Photo Basics

All right, so this section is Photo Basics, and I know that some of you are gonna know most of this stuff. That's fine, this is a review section for you if you want. This is for people who maybe are getting into a more serious camera for the first time. A little review, if you already know this stuff. Feel free to jump to the next section. The Nikon D-7500 is a digital single lens reflex camera. Single lens, we get one lens on the camera. Very high quality lens, of course. In the lens is an aperture system. This is one of a number of different ways of controlling the light that we are recording. This opens and closes to different sizes. We'll have different f/stops, depending on which lens we have on the camera, possibly ranging from f/1.4 to f/22. This is one of a number of ways that we have of controlling the amount of light coming in the camera. Beyond just controlling the amount of light, it controls how much is in focus, also known as our depth of field. We can have very shallow d...

epth of field, with the foreground and background out of focus, or we can stop down our aperture like this, and gain more and more depth of field with each aperture that we drop down in size, until we get to the smallest one, which will give us the greatest depth of field. There's a lot of artistic control that we have within the use of that aperture. Light comes into the mirror. That's the reflex portion in SLR. Light bounces up to the focusing screen and out through the viewfinder, and so you get to see the real world with your own eyes through this. When it's time to take a photo, the mirror needs to get up and out of the way, so that light can get back to the image sensor. It first needs to get past the shutter unit. The shutter unit has two parts, a first curtain and a second curtain. When it's time to take a photo, the first curtain will drop away, exposing the sensor to light right here. That's your exposure time. The second shutter will come in, close it off, and end the exposure. The mirror will return to its standard position, and you get to see what the camera is pointed at for the next shot. Just be aware that what you see through the viewfinder, you're not getting to see exactly when the picture was taken. We have lots of different shutter speeds. It's our second way of controlling how much light gets in the camera. We'll have shutter speeds ranging from an eighth-thousandth of a second, down to 30 seconds. They'll be used for topping motion or freezing motion under varying conditions. The sensor is one of the most important parts of any digital camera. The size of the sensor, the style of it, plays a great impact in the types of lenses you can use, the quality of the photos, and how the whole camera works. This camera uses a fairly large image sensor, not the largest of the common sizes. The most common size, for quite a while, was 35 milometer film. There is a lot of digital cameras that use that same size sensor, which is what we know as a full frame sensor, these days. This uses an APS-C sensor, which has a crop factor or 1.5, which means it's 1.5 times smaller than that full frame sensor. So, images seem to be a little bit on the magnified side. Nikon's compensated for that with coming out with special lenses that make everything look normal again. It's the size of sensor this has, kind of an intermediate size, which means that the camera can be a little bit smaller. Lenses can be a little bit smaller, maybe even more affordable, in some cases. All of this is just part of how cameras work and how photography works. If you would like to know more about that, as I say, you might wanna check out The Photography Starter Kit for Beginners, or the Fundamentals of Photography, depending on how in depth you want to get into the world of photography.

Great, great course. Could not be any clearer on what to know, what to do, and in all, making understanding my camera a fun thing! Well, well, worth that cost. A steal really!!


Helps you master the camera controls very quickly. I'm glad I took the course. Without it, I'm sure it would have taken me years to know and use the full power of this camera. Great Course. Highly recommend.

This is a great course! I recently bought a D7500 and was somewhat stymied by the large number of different possible settings and the several hundred page user manual and menu guide. This course covers the vast majority of what I need to know and in a reasonable amount of detail. I especially liked the material on menus as he went through most of them in detail. Additionally all the slides shown in the course are available in pdf as well as several pages detailing the authors recommended settings. I highly recommend, especially given the $24.00 special offering for this.
