Introduction to the Exposure Triangle
In understanding ISO, Aperture and Shutter Speed it’s important to note that all three are present in every photo you capture with your camera. The degree in which they are applied will depend on various camera and / or lens settings and lighting conditions.

Long Exposure Photography Setup & Tips
Long-duration shutter speeds / long exposures are applied when shooting after sunset, night photography and / or fireworks. The photographer will use longer shutter speeds to capture a low / fading / after-sunset or a night composition - all of which could provide for some really dramatic exposure effect. Long exposures (during daylight) are also achievable with the use of filters (see section on ND filters). Read more>>


Free Canon Shooting Simulation: Exposure practice for your DSLR Camera
The Canon simulation software provides a practical and intuitive way to learn and apply the Exposure Triangle, different shooting modes (Manual / Shutter Priority / Aperture Priority) and to practice shots by changing the settings (and seeing the inter-relationship of ISO / Aperture / Shutter Speed). Visit the Canon website to practice your shots Read more>>


Ultra Wide-Angle Lenses: APS-C vs Full Frame Focal Lengths
Ultra Wide-Angle Lenses: different focal lengths (comparing Crop and Full Frame focal lengths). On my website I have made two posts from the same Woodbridge Island, Cape Town location for interested photographers looking at wide-angle lenses. Read More>>

Birds in Flight Photography: Cropping & Post-Processing
I recently responded to a request from one of my delegates from our latest Birds in Flight Photography Workshop Cape Town with regard to image cropping and the amount of post-processing required (as applied in my own Birds in Flight images in my regular shooting environment at Woodbridge Island, Cape Town).

Starting Out With Birds in Flight Photography
Many photographers, when they first getting interested in Birds in Flight / Action Photography, are of opinion that they require professional grade gear, or at least the latest and / or greatest DSLR / Lens combination that they can afford. Birds in Flight Photography gear acquisition can very quickly spiral out of control for new photographers putting gear first and not being mindful to all the basic requirements for getting started.

Aperture Demonstration for New Photographers
A brief aperture / background blur demonstration of 8 images captured at different apertures, but exactly the same depth of field between camera / subject and background distance) to show what effect an aperture change will have on background blur when changing the aperture setting on the camera. Read More>>


Focus Stacking in Macro and Close-Up Photography
In Macro and Close-Up photography we are challenged with a very narrow Depth of Field (DOF) in creating a sharp image (and providing for more and / or less out of focus areas). In order for extending the DOF across the image image or part of the subject(s) in the frame photographers use focus stacking for achieving a more desired / sharp result. Read More>>

Difference between Digital Noise and Background Blur
Blur can really mean different things in digital photography, but should not to be confused with unwanted graininess or digital noise across a digitally created image. Unwanted noise generally occurs when:shooting in low light, when a digital camera's ISO setting is too high. Read more>>


The Difference between Optical and Digital Zoom
Difference between Digital Noise and Background Blur
Canon EOS 700D
To bring far away subjects closer into the frame photographers have a choice to either use a telephoto zoom lens or to move closer to take the shot at a closer focal length. The latter is not always possible, and many photographers rely on a variety of zoom lens options for bringing a variety of subjects closer. Read More>>

Using the Canon RC-6 Remote for long exposure photography
The Canon RC-6 Wireless Remote Control is an inexpensive wireless transmitter for Canon EOS DSLR cameras and a really handy accessory for pairing with my Canon EOS 700D. This tiny remote release assists me mostly with long exposure landscape / seascape photography (on tripod) when using Av / Bulb mode for shutter releases of up to 30 to 40 seconds. Read more>>

What is Camera / Lens EXIF Data?
EXIF Data is the identification and listing of an information metadata tag and its values -available for DSLR / Compact / Smartphone cameras before and / or after taking the photo. Generally found on your LCD screen viewing image detail or when downloaded in Canon's Digital Photo Professional, Google Picasa / Adobe Lightroom (and other camera / editing software). Read more>>
