How Large a Crop?

What’s Up?

I have been able to stay up every day till between 8 and 9pm with only a short nap and I have been able to get lots of work done during the day without feeling like a zombie. The problem remains that I have been getting up between 2:30 and 3:00am. You gotta love jet lag.

I am starting to think about packing for the upcoming 2019 Galapagos Photo-Cruise of a Lifetime IPT. So far, my cell phone has not been turned in to the EDI (Edinburg, Scotland Airport) lost and found.

Selling Your Used Photo Gear Through BIRDS AS ART

Selling your used (or like-new) photo gear through the BAA Blog is a great idea. We charge only a 5% commission. One of the more popular used gear for sale sites charged a minimum of 20%. Plus assorted fees! Yikes. They went out of business. And e-Bay fees are now up to 13%. The minimum item price here is $500 (or less for a $25 fee). If you are interested please scroll down here or shoot us an e-mail with the words Items for Sale Info Request cut and pasted into the Subject line :). Stuff that is priced fairly — I offer pricing advice to those who agree to the terms — usually sells in no time flat. Over the past year, we have sold many dozens of items. Do know that prices on some items like the EOS-1D Mark IV, the old Canon 100-400, the old 500mm, the EOS-7D, and the 7D Mark II and the original 400mm DO lens have been dropping steadily. Most recently the price of used Canon 600mm f/L IS II lenses have been dropping like a rock with the introduction of the 600 III. You can always see the current listings by clicking here or on the Used Photo Gear tab on the orange-yellow menu bar near the top of each blog post page.

As used gear sales have slowed a bit in recent months — especially with dSLR bodies, there are lots of great buys right now both below and on the Used Gear Page.

New Listing

Canon EF 400mm f/4 IS DO II Lens

BPN-friend Robert Kimbrell is offering a Canon EF 400mm f/4 IS DO II lens in near-mint condition for the BAA record-low price of $4199.00. The sale includes the tough front lens cover, the rear cap, the lens strap, the lens trunk, the original product box, and insured ground shipping via major courier to lower 48 US addresses only. Your item will not ship until your check clears unless other arrangements are made.

Please contact Robert via e-mail.

I owned and used the 400 DO II when I shot with Canon and found a way to take it on most trips. I took it to Scotland and Nickerson Beach and San Diego. It served me well as my (lighter!) big gun several Galapagos and Southern Ocean (the Falklands and South Georgia) trips. It is a killer for flight with or without the 1.4X III TC. It is. razor-sharp with the 2X on static subjects and skilled folks have had amazing success hand holding it with the 2X III TC for flight and for action. artie

Gear Questions and Advice

Too many folks attending BAA IPTs and dozens of photographers 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. Those questions might deal with systems, camera bodies, accessories, and/or lens choices and decisions.

This is a crop of an image that was created on the morning of June 5, 2019 down by the lake near my home. Working while seated in the front seat of my SUV, I used the Induro GIT 304L/FlexShooter Pro-mounted Nikon AF-S NIKKOR 600mm f/4E FL ED VR lens, the Nikon AF-S Teleconverter TC-14E III, and the mega mega-pixel Nikon D850 DSLR. ISO 400. For the uncropped original, matrix metering at about +2/3 stop: 1/800 sec. at f/7.1 in Manual mode was perfect with the histogram pushed all the way to the right. AUTO1 WB at 7:45am on a sunny morning with a very light cloud in front of the sun.

Nikon Focus Peaking fine-tune value: a very significant +9. See the Nikon AF Fine-tune e-Guide here.

One up and two to the left of center Dynamic 9 points (d-9) Continuous (C in Nikon/AI Servo with Canon) AF was active at the moment of exposure. In the original frame, the selected AF point was on the bottom right of the bird’s neck.

The FlexShooter Pro From the Car

Working with the FlexShooter Pro from the car or anywhere else is a dream. It’s a ballhead that thinks its a gimbal head. After one simple adjustment, all of your images will be square to the world. Your big lens will stay right where you point it. And I have done lots of flight photography from the driver’s seat of my Sequoia. It is simply amazing. Learn more about working off the FlexShooter Pro from your vehicle in the blog post here.

FlexShooter Pro Update

We currently have FlexShooter Pro heads in stock here. We have all but one of the BigFeet in stock but are sold out of the new FLN-60 BigFoot that was recently re-designed for the Nikon 600 VR. Click here to access the pretty much complete FlexShooter Pro story with videos.

Setting the Tripod Up in the Vehicle/Best by far with the FlexShooter Pro

The Setting up a Tripod in your Vehicle MP4 Video

$10 here in the BAA Online Store or free with your purchase of the life-changing FlexShooter Pro Head.

