Day 27 | Why are My Photos Blurry?
Blur can be avoided with some simples tips, so lets dive right in shall we?
1. Subject Motion Blur
How do I know if I have Subject Motion Blur?
Typical shutter speeds range between 1/60th of a second and 1/500th of a second. When taking photos of children your shutter speed should be set at 1/125th or higher to avoid blur.
Solution to Subject Motion Blur
There are three ways to correct subject motion blur
- Increase the ambient light by moving outside if you are indoors or turn on overhead lights.
- Increase your ISO
- Open your lens aperture and select the widest aperture your lens allows
2. Camera Motion Blur
How do I know if I have Camera Motion Blur?
Camera motion blur happens around the shutter speeds of 1/30th of a second. This blur can also be affected by the camera lens you are using. Telephoto lenses magnify camera motion blur. The longer the lens, the greater the chance of camera motion blur.
This simple formula comes into use when you are hand-holding a camera.
- 18mm lens = No slower than 1/18th of a second
- 50 mm lens = No slower that 1/50th of a second
- 300 mm lens = No slower than 1/300th of a second
Solution to Camera Motion Blur
3. Inaccurate Autofocus
Solution to Inaccurate Autofocus Blur
- Select focus points manually
- Disable autofocus and focus manually
4. Shallow Depth of Field
Solution to Shallow Depth of Field Blur
- Narrow your lens aperture — instead of f/2.0, try f/3.5 or f/4
- Zoom out — if you're using a zoom lens, make sure it's on its wide-angle setting
- Step back — increasing the distance between subject and lens increases depth of field
Today's Takeaway's and To Do's:
We covered a lot of ground as to why photos may be blurry. Getting this down is going to take practice.
- Read through these details again as listed above and get shooting. This will need a lot of diligent practice to get each of these down. I encourage you to take each scenario and get good at getting the right results.
- look back through your own images that you have taken prior and see if you can pinpoint what type of blur you have ended up with in your images. This will help identify the problems and knowing the solutions to get even better images.
See you tomorrow!
