Happy Friday! And welcome to this week’s installment of Thank Goodness it’s Foto Friday! Today I’d like to talk about my techniques for getting tack sharp images with very wide apertures, like f/1.2, f/1.4, etc.
Into the Great Wide Open
Shooting with very low apertures (like 1.4) creates absolutely beautiful, atmospheric images. Where just one small, yet important area is in focus and everything else fades into a soft blur, also known as bokeh. These f/stops can be difficult to work with. Below are my tips for attaining sharp focus with wide apertures.
My Top 5 Tips for Shooting with Wide Apertures
Like many things I’ve learned my technique for shooting with wide apertures through trial and error…lots of error. Through that error I have found my top advice for getting tack sharp images at f/1.4.
1. I set my focus mode to Continuous Focus. I love having Continuous Focus set when shooting with low f/stops because it is constantly adjusting focus, which is great because if your subject moves just a hair continuous focus mode will adjust for that and thus give you a sharp image.
2. I set my AF Sensor Mode Switch to multi-point. I then take my focus point and align it over, for example, my subjects eye. Having the focus point exactly where I want it is crucial to getting tack sharp images with low f/stops.
What happens when the area you’d like in doesn’t land in one of the focus points? The best way to adjust for that is to focus with that point on your subject and then very carefully shift on a straight plane either horizontally or vertically based on your composition. You want to keep your lens on an imaginary flat plane when doing this technique so that your distance to your subject doesn’t change. If you happen to angle your camera up or down – you have now changed the distance to your subject, which means the image will be out of focus.
3. Distance is a factor. The closer you are to your subject = less depth of field. Which means it will become more difficult to get a tack sharp image as the area of sharp focus may be down to millimeters. Conversely, if you move away from your subject your area of focus will increase. For a very precise and techy manual you can check out this depth of field calculator – here.
4. Take into consideration the amount of light hitting the lens. If you are shooting back-lit, with lots of sun flares, that flood of light will reduce your area of focus greatly.
5. Practice, practice and then practice some more
