The tips below are written using a Canon DSLR, however, they are all perfectly valid for other makes and other camera types. The menu options may be in a different place, or the button may have a different icon so you may have to check your manual, but the overall principle is the same for every camera.
It is important to configure your camera with the base settings which work for you, so here are some of the basic camera settings which will help get the best possible shot.
Maximise Photo Quality
When it comes to file format, shoot in RAW rather than JPEG. The extra data that is collected in the uncompressed RAW format gives you more flexibility to adjust your shots post-shoot if necessary. Keep the ISO as low as possible to reduce unwanted noise, and set the white balance to auto. For the most part, auto white balance makes a good decision and as you get more confident you can change this yourself later on.
Master Exposure Settings
Reduce the amount of time you spend trying to rescue under and overexposed images in Photoshop by getting it right the first time, in camera.
Getting your head around exposure can be daunting, so let's start with the basics. When taking photographs, an image is recorded by light reaching your camera's sensor. You need a certain amount of light to expose the scene correctly; too little and the image will be too dark or underexposed. To much light and it will be too bright, or overexposed. The trick is getting this just right.
The amount of light reaching your sensor is controlled by three key components - aperture, shutter speed and ISO. These three form the exposure triangle.
The aperture controls how much light enters the lens, the wider the aperture the more light can enter. The shutter speed determines how long the camera sensor is exposed to the light and the ISO is how sensitive the sensor is to the light.
SLR's offer a range of exposure modes, from fully automatic, to fully manual. In between these two extremes are the semi-automatic modes, aperture priority and shutter priority which provide lots of control. Aperture priority allows you to set the aperture and the camera will work out the best shutter speed. Likewise, setting shutter priority mode allows you to set the shutter speed, and the camera will adjust the aperture accordingly. Which mode you need will depend on what you are photographing.
Aperture and shutter speed affect not just the amount of light you let into the lens, but also the way the images look. The aperture is used to determine the depth of field, which is the amount of the scene which is in focus. If you want a blurred background, you need a wide aperture such as f/2.8 and if you want everything in focus, from front to back, you need a small aperture such as f/22. The shutter speed controls whether a moving subject is frozen or blurred; the slower the shutter the more motion is captured.
Set the right combination of aperture and shutter speed and you'll notice an immediate difference in your photography.
The aperture is simply the hole in the front of the lens through which light enters. It is a diaphragm which can be made larger or smaller to control how much light reaches the sensor. The aperture size is measured in f-stops and is fractions, with f/4 being twice as large and f/8 which is twice as large as f/16. Lens apertures are typically in the range of f/4 to f/22. Each f-stop halves the amount of light reaching the sensor, and this can be compensated by doubling the exposure time.
The depth of field is a measure of how much of the photo is in focus, both in front, and behind, point you've focused on. Wide apertures of f/2.8 will produce an image with very shallow depth of field, which is great for macro and portraits, while narrow apertures, like f/22, will maximise depth of field and is ideal for landscape photography.
Shutter Speed Explained
You can control the way that movement is captured in your photos by getting to grips with your cameras full range of shutter speeds. Like the aperture setting, the shutter speed you choose isn't simply a way of controlling the overall exposure. It also has a visible effect to your shots enabling you to control the appearance of a moving subject.
Fast shutter speeds freeze movement, ensuring pin-sharp pictures no matter how unsteady your grip on the camera or how fast your subject is moving. Slow shutter speeds tend to blue movement, and so can be used for creative effects.
Shutter speeds are measured in seconds, or fractions of seconds. 1/10 is one-tenth of a second, 1/250 is one two-hundred and fiftieth of a second.
If you're shooting handheld you'll need a fast enough shutter speed to ensure that camera shake doesn't cause blurred shots. As a general rule, you need to use a shutter speed greater than the focal length, so for example, if you are shooting with a 200mm lens, your shutter speed should be 1/250 sec or faster.
Reduce Noise with ISO
ISO is a computed amplification of a digital signal. As with its film counterpart, digital ISO increases the sensitivity to light, at the expense of quality. High ISO film suffers from graininess, while digital ISO suffers from noise during the amplification process. For this reason, you should always strive to use the lowest possible ISO value. If you there is not enough light and your pictures are blurry because the shutter speed isn't fast enough, and you're already using the widest possible aperture the only thing left to do is to increase the ISO.
Target ISO values for outdoors will range from ISO 100-400 and indoors ISO 400-3200. Please note that these values will vary slightly depending on the ambient light in the situation and your camera. Digital camera sensors are improving all the time, but as a guide, anything above ISO 1600 will show noticeable noise.
Choose the Right Metering Mode
To determine the aperture and shutter speed required to expose a shot correctly at a given ISO, your camera measures the amount of light reflected back from a scene using a built-in light meter. The problem is that the camera does not know what you are photographing, so it assumes that the scene contains a full range of tones and tries to expose accordingly. There are however certain lighting conditions which confuse the camera.
A built in light meter will try to produce an even exposure made up of average midtones. A dark scene that's been exposed so it's dominated by midtones will look overexposed.
