Sometimes, your scene is so deep that it cannot possibly be sharp throughout using normal methods. The way it works is to capture several images shkuld the same scene, but with different points of focus.
Then you open all the images in post-processing software and stack them together—for one ultra-sharp result!
In fact, some macro focus stacking projects literally require dozens, or even hundreds, of shots. The hyperfocal distance is the point of focus that maximizes the depth of field. No, definitely not!

I am a sucker for those landscape photos which have a prominent object in the foreground with beautiful scenery stretching away into the far background. And both the near object and the far background are in focus. Or we can look to this information poster and try to figure out what settings we can experiment with:.
Well, not quite. That says that everything from half that distance about 3. But my rock is 3 meters away, so it would not be in acceptable focus.
What can I do? Closer — everything from about 3 m 9 cm away from the camera to the far background would be in acceptable focus. Unfortunately, my rock, 3 m away, would still be fuzzy. Or, I could look at adjusting the focal length a little bit. Let me move my zoom setting to 70 mm and make sure the scene still looks good I am making the composition just a little bit wider and taller, so I want to make sure I am not including more of the closer foreground.
Now when I do the calculation I get:. So, if I focus on a point which is 5. How do you set the focus to 5. Most lenses have a scale on their focal ring enabling you to set the focus at a particular distance. If you have to estimate where the 5. As might be expected, there is an app for all of this.
But I have to confess that I would mentally estimate 5. To make it somewhat easier by having H come out in feet, I could have used the simplified formula:. That would have given, respectively, Our rock is 3 m away just under 10 feet so anything less than 20 ft for the hyperfocal distance H works.
The correct formula is:. But, if you are doing macro photography, the omitted term may be important. You might also think that a focal length of 72 mm is awfully long for a landscape photo. So, what problems are we going to face as a result of these new conditions? In other words, going to wider angles shorter focal lengths actually makes it easier to find the focus point which will meet all our conditions.
None of my lenses has a distance scale and I do not have an iphone or ipad. To date, my solution has been to take lots of shots with different focal lengths and focal points. Not very high tech, very time consuming and often very frustrating.
