What do the metering modes mean?

The metering modes on your camera are as follows. Evaluative Metering This is a metering mode for use in most situations.  Even works with backlit subjects. The camera will automatically set the exposure so that it suits the scene. Partial Metering This mode is most effective to use when the background of the subject is much brighter.  Partial metering usually is in a small area in the center of the frame. Spot Metering This is used to find the exposure of specific areas in your scene.  Just point the middle focus point at the area you want to find the exposure for.  Landscape photographers really like this mode as it helps you figure out how to even out the exposures. Center Weighted average Metering The metering is weighted at the center and is averaged across the entire scene. I would recommend playing around with these settings to see which you prefer and in which situations you prefer them. Depending on what you are shooting you will find that some of these work for you but others

What do the letters on my camera's dial mean?

There are many different shooting modes on many different cameras.  On a SLR or DSLR camera you will see these modes. • A + = Auto • P = Program • Tv = Shutter Priority • Av = Aperture Priority • M = Manual • B = Bulb Here’s what they mean. Auto mode is when the camera makes all the decisions for you.  It will pick the ISO, Aperture and Shutter Speed depending on your metering mode and what the camera thinks are the optimal settings for the scene you are shooting. Program mode is when the camera will choose the optimal shutter speed and aperture depending on your metering mode. Shutter Priority mode is when the camera will choose the optimal aperture depending on the shutter speed you have selected. Aperture Priority mode is when the camera will choose the optimal shutter speed depending on the aperture you have selected. Manual   mode is when you make the decisions on all the settings. ISO, Aperture and Shutter speed. Bulb is for when you want to leave the shutter op

Understanding ISO

ISO was explained to me when I first started as how reactive to light your capturing surface is.  The lower the number the less reactive to light it is.  The higher the number the more reactive it is. This isn't exactly true when talking about digital camera's. In a digital camera think of ISO more like a gain control for light. What you are effectively doing when changing your ISO is turning up, or turning down the gain on your sensor.  Just like a radio if you turn the volume right up you'll get distortion. The same goes for ISO, turn it right up and you get noise. So, if you are shooting in bright daylight, there is no need to have a capturing surface that is super sensitive to light. So, in general you’d go for the lowest ISO you can use while still maintaining the shutter speed and aperture that you want to use. At night or in a dimly lit location, you’d want to use a higher ISO to be able to capture more light and use the shutter speeds you are after. Higher ISO can i

Aperture

Aperture is described by photographers in the form of f/x.x If your lens has numbers on it like 1:4.5-5.6 then that means it has maximum aperture of 4.5 at it's widest focal length and a maximum aperture of 5.6 at it longest focal length. Aperture is the size of the opening of the inside of the lens that allows light through to the sensor in your camera.  The lower the number, the larger the opening.  The higher the number, the smaller the opening. Aperture controls the depth of field that you have in your photos. The lower the aperture (say f/1.8) the less depth of field your photo will have.  If you put three items on a table all staggered in distance, then set your lens on it’s maximum aperture (lowest number it can do) and take a photo (as close to the subject as your lens will allow), you will see that only the item you focused on is in sharp focus and everything else will blur out. The more stopped down your aperture is (think f/16) the more depth of field your photo will hav

Shutter Speed

Shutter speed is the length of time you are leaving the shutter open on your camera.  It can make your photos lighter (if you leave it open longer) or darker (if you set it a little faster). Leaving the shutter open longer can have the effect of blowing out the highlights of your image (making the whites too white for the camera to capture any detail).  If you close the shutter too quickly you can end up with images that are under exposed (making the blacks too dark for the camera to capture any detail). Understanding shutter speed is a very important step in photography.  If you are trying to shoot sports and you notice that most of your subjects end up out of focus, then the shutter speed you are using is probably too slow.  You will have to find a way to speed up your shutter.  Either turning the ISO up or by opening the aperture by a stop or two will sort this out. This photo was taken with a shutter speed of 1/500th of a second. If you’re shooting a waterfall and you want that sof

The Basics. Shutter Speed, Aperture and ISO

Photography is a great way to get motivated to get outside and explore the world around you. It's one of the most rewarding hobbies and, at times, the most frustrating. To me, there is nothing quite like it. When I first started I'd jump in the car and just drive aimlessly for hours searching for interesting subjects and landscapes. I really didn't have much of an idea of what I was doing but I was loving it. There was no planning or even location scouting. At that point I think I was maybe succeeding in getting one or two shots that I considered "keepers" from these little outings. I soon found myself getting frustrated at the results I was achieving and had no idea how to improve my situation. What followed was the endless searching on the internet trying to find the "magic" settings that all the good photographers were using. It was only when I stopped searching for these "magic settings" and started looking at what these three things meant

What is this blog about?

 If you know nothing or very little about photography but you want to learn, this blog is for you. My name is Gavin and I started my journey in photography back in 2000 after buying a small 2 Megapixel Canon digital camera. From then on, I was hooked. I read everything I could in magazines and online, watched many hours of YouTube tutorials and gear reviews hoping to expand my knowledge. I know I'm not the worlds best photographer but with this blog I hope to share all the information that I have learnt and found helpful in furthering my knowledge and technique (both in camera and software). This is the main gear that I currently have in my bag (including what bag I'm using) Tenba 32L Axis Backpack Canon EOS 5D Mark III Canon EF 17-40mm f/4.0 L Canon EF 24-70mm f/2.8 L Canon EF 70-200mm f/2.8 L IS Canon EF 100-400mm f/4.5-5.6 L IS Nisi Pro Nano C-PL (Circular Polarizer) DJI Osmo Mobile 3 Sirui A-1205 tripod Canon 580EX II Speedlite Canon 580EX Speedlite I hope you find some of