Scenes containing a relatively even mix of shadows, midtones and highlights won't give your cameras metering system much trouble.
As with dark scenes, because the built in light meter will try to render any scene as an average midtone, very bright subjects like snow will end up looking grey rather than pure white.
Metering options depend on the camera, but generally, there is evaluative, centre-weighted and spot. Evaluative metering takes a reading from the entire scene and uses an average to work out the exposure. Centre-weighted looks the central 60% of the frame to take the average, while spot metering takes a single reading from the selected autofocus point. Evaluative metering is useful when photographing landscapes when you need the entire scene well exposed. Centre-weighted is useful for portrait photography when the background isn't as important as the subject.
I usually stay with evaluative metering. I usually either set the exposure myself (using M-mode) or let the camera decide on the ISO, and in the rare occasion that the metering is off, I simply dial in some compensation.
Focus and drive settings are often overlooked, but they are essential for coping with challenging situations.
Take control of AF Points
When you look through your viewfinder and half-press the shutter you will see multiple autofocus points flash when they have achieved focus and you may hear a beep. These are cues designed to help you take pin-sharp photos. However, if you shoot using basic modes (auto, portrait, sports, landscape etc) the camera will select the autofocus points automatically based on what it thinks you are taking a photo of. This is usually what is closest, but this may not always be the case.
You can manually set the focus points, either to a region or specific point. This means when shooting portraits for example that you can focus on one of your subject's eyes, even if it's off centre in the frame.
In general, single point AF is best used when shooting stationary subjects. It allows you to fine-tune the autofocus point manually. The centre AF point is always the most accurate. Dynamic-area AF is great for shooting fast-moving subjects. Some camera allows you to select a group of AF points to help provide a compromise between the speed of a single point and the flexibility of dynamic area.
Go for a Drive
To ensure you capture the shot at the precise time, SLR's offer a number of drive modes. The two main settings are single shot, for stationary subjects, and servo drive for moving subjects. Some also offer a hybrid "AI Servo" mode which is a compromise between the two.
The cameras Drive Mode allows you to select whether a single image is taken when you press the shutter or a burst of photos. You can also use the timer to control the delay between pressing the shutter and taking the picture.
You should select the drive mode applicable to what you are shooting. If you are using the single shot mode for a moving subject then chances are by the time the lens has focused and you've pressed the button the subject has moved out of focus. Similarly using servo focus on a stationary subject may cause focus issues as the servo is constantly running trying to lock focus.
One of the main benefits of having an SLR is the ability to change lenses and most of us start with kit lenses, cheap everyday lens bundled with the camera to get you started. The key here is that they get you started. There will come a time when you want to add to your creative equipment, and expanding your collection of lenses is a great place to start. Here are the main points to consider when choosing a lens.
The size of your SLR sensor affects the angle of view of your lens. The smaller the sensor the longer the effective focal length. A full frame sensor has the same physical dimensions as a frame of 25mm film. Smaller APS-C sensors, used in the majority of mid-range SLR's, capture a smaller proportion of the image projected by the lens. This has the effect of increasing the focal length by a factor of 1.5x or 1.6x depending on the manufacturer.
We're not talking focus speed here, but rather the light gathering ability of the lens. Fast lenses have a wide maximum aperture, such as f/1.4. They let in more light which allows you to use faster shutter speeds. The downside is that they are often heavier and more expensive.
Another factor is that determines the cost of a zoom lens is whether it maintains the same maximum aperture throughout the zoom range or if the aperture gets smaller as you zoom in.
Lens speed is given as a range, typically written as f3.5-5.6 which means that at the widest zoom the widest aperture is f/3.5 and at the maximum zoom the widest aperture is f/5.6.
Some lenses have image stabilisation (IS) features in which servo motors create a gyroscopic effect to counter camera shake when using the camera handheld. This allows you to use a longer shutter speed without introducing motion blur caused by camera shake. Image stabilisation usually gives you a 3-4 stop improvement. A four-step improvement means that shooting with a shutter speed of 1/15th of a second with image stabilisation gives the same image sharpness as shooting at 1/250th of a second without image stabilisation.
Some image stabilisation lenses can operate in two or three modes. You should select the mode which best suits your subject, else the stabilisation will be ineffective or make things worse.
- Mode 1 - Corrects vibrations in all directions. It is mainly effective for shooting still subjects.
- Mode 2 - Corrects vertical OR horizontal camera shake during panning depending on the orientation of the camera.
- Mode 3 - Same as Mode 2, but only stabilises during an exposure. The other two modes are constantly stabilised. Panning with stabilisation on can be tricky.
If you are using a tripod, image stabilisation should be turned off as the servos will generate vibration which is not countered by the movement of the camera.
Select the Right Camera Memory Card
There are hundreds of different memory cards on the market, all with a multitude of features to consider. The main memory card formats are SD Card, CompactFlash, MMC, M2 and many more. Each type has a number of specifications you need to consider when buying a new memory card. Price and capacity are the features most people look at first, but not all memory cards are created equal.
