I am trying to verify whether it is now common practice for cinematogrpahers to shoot everything in 4:3 aspect ratio and use matting in post production to achieve a widescreen. I am having a discussion with a gentleman who says the following and I want to know if it is true:
Shooting on 4:3 frames allows film makers to easily
convert their films to Widescreen and 4:3 formats
without losing anything and having both 4:3 and 16:9
frame lines in the camera view finder allows
composition to be adjusted so there are effective
images in both 4:3 and 16:9 formats at the same time -
Any help appreciated. Thank you.
