Now, the equivalent of grain in film, is the noise in digital cameras. So, if you turn up the ISO to 3200, which is very high, it will take pictures at night, but it'll also increase the amount of noise you have. With intelligent ISO, it will change the ISO, which is impossible on a film camera, but it will change in a digital camera and give you more noise, but better exposure and shutter speed levels. Some other things that are important are in a prosumer model is that you have a large LCD screen that's got high resolution. So the LCD panel is what you're going to use quite a bit. And I've attached this accessory, which you could buy, that will block out the sunlight, because in direct sunlight, you won't be able to see the LCD panel. You'll have to view through the viewfinder, but sometimes that's inconvenient because you may want to view it from a distance and this will shade it. It's sort of an auto shade. This has a true joystick and then it has the button joystick here and this uses the lithium ion battery, which is basically proprietary to certain models of this particular company. This is the Panasonic and it uses a Leica lens. It uses SD, which is secure digital format, which is pretty much the universal, I mean, there's about twelve of them, but this is the most universal. More cameras use this than any others. And, this will use the high capacity ones so you could put a larger capacity one in here in order to take more pictures. When you're using the raw format, you're talking about thirteen megapixels to shoot a raw exposure, where it only takes two or three megapixels to shoot a JPEG. But, the raw exposure format has the ability to use a lot more different things as I've just mentioned in a previous one.
