How to focus in macro
Today I want to share with you a very simple tip, because I realized very recently that everyone does not necessarily know her and that it could save you in certain situations.
This trick is to get a good focus when taking macro or proxiphoto photos, that is to say very close-up photos, in fact very close-ups.
In this situation we have a small problem, which is that the depth of field is very low, because even if we have a relatively small aperture and we have closed the diaphragm a little, we still have a depth of field which is, in general, really very small. And it's even worse if we open the diaphragm as far as possible, for example if we are in low light at the same time.
So the problem is that we really have a tiny depth of field, which can be on the order of a millimeter, and we can very easily have a blur of focus on the photo, even using the lens. autofocus.
Because all you need to do is move between when you focus and when you shoot, and the picture will be blurry.
So, this is a concern that can arise for many of you as soon as you take this kind of image.
And in fact, the solution for once, is not to use the focus automatically , but to make a development manual .
You put your camera in manual focus and turn the focus ring until it stops on the near side , because you usually have two stops on the focus ring. You have the focus side stopper as close as possible and the focus side stopper at infinity.
So you are focusing as closely as possible; if you do not have the indicator on your lens, it is easy: if you focus on infinity you will see an image which will be sharp far away and blurry near, and vice versa.
So you just have to focus on really the minimum focus distance , where you can get closest, and then, rather than using autofocus, in fact you're going to step forward or you. move away from your subject. So actually, you approach or walk away with your device until it is clear in your viewfinder or on the screen.
In fact you have to be fairly reactive, that is to say that you stabilize yourself well , you advance very slowly or you retreat very slowly until it is clear, and as soon as it is clear we trigger. Because obviously, if you see that it's clear and you wait 10 seconds, you have a nine in ten chance of moving in the meantime and the photo is blurry, so we come back to the same problem as the previous problem.
The trick really is to approach or step back . I know some already know this, but for those who don't, it can really save you a lot of time and allow you to take sharp photos. Check for more on https://www.dzoptics.com/en/
Sometimes it will take several tries , sometimes you will still fail and you will have a photo that will still be slightly blurry in focus, but also remember to take a burst ; if you take a burst of 3-4 photos and are already pretty much in focus while on the move, you will normally have good results.
I tested this just last week on some photos that I'll probably show you in September when I'm done sorting and developing them, and it worked really, really well.