This seven-minute video will teach you exactly how to set up a tripod in most vehicles. You can do this with pretty much any tripod that does not have a center post. It is just one of the many reasons that I do not like or use a tripod with a center post. As I did for more than two decades, you can use this strategy with any ballhead or with a Wimberley V2 head or a Mongoose M3.6 action head, but the FlexShooter Pro has several huge advantages. First and foremost you are able to level the large silver ball. This enables you to pan with moving subjects and shoot action and even flight from the driver’s seat of your vehicle all while the camera remains 100% square to the world, aka “level.” The second big advantage is that the FlexShooter Pro has a lower profile than either of the other two heads mentioned so that you can be low enough to work subjects on the ground that are relatively close to your car.

You can order your copy of this MP4 video here in the BAA Online Store. It is free with the purchase of a FlexShooter Pro head. Those who have previously purchased the FlexShooter Pro from us can e-mail to request their free copy.

Bosque del Apache 2019 IPTs

Notice the incredible variety of images that you can learn to make by developing your skills and your creative vision on a BAA IPT.

2019 Bosque del Apache IPTs

Return to Bosque Reduced Rate Scouting IPT #1. NOV 26-28, 2019 — 3 FULL DAYS: $1199.00. Limit: 8/Openings: 7. Introductory Meet and greet at 7pm on MON 25 NOV.

Return to Bosque IPT #2. NOV 29 (afternoon session thru DEC 4 (morning session) — 5 DAYS (4 full and two half): $2249.00. Limit: 10/Openings: 9. Introductory Meet and greet at 2:00pm on FRI 29 NOV.

I quit going to Bosque several years ago as conditions had worsened each year for several seasons running. My understanding is that things have improved dramatically in recent years. Photography-wise, I know Bosque better than anyone. Join me to learn how wind and sky conditions influence bird photography, how to create dramatic sunrise and sunset silhouettes, how to be in the right place at the right time, and how to create contest-winning blurs. As usual, you will learn to get the right exposure every time, to use your camera’s AF system to create pleasing, balanced image designs, and to improve your flight photography skills.

We should get to photograph many thousands of Snow Geese, more than a few blast-offs, some Ross’s Geese, and lots of Sandhill Cranes in the water, taking flight and flying. Depending on local conditions we may get to shoot some ducks: point-blank American Wigeon and Wood Duck. With any luck, we might enjoy sunrises and sunsets that leave you in tears. Live, eat, and breathe photography with one of (if not the) worldโ€™s premier photographic educators at one of his very favorite locations on the planet. Top-notch Photoshop instruction. Join me to learn to think like a pro and to recognize situations and to anticipate them based on the weather. Every time we make a move, I will let you know why. When you get home, applying what you learned will prove to be invaluable.

Both trips will run with only a single registrant. Lunch is included on all full days of each workshop.

Free Morning Session

Sign up for either IPT and enjoy a free morning session on Friday, 29 NOV.

$500 Multiple IPT Discount

Join me for both IPTs and we will be glad to apply a $500 multiple IPT discount.

To Register

To register, send your non-refundable $500 deposit — check made out to BIRDS AS ART — via US Mail to PO Box 7245, Indian Lake Estates, FL 33855. Or call Jim weekdays at 863-692-0906 to put your non-refundable deposit on a credit card. Balances must be paid in full by check no later than three months before the IPT. If you cancel, all but your deposit will be refunded only if the IPT sells out.

Travel Insurance

Travel insurance for both big international trips and US-based IPTs is highly recommended as we never know what life has in store for us. I strongly recommend that you purchase quality travel insurance. Travel Insurance Services offers a variety of plans and options. Included with the Elite Option or available as an upgrade to the Basic & Plus Options you can also purchase Cancel for Any Reason Coverage that expands the list of reasons for your canceling to include things such as sudden work or family obligation and even a simple change of mind. My family and I use and depend on the great policies offered by TIS whenever we travel. You can learn more here: Travel Insurance Services. Do note that many plans require that you purchase your travel insurance within 14 days of our cashing your deposit check or running your credit card. Whenever purchasing travel insurance, be sure to read the fine print carefully even when dealing with reputable firms like TSI.

    Hi, Artie. I agree with your assessment; your site is a really good place to sell used camera gear.

    The D850 is so good that it’s hard for me to guess. Cropping away 98.3 percent of the pixels seems unreasonable, though. So I’ll guess 88.3 percent.

  • John Mack: did you click on the image to see it in higher resolution? Makes a huge difference.

    • avatar Arthur Morris/BIRDS AS ART

      Thanks, John. I am not sure why the enlarged images usually look sharper than the posted images. The view here is at about 220%. For such a big enlargement, the image looks quite sharp to me.

      with love, artie

    Agree, A. Interesting exercise.

  • Hey Arthur, A 98.3% not much detail in those feathers and the image does not look tack sharp.

    • avatar Arthur Morris/BIRDS AS ART

      Hi John,

      Thanks for commenting. I disagree. Do you ever look at your images at 220%?

      with love, a

      ps: see the suggestion above by John Armitage.

  • avatar Joel Eade

    The answer is A … more than 98% of the original pixels were cropped away:

    The displayed image is 880 x 880 (pixels) = 774,400

    774,400 / 45,000,000 (pixels on the full sensor) = 0.01720889

    So only 1.720889% of the original number of pixels remain.