I will be looking at SD Cards here as they are the most common today. Similar features and terminology apply to the other types. If in doubt consult your camera manual for the type and specification to use.
The obvious property to start with is capacity. You should NOT select the highest capacity you can find. Instead, look to one that provides enough for what you are likely to shoot and provide some capacity for spare. It's better to invest in 3-4 smaller cards than one large card. That way if a card gets corrupt, damaged, lost or stolen, you won't lose all your photos.
The number of photos you can get on the card depends on the format you are shooting in and the number of megapixels your camera has. JPEG files are smaller than RAW, and the more megapixels the larger the file. On my Canon 80d a JPEG is around 6MB while a RAW file is around 24MB. RAW files contain a lot more data and detail in the image and they are not compressed which is why the file size is so much lager, and why you should be shooting in RAW.
Take a few photos with your camera and look to see how large they are. Now multiply that value by the number of photos you expect to take and that should give you a guide for the card capacity.
The specification, or speed rating, of the card, is the next most important factor to consider. If you simply shoot JPEG casually then you can get away with a lower speed rating, however, if you shoot RAW and use burst mode, or take video then you need a high-performance card otherwise you will soon fill the camera buffer and your video will judder or burst mode will stop.
Speed ratings are usually given in terms of their write speed, measured in megabytes per second (MBps).
Speed class on SD cards features a C symbol with a number inside. This number represents the speed in megabytes per second, so C10 is 10 MBps. Faster SDXC cards get the UHS rating, which is a 1 (10 MBps) or a 3 (30 MBps) inside a U-shaped logo. For video-specific recording, look for a V icon and associated number that indicates the transfer rate. A V30 (30 MBps) card can handle HD video. For 4K video, look for a V60 (60 MBps) card.
Correct flash usage can make or break a photo. Flash is a great way to add drama to your images and really add a pop to them. It can fill in harsh shadows, illuminate your subject or make them stand out.
In automatic modes, the built-in flash will automatically popup and trigger when the camera thinks it is needed. This isn't always the best. I've had my camera on auto, outdoors in the sun photographing a landscape and the camera decides that the flash is needed. Other times when I want the flash the camera thinks I don't. If you shoot in automatic mode and the flash keeps popping up when it's not needed, there is usually an automatic mode without flash. Sometimes this is indicated by a flash crossed out. If the flash doesn't pop up then you can usually press a button to manually release it. The flash should then fire when you take a photo.
Always use red-eye reduction when photographing people or animals with the flash.
When using a hot shoe flash it's best to shoot in manual. By bouncing the flash you will get the best results in the shortest amount of time. This is where you bounce your flash off of a large surface such as the ceiling or a large wall. White walls work best as darker walls will tend to swallow your flash power and also has the potential to create a colour cast on your image.
The settings below should be used as a rough starting point, although you may need to adjust them slightly according to your scene.
- Aperture - Set this to around f8
- Shutter Speed - Set to 1/200. On most cameras this is the fastest you can go with flash.
- ISO - Use the lowest ISO to reduce noise as much as possible. ISO 100-200 is ideal.
- Flash power - Set the flash power to 1/16. You should refer to your flash manual for the procedure on this.
Take a test shot and you can easily adjust the exposure based on the results from that first image.
Always have spare batteries, and spares for your spares. Flash drains batteries FAST. Start with a lower flash power to start with, increase if necessary. This will increase battery life and flash recycle time (the time the flash takes to recharge before it will fire again).
Custom Shooting Modes
A Custom mode is a camera setting that allows the photographer to instantly recall a saved camera setup configuration by simply turning the top dial. These are typically C1, C2 and C3.
Configuring a "C" mode is very easy. Adjust all of your camera settings as desired for the "C" mode being programmed and then find and select the "Custom shooting mode" menu option located in the "Tools" tab. Next, select "Register settings". If more than one "C" mode is available on your camera, the mode number desired must then be selected.
Each time you switch to the C mode on the dial these settings will be restored.
Using C modes is very handy if you regularly switch between two different subjects, such as landscapes and action. Using these modes I can switch very quickly from shooting landscape to shooting an interesting bird or wildlife that I may spot and only have a split second to snap.
These settings can be changed after selecting them, for example, selection of C1 then adjust the shutter speed and ISO. I can switch to C2 then back to C1 and the original C1 settings are restored. If I want to make the new settings permanent then it's just a case of registering the setting again.
Below is how I configure my two C modes for two different situations.
C Mode 1 Sports/Action
For action shots, I prefer to use fast shutter speed. I set the camera to shutter priority, set the initial speed of 1/800 seconds, ISO set to auto and a wide-open aperture. I have enabled AI Servo autofocus with a large zone AF. I have high-speed burst mode enabled.
C Mode 2 Landscape
For landscape, I set the camera to aperture priority, set the initial aperture to f/11, auto shutter speed and auto ISO. I have single point centre AF and single shot autofocus, single shot drive.
