Note how in the HD movie stills the 4:3 image fills more of the frame, in
some situations this grey (or black) border may be acceptable depending
upon the context of the video. In most cases though it might
be better to
crop this image to fill the frame and lose this distraction.
Image Size, is also important to consider when we are setting up the
camera, as with aspect ratio, it will affect how the image is displayed, or
printed. For printing it is generally accepted that a pixel density of at least
300 pixels per inch is required to produce a good print from modern ink
jet printers.
For screen presentation this pixel density can be reduced to
70 pixels per inch. In printer language this pixel density is usually termed
DPI (or dots per inch) however it is the same as pixel density.
So when choosing the image size, in the menu of the recording set up
screen, you can elect to always shoot at the highest image quality
knowing that you can always “crop” into such an image to allow for fitting
to a print size which doesn't correspond to either a 4:3 or 3:2 aspect
ratio. If the images are for just inclusion on social media or web pages,
for example in a personal blog, then you can save upload time if you
choose a smaller image size. Similarly for stills which will be used in HD
video productions the 2M image size has enough pixels to
