Weekone blog Introduction filmmaking
First week of lectures we looked at some interesting videos from filmakeriq.com the main things we covered in these videos were color temperature, and lenses.
Things I learnt were:
1. Color temperature is the temperature of light thought the electromagnetic spectrum.
2. White light is a mix of all colors e.g prisim.
3. Plaunks law... lots of maths i didnt understand
4.CDI color rendering index (I think) (daylight at noon being 100)
5. Index of refration air = 1.000293 water 1.33
6. focal length is the distance between the center of the lens and the focal point or sensor
7. field of veiw - focal length:sensor size
8. F stop = apature size/focal length
9. T stop = exposure compensation
10. Prime (fixed lenses) and Zoom lens
11. Varifocal and Parfocal. (ENG lens will not adjust focus when zoomed)???
I would like to go over understanding how to use the white balance of the camera in future and setting my own custom balance, understand focal length of lense more and the maths of the F-stop. and how to compensate for Parfocal lens (staying in focus while zooming).
Re: parfocal lenses -- ha, this is a very tricky skill that is probably near impossible! :-)
ReplyDeleteWe will partake in some practical exercises in the weeks ahead that will reinforce some of this theory.
If you have done any extracurricular research, feel free to post it on these blog posts (i.e. screengrabs, photos, diagrams or youtube links etc etc).
