Today we had a guest speaker come in from out of college to talk to us about the industry and also about cameras. His name was Gabs and has his own production company where he makes short film, adverts and music videos.
He started by showing us some of his adverts and telling us how he got the job offer and how he went about filming and setting up the for the shot. Saying about how he would assign people to certain jobs for each different shot and also how he would get a brief from the company or organization which he would have to apply to. This is good because of the fact that he have already got practice of this from our projects we have been given from our teacher.
When he was talking about cameras there was a number of topics he covered, one of these were lens. Saying there are two different types of lens, prime and zooms lens. Zoom lens being able to zoom in and out while the prime being fixed at a certain position. The prime lens are each different with each being more zoomed in or less. The zoom covers all of these, however at a lesser quality and also being cheaper.
The next thing he talked about was the f stop. This affected the lighting of a shot. The scale of the f stop could from 1.4 to 22. 1.4 being really open and letting a lot of light in the shot while having it at 22 makes very narrow and having it at very dark and not letting a lot of light in. It also changes the depth of field of the shot. With the higher the number on the f stop makes it have a much longer depth of field while lower has a much shallower depth of field.
The shutter speed is another thing that we learned from the speaker. Saying that normally the shutter speed should be twice the number that your frame rate is at. For at 25 the shutter speed should be at 1/50. When the number getting bigger the shutter speed gets slower. This is due to the fact that the shutter speed is time for the shutter to closes every second. For example 1/50 means it closes 50 times in one sec.
The iso is also numbered based, meaning higher the number the more light the camera has in the shot, this also means the picture is more gainer. When you have the number lower you have the shot being less exposed to the light and while also getting a much better picture quality.
