With regards to picture stabilization there are two main stabilization varieties — digital and optical. However how come digital picture stabilization seems to be so good on my GoPro however not on my “actual” digicam?

There are plenty of causes for this, and this video from DPReview does a implausible job explaining it. It has to do with plenty of variables, like shutter pace, movement blur, and sensor dimension. I do not need to spoil your entire video however you might be questioning what the distinction between digital and optical stabilization is anyway? 

Mainly, Optical Picture Stabilization, or OIS, is when bodily elements of your digicam lens transfer independently of your digicam as a way to counteract small quantities of movement, whereas digital picture stabilization does this by way of software program: zooming the footage in and aligning particular person frames collectively as a way to attempt to recreate what OIS does in publish manufacturing although this is not with out its drawbacks which the video above does a greater job of explaining than I might. 

EIS might be performed both in digicam, the place it could actually work together with accelerometers, or it an be performed in publish, the place you might have a bit extra management. One factor that DPReview did not have an opportunity to the touch on on this quick video is IBIS, In Physique Picture Stabilization, which has similarities to OIS in that it bodily strikes one thing to counteract digicam shake however, not like OIS, is constructed into the digicam however makes use of the sensor as a substitute of lens components making primarily each lens you employ on that digicam stabilized.
