6 Tips For Getting Sharper Photos
1. Center sharpness
Most lenses will produce the most sharpness at the very center of the lens. The closer you get to the corners, the less sharpness you get. If you have an object that you would like to be fully sharp, then you probably don’t want to have it in any of the corners of your frame.
2. 3 stops trick
This is a simple trick that can help you get a bit of sharpness especially is you’re working at very wide apertures like f1.4 or f1.8. The depth of field you get at such an aperture as f1.4 is so shallow that if you focus on the tip of your model’s nose, the eyes could be out of focus. A simple guideline to help you get a good amount of sharpness is to always shoot at 3 or even 2 stops away from the widest aperture.
3. Sweet spot f8
Many lenses have their sweet spot at around f8 and f10. This means that you will get just about the perfect sharpness at this aperture. For a lot of general shots, especially in street photography, this amount of sharpness at f8 is just right. Not too little, and not too much.
This trick works for more general photos where you need to have a good amount of sharpness in your shot. If you see a nice landscape and stop to capture it, this will work for you.
4. AF point selector
With any DSLR now you have the freedom to choose what AF point to use when you shoot. Sometimes you might have it in the center, focus and reframe your shot. This works if your subject is dead still and if you are working with a fairly narrow aperture like f11.
When working with apertures as wide as f1.8 or even wider, it is always important to use an AF point that is set right on onto your desired point of sharpness.
5. Cross type/double cross-type AF Points.
If you have one of the newer DSLR cameras then you probably have some cross type AF points. These focus faster and are more accurate. On a 5D Mark iii has 61 AF points, 41 of which are cross-type. In addition to 41 AF points, you have 5 double cross-type points located at the center of the frame.
6. Shutter speed ISO
If you are shooting in the Av mode and the camera is giving you a slow shutter speed due to low light conditions, you can compensate with a higher ISO to get a faster shutter speed. This works if you are shooting a moving subject in relatively low light.
