Checking Image Sharpness - Don't Be Fooled By The Small Screen
What may look pin sharp on your DSLR screen may in fact be blurred or out of focus. On first inspection the image of this FlyBe airliner may look sharp to the unaided eye, but when you magnify it you may see a distinct difference.
When out shooting it's well worth examining your images on your DSLR screen at regular intervals just to make sure your images are sharp and in focus - if that's the look you're going for! Make sure that you use the cameras facility to magnify the screen preview image and if possible exclude any extraneous light using a screen shade or in my case a Hoodman Hoodloupe 3. On the back of your camera will be a Magnify (Canon) or Zoom In (Nikon) button. Use the controls to check the whole image for sharpness at high magnification. If an image is not sharp, you can always reshoot to avoid disappointment on you return home.
Needless to say, I recommend that you ALWAYS shoot multiple frames.
Have a good weekend.
