Hello Everyone. Today in this Blog I am going to talk about focus stacking. Do Read the whole blog to get detail information on Focus stacking.
1) What is Focus Stacking
Basic concept is focusing on different areas and stacking meaning combining those images in post-processing. But how to do it. Why to do it. That’s what I am going to cover in today’s blog. It’s going to be a super fun and an informative blog.
If there are multiple subjects in a frame at different planes, everything won’t be in focus if you’re using a wider aperture. As you start using a smaller aperture, the depth of field increases and you start getting more things in focus.
2) When to use Focus Stacking
So, if you want everything in focus, just use a very small aperture. Something like f 16 or f 22 and the problem is solved. Right ? WRONG. When you start using apertures smaller than f 10 like f 14 f 16 f 22, the sharpness of the lens tends to reduce.
Every lens has a sweet spot and after that the sharpness reduces gradually so. Even if at f 22 everything is in focus because the sharpness has reduced the quality is affected.
In low light situations, using a smaller aperture every time is not an ideal situation. We want everything to be in focus but we also want optimum image quality. for that the solution is obviously focus stacking.
3) Major Aspects of Focus stacking
This process involves two major steps shooting and editing. Let’s talk about shooting some images. First, shoot a landscape and were you have a foreground, mid-ground and background.
One thing that you should keep in mind is to always use a tripod because we are going to shoot multiple images and we want them to be perfectly aligned. Use manual mode. You don’t need settings to change focus on the foreground.
Take the image same with the mid ground and background. There is no rule on how many number of images you have to take. It depends on the situation. Sometimes you might even need to shoot more than 10-20 images depending on the situation. And a lot of macro and product photographers do that.
What exactly is in focus and will only use that part. You can also later make manual adjustments to mask if needed to add some more sharpness. Also, Use a high pass filter. Change the blending mode to overlay and use masking to paint the areas which you want to be sharpened.
That’s it from this blog guys. I know this was a slightly advanced technique but if you use this technique in right situations you can create amazing high quality detailed images.
