Nuts (and Bolts) Examples of Depth of Field

What’s Up?

I will be without internet access from 8 AUG through late in the day on 22 AUG. There will be a brand new educational blog post every day in my absence. I toiled long and hard on August 6th and 7th to make that happen 🙂

Please call the office at 863-692-0906 on weekdays and speak to Jim and Jennifer about all things BAA Online Store- and IPT-related. And anything else that you might need help with or would like to chat about.

Please continue to patronize the BAA Online Store and to use my B&H affiliate links. Both are hugely appreciated.

with much love, artie

The Streak

Today marks twenty-six days in a row with a new educational blog post. This blog post took about two hours to create.


Booking.Com

I could not secure the lodging that I needed for the UK Puffins and Gannets IPT in Dunbar, Scotland, so I went from Hotels.Com to Booking.Com and was pleasantly surprised. I found the rooms that I needed with ease at a hotel that was not even on Hotels.Com, and it was a nice hotel that I had seen in person. And the rates were great. If you’d like to give Booking.Com a shot, click here and you will earn a $25 reward.

Thanks to the many who have already tried and used this great service.

Revamped

I finally updated the IPT page to properly reflect the recently completed trips. If you doubt that I am really slowing down do click here to see the meager IPT schedule. Right now there are only two US-based IPTs on the schedule. Best news is that I turned up the missing registrant for the Fort DeSoto IPT so that will run. Do consider joining us if you would like to learn from the best.

Photographers Wanted

If you would like to learn to be a better bird photographer, consider joining me on either the Fort DeSoto IPT in late September or the San Diego IPT in January, 2018. With just one person signed up, DeSoto will offer practically private instruction. And you can tack on the In-the-Field/Meet-up Workshop Session on the morning of Tuesday September 26, 2017 for free. Click here for IPT info and the current but abbreviated schedule.



Gear Questions and Advice

Too many folks attending BAA IPTs and dozens of folks whom I see in the field, and on BPN, are–out of ignorance–using the wrong gear especially when it comes to tripods and more especially, tripod heads… Please know that I am always glad to answer your gear questions via e-mail.

Please Don’t Forget …

As always–and folks have been doing a really great job for a long time now–please remember to use the BAA B&H links for your major and minor gear purchases. For best results, use one of our many product-specific links; after clicking on one of those you can continue shopping with all subsequent purchases invisibly tracked to BAA. Your doing so is always greatly appreciated. Please remember: web orders only. And please remember also that if you are shopping for items that we carry in the BAA Online Store (as noted in red at the close of this post below) we would of course appreciate your business.

nut-at-f-2-8-_P3A8845-Palouse,-WA

This image was created on the 2017 Palouse IPT with the Induro GIT 304L/Mongoose M3.6-mounted Canon EF 100mm f/2.8L Macro IS USM lens and my favorite bird photography camera body, the Canon EOS 5D Mark IV. ISO 400. Evaluative metering +2 stops: 1/100 sec. at f/2.8 in Av mode. Daylight WB.

I used my still flower technique: Live View (for mirror lock-up) and the 2-second timer. Flexi-zone AF with the square right on the KS.

Image #1: Nut (I think it’s a nut …) on old farm machinery

Depth of Field at f/2.8

Notice that at f/2.8 only the top of the nut is in sharp focus.

nut-at-f-16-_P3A8845-Palouse,-WA

This image was created on the 2017 Palouse IPT with the Induro GIT 304L/Mongoose M3.6-mounted Canon EF 100mm f/2.8L Macro IS USM lens and my favorite bird photography camera body, the Canon EOS 5D Mark IV. ISO 400. Evaluative metering +2 stops: 1/3 sec. at f/16 in Av mode. Daylight WB.

I used my still flower technique: Live View (for mirror lock-up) and the 2-second timer. Flexi-zone AF with the square right on the KS.

Image #2: Nut (I think it’s a nut …) on old farm machinery

Depth of Field at f/16/h3>

Notice that at f/16 the depth of field has increased tremendously. Note only is the top of the subject in sharp focus but the cracks in the paint and the blemishes on the machinery are all rendered sharp.

This principle comes into play in bird photography when you stop down even a bit, to f/8 or f/11, you will –depending on the distance to the BKGR — bring up unwanted background detail.

Your Choice?

Which of the two images do you like best, the one at f/2.8 or the one at f/16?

If you have any ideas on combining the two images, please share them by leaving a comment.

    Artie, thats a bolt (the head of the bolt) . If it were a nut, the bolt would be seen protruding from it ; )

  • So please relate this to bird photography. I have a mother bluebird feeding a baby a worm, and a second baby behind them. Is there some magic guide for depth of field to get all birds on two different planes in focus? Wide open gives a sharp focus on most of mom and first baby, but baby 2 is out of focus. Which is ok if you want that, but I want all 3 birds in focus with with as blurry of a background as I can get. Is f/8 the answer?

    I think the nut was behind the camera! No, No, please …. just joking!

    Artie, it is a bolt head. The three radial lines indicate its strength – Grade 5, a medium strength fastener which is required to be heat treated, quenched, and tempered to obtain the desired strength. The marking KS is supposed to be the manufacturer’s mark but, according to a website is a suspected counterfeit. See http://www.web.anl.gov/PRO/Genetal%20Information/webforms/suspect.pdf

    Hi Artie. I think I prefer the stopped down image. The cracks in the paint are added texture for me that helps tell the story.
    And what you have there is the head of the bolt rather than the nut which will be on the other end.
