Hey, everyone. So now that we've talked about the different camera types and what's going 2 2
on inside the camera, the shutter and the sensor, I want to talk about what happens 3 3
next and file formats, how is that picture actually saved. And there’s a couple factors 4 4
that come into which file format you would choose to save to. One of them is RAW, and 5 5
this is introducing some fairly complex things because RAW is uncompressed. And really when 6 6
you think of file formats you need to think about compression, because this is going to 7 7
be how is the computer inside your camera changing the image that you're taking. Because 8 8
a RAW image is uncompressed, all of the data that that sensor’s able to save is being 9 9
saved in a very big file. And typically the reason that you would choose RAW is that you 10 10
want to do some color correcting or maybe you want to zoom in a little bit on the image 11 11
you’ve taken. You’ll have a lot more information when using RAW. And on the flip side you have 12 12
something like JPEG and this is more compressed, you'll be able to take a lot more photos because 13 13
it doesn't take up as much space on your memory card. But you also lose some information — your 14 14
shadows and your highlights — you’re going to have just less space to work with. I just 15 15
want to introduce you to RAW vs JPEG, compression and how that affects your images. When talking 16 16
about file formats, typically you're talking about RAW, you’re talking about JPEG. The 17 17
main difference is being that RAW takes up more space, JPEG takes up less space. So when 18 18
traveling maybe you want a take more JPEG images, but ultimately if you want to be doing 19 19
some of that tweaking in post you'll need that RAW image just because there's so much 20 20
more data there. Alright everyone, so that's it for me on this 21 21
section. I hope it is useful for you and just know that there's a lot of information when 22 22
it comes to photography whether it's how the camera works, how it is saving the files and 23 23
what you do with the files. So we'll be covering a lot of stuff in future sections. We are 24 24
just getting started. So don't be overwhelmed if all this seems like a little much to you 25 25
because we will be going over it in more depth and detail later on. So for now thank you 26 26
very much and here’s Phil.
