Here is a quick list of most common problems with photo we receive. As many people actually take photo with the purpose of putting them on the canvas I think it may be useful read.
1. Blur - caused by the unsteady hand. Can we easily avoided - by using a tripod. If you haven't got a tripod think about something you can rest your camera against, like chair, wall or a table. Blur can be also reduced when the exposure time is decreased. Look for this option in your camera settings. Some people suggest to even hold your breath as you press the shutter button. Easy to try - and nothing to loose. Good practice s also to keep your camera in your both hands.
Similar problems may be caused by not focusing the camera on the subject. Make sure that you let your camera focus by pressing the button half way and waiting until it is ready before pressing it all the way down.
2. Under Exposure/Backlighting - the subject of the photo is too dark and is lacking the details. This happens a lot when photographed person is standing in front of the window, or when the sun is behind the person that you take photo of. The technical reason behind that is that the camera is measuring the amount of light in the scene and adjusts to the the brightest areas. There are no easy fixes for that, best is to avoid this if using an automatic camera. With some cameras you can change the exposure time and overexpose the photo which will help the subject.
3. Red eyes - although easily fixed, can be also avoided in many cases. It is caused by the flash light bounced off the eye retina. Try to avoid using flash - it is better to use natural sources of light if available. Always look for red eye reduction version of the flash in your camera. Ask the person that you photograph not to look directly into the camera.
4. Low resolution - with new cameras having more and more megapixels make sure to make the most of it. I personally always take photos with maximum quality settings my camera can give. Not only you will capture most details this way but also you can produce bigger canvas prints or other printouts later. Bigger files will take more space but I don't think this is an issue at this day and age when hard disk & camera memory cards grow at outstanding pace. Other reason for poor quality os also usage of digital zoom - this doesn't really do much more than cropping the photo for us, effectively magnifying existing pixels. Avoid using digital zoom at al costs. It is always better to get closer to your subject. Read our canvas resolution guide for more info.
5. Lack of focal point - avoid shooting a photo against busy background. When taking a photo think about what you'd like to see on you canvas prints - possibly make a test photo. Remember that to make a canvas prints with the image wrapped around the canvas frame we will need at least 2" of the photo extra around the subject. So plan your photo carefully. Sometimes we try to include too much in our photo, causing it be too clattered and less interesting. It may be better to take a few shots and combine them into a collage or a photo sequence.
6. Not reading your camera manual - this is the best initial source of information, which lists all of your camera options, which is neglected by many. New cameras have lots of extra features, manual settings which can greatly improve your photos. Good practice is also to take lots of them. Professional photographers take hundreds if not thousands of shots to choose a few that are exceptional.
Hope this helps,
Looking forward to receiving your great photos
