Have you been frustrated with the quality of your images? I have a few tips for taking sharper pictures that have helped me over the years.
1. Invest in a high-quality lens, with a low aperture
I shoot with the Sigma Art line (35m, 85m, 135m) and I love the sharpness of these lenses at f/2-2.8.
2. Try back button focus
I noticed an increase in my keep-rate when I started shooting with back button focus. If you want to try this, search your camera body on YouTube for a tutorial of how to set your camera to back button focus. Some people love it, others hate it. Try it out at a practice session or two to see if you can get the feel for it.
3. Increase shutter speed, lower ISO
Motion blur could be a cause. I try to keep my shutter faster than 1/500 and ISO under 500 to maintain a high image quality.
4. Toggle your focus point
If you use the center focus and then recompose, your motion could be a cause of missing focus. I toggle my focus point to the place I want it so that I don’t need to move my camera at all when I press the shutter.
5. Check your eyes
I shoot every session with my glasses on to make sure that I can see everything clearly in camera!
6. Clean your equipment
I use these wipes to clean my lenses frequently. Sometimes fly spray, dust, or dirt can create a film over the lens that makes it difficult to nail focus, or creates a haze to the image.
7. Calibrate your lens
Follow YouTube tutorials if you are missing focus slightly — you might be able to micro-adjust your focus. Personally, I send my equipment in to be professionally calibrated. I send my Sigma lenses to Sigma with the Nikon body so that the lens can be calibrated to the body.
8. Focus before each shot
Because I shoot at a very shallow depth of field, any motion from myself or the subject can result in missed focus. I focus before every time I press the shutter.
