I think Bryan Peterson is pretty great, and has one of the best books on understanding exposure. He explains exposure – talks about Aperture, Shutter Speed, ISO, Light and special techniques and filters.
What I liked most about the books is the examples and the way he explains exposure. When you’re first trying to understand how your camera works, words like ISO and Aperture don’t mean a thing, but he explains it in a way that makes sense. For instance here is a quote when he explains ISo
“To better understand the effect of ISO on exposure, think of the ISO as a worker bee. If my camera is set for ISO 100, I have, in effect, 100 worker bees; and if your camera is set for ISO 200, you have 200 worker bees. The job of these worker bees is to gather the light that comes through the lens and make an image. If both of us set our lenses at the same aperture of f/5.6 meaning that the same volume of light will be coming through our lenses – who will record the image the quickest, you or me? You will since you have twice as many worker bees at ISO 200 than I do at ISO 100″
He also has an updated version to the one I own – Understanding Exposure the 3rd edition that you might want to check out!
Found this excellent explanation of what exposure is by Matthew Gore he does an amazing job explaining the difference between aperture, f-stop and ISO. Those are the three elements one needs to understand when taking a picture with your DSLR camera.
If this is the first time you’re hearing these words or you have been around your DSLR camera for awhile now, it’s a great video to watch. Even things I think I know about my camera I will watch a video or read and article and think “oh yeah, now I get it” It’s always good to go back and re-learn the things you think you already know. What you will find out is you actually don’t know it all… There is always something new to learn! This is why I love photography, there is always something to learn!
I love the way a book feels in my hand. I love curling up on the couch with a cup of tea or a beer depending on the day and the mood. I have accumulated quite a few photography books some not so good some amazing. The ones I pick up at the local library usually make me laugh with the ladies and their big blond hair with colorful leg warmers. But once you get past the 80’s vib the information is still the same. Light still enters our lens and after a certain time we use our shutter speed to take a picture mixed in the ISO and you have a recorded image.
I bought Understanding Exposure by Brayn Peterson 2 years ago. I read the book, but not all the way through. At that time I was trying to figure out the aperture on the triangle, but today I picked it up to read about metering. It is a great book with beautiful pictures. Bryan Peterson is excellent at conveying to the reader exactly how exposure works. He talks about aperture, shutter speed, light and special techniques and filters. Since I bought mine he has newer version of Understanding Exposure that you might want to check out! Would definitely recommend this book to anyone trying to understand exposure!
Last night was my first Photography Basics Class. It was a 2 hour class that passed me by in a blink of an eye. This class was absolutely amazing. I assumed since the class was called “Understanding the Basics” we would start off with what the dials mean on your camera etc. After everyone knew that we would move on to the exciting information, but I was wrong we dived right into Understanding Exposure!
But first we talked about the proper technique to hold your camera (which apparently I didn’t know)
How to hold your camera:
The position of your right hand should grip the right side of your camera – forefinger lightly above the shutter release. This part I was doing correct….
The position of your left hand should sit under the lens holding the weight of the lens. So you are cradling the lens in the palm of your hand. I was cradling the lens with the palm of my hand to the left of the lens.
Moving on with the class we talked about how the SLR (Single Lens Reflex) works, but I will have to write about that when I understand it a bit better myself. I thoroughly enjoyed talking about how the components to the camera work, how the shutter opens, how lights hits the sensor, what a sensor is. But I would have a hard time repeating what I learned so I will do a little homework on that subject first!
Understanding Exposure – The amount of light that hits the sensor or film.
Exposure is such a huge topic, but I learned a few things that were great in helping understand the mysteries to exposure. The key to controlling a photographic image is Understanding exposure.
Exposure is determined by two things
Exposure is controlled by two things:
Exposure in photography are measured in values called stops. Stop is a term you will hear again and again in photography only today did I actually understand its meaning (well almost understood it still pondering everything he said about it). A stop is defined as double or half the amount of light. You can describe a stop of light in two main ways, f-stops and shutter speeds
Understanding Shutter Speed
Understanding how F-Stop and Shutter Speed work together
