolution than the captured still frame. As an example, an iPhone X takes a regular shot at 4032 x 3024 pixels but when changing a key photo, that chosen image drops to 3662 x 2744 pixels. An image with an animated effect such as long exposure can be reduced to as low as 3281 x 2458 pixels.
Applying an effect or changing the key photo will crop the final image smaller towards the centre point. Try to leave some extra space around the edges of your shot if you intend to apply an effect later on. There will also be some softening to the animated image. This is especially noticeable in long exposure images. For the casual user these considerations may not be a limitation, for serious creatives though it can be a huge drawback to the photo’s potential when the image is viewed larger or printed.
Shooting with a tripod to ensure the capture is completely still may result in a higher resolution file, however the image will still be cropped and softened. Shooting with third-party apps is recommended if image quality is important.
