Basic Photog - Depth of Field
Apr 17, 2013 12:06:59 #
Finally got my wife a decent camera and she's been reading online tutorials and learning quite a bit. I've been doing "photography" since the '70s, so I help her out when I can. One concept she had problems with was Depth of Field. So, while in a neighbor's garden, I set up on a Flowerbed Ledge and took the following. The results are dramatic and now she understands. If you find this instructive, please comment.
High f stop
Low f stop

You've got it. High f stop, greater DOF. You trained her well. Get hey to practice on some stable objects. It's all about aperture.

Phil,
Now that you have given her a good relationship on DOF with the Aperture setting, provide her with a lesson on HFR.
Using Aperture to control the DOF and HFR in combination with Composition can enhance a normally good picture to a work of art.

HDR (High-Dynamic-Range) or did you mean HFR?

HFR (Hyper Focal Range). :-D

Too many acronyms...
HFR = Hyper Focal Range
HFR = High Frame Rate

GoofyNewfie,
It is called HFR (Hyper Focal Range) because you can adjust the point of focus and the depth of focus when creating the image.
Many photo editing programs can simulate the effect, but it looks phoney.
The HFR is considered all points between acceptable focus, and the depth of focus for a selected object in the capture.

PS We really need a good Preview of the scene through the viewfinder without the center spot blacking out as the Aperture closed down. Another advantage of DSLR is the LCD screen showing the capture and magnification of the capture to show where the focus begins to fall off, and take another capture.

I Googled it, and there are some other meanings for those letters.

Never knew that "HFR" was what it was called, but am familiar with the concept. One thing I mentioned to her was that on the OLD mechanical SLR's, there was a way to preview the Depth of Field by holding down the Aperture Close Down lever before pressing the shutter. After all, film was rather expensive to "waste". Anyway, this would let the aperture leaves in the lens close down and though the image in the view finder would darken at higher f stops, you could see what the film plane would see when the shutter was snapped, the aperture closed down and the film was exposed. It's more involved on my DSLR to preview DOF , but is available. How about yours?

Right Jerry,
Just like SS and AP. We have to know the sugject area ot get the right acronym meaning.

Phil,
HFR has been around since the days we could view the image through a single lens reflex viewfinder. We did have an Aperture Preview Button to close down the Aperture to view the DOF the Aperture was going to set.
When our eyes were really sharp and the field of view in the viewfinder was large enough, we could manually reset the focus, to increase or decrease the range of acceptable focus.
In modern DSLR camera bodies we still have this button, it may be hard to find, push, and see the difference in the viewfinder, but it still works. The advantage th modern DSLR provides us is the ability to use "Live View (Canon)" to view the scene live on the LCD panel and magnify the presentation up to 10x. There we can really see the HFR take effect as we manually adjust the ficus ring.
I have an additional advantage, if I need it later, a magnifying eye cup adapter to cover the LCD panel.

All the DSLR's I've owned have this, it is called "Depth of Field Preview" and is typically a button on the front of the camera....same place as the film cameras had it.

Oh, yeah !! THERE it is !! On my wife's new camera, just a small, unmarked button below and to side of lens on the body. Cool !! What's extra nice is that since the viewfinder is electronic, it makes up for the light loss due to large f. Noisy indoors, yes, but view-able. That makes it easier. Thanks for the tip.
