Learning about Exposure - The Exposure Triangle

Learning about Exposure - The Exposure Triangle
A Post By: Darren Rowse Bryan Peterson has written a book titled Understanding Exposure which is a highly recommended read if you’re wanting to venture out of the Auto mode on your digital camera and experiment with it’s manual settings. In it Bryan illustrates the three main elements that need to be considered when playing around with exposure by calling them ‘the exposure triangle’. Each of the three aspects of the triangle relate to light and how it enters and interacts with the camera. The three elements are: ISO – the measure of a digital camera sensor’s sensitivity to lightAperture – the size of the opening in the lens when a picture is takenShutter Speed – the amount of time that the shutter is open It is at the intersection of these three elements that an image’s exposure is worked out. Most importantly – a change in one of the elements will impact the others. 3 Metaphors for understanding the digital photography exposure triangle: The Window Aperture is the size of the window.

curiosity counts We live in an exciting and interesting time — one when some of our most commonly accepted ideas, traditions and principals are being challenged. This past week featured a fascinating read in the Wall Street Journal asking “Are Playgrounds Too Safe?”, making the case that “decades of dumbed-down playgrounds, fueled by fears of litigation, concerns about injury and worrywart helicopter parents, have led to cookie-cutter equipment that offers little thrill.” Recently Forbes featured an article smartly challenging things many of us grew up being taught and often adhere to still. 1. 2. 3. …More

One of the most effective ways of cutting through this haze and capturing a vibrant photo with saturated colours and a deep blue sky is to use a polarizing filter. The photo of the mountain range, above left, may have been taken under bright, sunny conditions, but the result looks hazy and is lacking impact. Checklist: Using polarizing filters 1: Buy a circular polarizing filter which matches the thread on your lens; check the end of the barrel to find out the correct size. 2: With the polarizer screwed onto the end of your lens, turn the outer section to see the polarizing effect. 3: To prevent your DSLR from counteracting the polarizing effect, set the White Balance to Daylight and consider applying negative Exposure Compensation of, say, -2/3 or -1 EV.

These tips are not by any means rules to follow. RAW vs JPEG The RAW vs JPEG topic seems like a never ending debate in photography. Some photographers say shoot RAW, while others say shoot JPEG. What is RAW format in digital photography? Sand Dunes - Shot in RAW I remember my first time going through the camera options and reading the Nikon D80 manual, wondering about what RAW does and why I should consider using it. Sounds familiar? 1) What is RAW? RAW images, also known as “digital negatives” are virtually unprocessed files coming directly from the camera sensor. 1.1) Advantages of RAW format Compared to 8-bit JPEG format that can only contain up to 256 shades of Red, Green and Blue colors (total of 16 million), 12-bit RAW images contain the most amount of information with 4,096 shades or Red, Green and Blue (equivalent of 68 billion colors!) 1.2) Disadvantages of RAW format 2) What is JPEG? JPEG is the most popular image format for photographs today, capable of displaying millions of colors in a highly compressed file. Take a look at this image:

13 Creative Exercises for Photographers Like the world’s tidal waters, photographic creativity ebbs and flows for many of us. Sometimes creativity can use a jump-start, an artificial method to get the photographer to start looking at the world in a new way in order to facilitate, restart, refine, or improve your photography. There are many ideas on how to get yourself to push through an artistic block or inspire you to further expand your boundaries. Not all of them involve the camera. Several websites and books publish a mix of assignments or exercises for the intrepid photographer. These are my versions of various exercises that have been passed down from one creative generation to another. Exercise 1: Two Dozen Pick a location. The first time I did this, I hit a virtual brick wall after about 12 shots, and that was eye-opening in many ways. Exercise 2: Ten of One Take 10 unique and/or abstract photographs of 1 small subject. The smaller the subject, the more challenging this can be. Exercise 3: Four Corners You get the idea.

Digital Camera Sensor Sizes: How it Influences Your Photography This article aims to address the question: how does your digital camera's sensor size influence different types of photography? Your choice of sensor size is analogous to choosing between 35 mm, medium format and large format film cameras — with a few notable differences unique to digital technology. Much confusion often arises on this topic because there are both so many different size options, and so many trade-offs relating to depth of field, image noise, diffraction, cost and size/weight. Background reading on this topic can be found in the tutorial on digital camera sensors. Sensor sizes currently have many possibilities, depending on their use, price point and desired portability. The relative size for many of these is shown below: Canon's 1Ds/5D and Nikon D3 series are the most common full frame sensors. Camera phones and other compact cameras use sensor sizes in the range of ~1/4" to 2/3". The crop factor is the sensor's diagonal size compared to a full-frame 35 mm sensor.
