Herring Gull photography: shutter speed, lens and crop for herring gulls in flight

The numbers for photographing a Herring Gull in flight, worked out from published wingspan, flight-speed and wingbeat figures: the shutter speed that freezes the wingtips and the body, how many pixels the spread wings fill with 400, 600 and 800 mm lenses at 25, 50 and 100 m, and how far away the bird can be for a 2,048-pixel image or an A4 print.

Short answer: pan with the gull and its body stays put in the frame, so the wingtips set the shutter speed. With its wings across two thirds of the frame on a Canon EOS R7 and 600 mm lens (about 59 m away), 1/2000 leaves the wingtips about 25 px of blur mid-stroke, and keeping them sharp on screen (3 px) takes about 1/20000, beyond the 1/8000 top speed of most mechanical shutters. A burst catches them: at 1/2000, about 1 in 13 frames have the wingtips within 3 px, about 1.6 frames a second at 20 fps. Held still instead, the camera needs about 1/16000 to keep its body within 3 px as it flies across. At 50 m with 600 mm, its wings span 2,842 px on a 24-megapixel full-frame body and 5,307 px on the 32.5-megapixel R7.

Shutter speed for herring gulls in flight

From our shutter-speed calculator with its default setup: a Canon EOS R7 (32.5 megapixels) and a 600 mm lens. You pan with the bird, so its body stays put in the frame and the blur that's left comes from the wings, each taken to sweep a 100° stroke at the bird's wingbeat rate, fastest mid-stroke. Blur is counted in the photo's own pixels at 100%: up to 3 pixels is sharp on screen, 1 pixel is pixel-sharp. The camera-still column is for a bird crossing in front of a camera that doesn't move, at its cruising speed.

Its wingbeat rate is an estimate (sources below), so treat these as close guides rather than exact figures. Holding the wingtips pixel-sharp (1 px) with its wings across two thirds of the frame would take about 1/49,000. The wings stop for an instant at the top and bottom of each stroke, which is why a burst catches sharp wingtips that a single frame usually misses. Stepping back until the wings span a third of the frame halves the blur; crop in afterwards.

Pixels across the wings with 400, 600 and 800 mm

Pixels across the spread wings at 25, 50 and 100 m (at 10 m its wings overfill the frame even at 400 mm), from our reach calculator, on a 24-megapixel full-frame Canon EOS R6 Mark II, a 45.7-megapixel full-frame Nikon Z8 and the 32.5-megapixel APS-C Canon EOS R7:

“Won't fit” means the wings are wider than the frame at that distance. The sum: wingspan × focal length ÷ (distance − focal length) gives the wings' size on the sensor, divided by the pixel pitch (5.98 µm on the R6 Mark II, 4.35 µm on the Z8 and 3.20 µm on the R7). Halve the distance and the pixels roughly double.

How far can you crop?

Most size rules count pixels on the long edge. An image 2,048 pixels wide can come from as little as 35% of the R6 Mark II's 6,000-pixel width, 25% of the Z8's 8,256-pixel width and 30% of the R7's 6,960-pixel width. A landscape A4 print at 300 ppi (29.7 × 21 cm) needs 3,508 × 2,480 pixels: 59% of the width and 62% of the height on the R6 Mark II, 43% of the width and 46% of the height on the Z8 and 51% of the width and 54% of the height on the R7.

Framed the way the reach calculator frames a crop, with the wings across half its width, here is how far away the gull can be and still give you each size, cut from the full-size original with nothing enlarged:

Canon EOS R6 Mark II, 600 mmup to 130 mup to 76 m

Nikon Z8, 800 mmup to 250 mup to 130 m
Canon EOS R7, 400 mmup to 170 mup to 94 m
Canon EOS R7, 600 mmup to 250 mup to 140 m
Canon EOS R7, 800 mmup to 340 mup to 180 m

With its wings across a third of the R7's frame (about 110 m at 600 mm), a crop with the wings across half its width is 4,793 × 3,195 pixels, a 40.6 × 27.1 cm print at 300 ppi. These distances count pixels only; at long range, heat haze and focus cost detail too. Crop from the full-size original, never from a downsized export, and never enlarge a crop to reach a size (how much you can crop a bird photo).

Try it with your own camera

The shutter-speed calculator opens set to the Herring Gull, and the reach calculator to its wingspan; change the camera, lens or distance to see your own numbers.

BirdFrame for Mac finds every bird in a folder or Photos album and crops each from the full-size original, thousands at once, so a day of bursts doesn't mean cropping by hand.

Herring Gull: wingspan 1.4 m (RSPB); cruising speed 13 m/s (Pennycuick et al. 2013); 4 wingbeats a second (est. from size and weight, Pennycuick 1996).

Camera sensor sizes and pixel counts are the makers' published specifications. Every bird is taken to beat its wings through a 100° stroke (est.; 80–130° depending on speed, Park et al. 2001). Values marked est. are estimates.

Questions

What shutter speed freezes a Herring Gull in flight?

Pan with the gull and its body stays put in the frame, so the wingtips set the shutter speed. With its wings across two thirds of the frame on a Canon EOS R7 and 600 mm lens (about 59 m away), 1/2000 leaves the wingtips about 25 px of blur mid-stroke, and keeping them sharp on screen (3 px) takes about 1/20000, beyond the 1/8000 top speed of most mechanical shutters. A burst catches them: at 1/2000, about 1 in 13 frames have the wingtips within 3 px, about 1.6 frames a second at 20 fps. Held still instead, the camera needs about 1/16000 to keep its body within 3 px as it flies across.

How many pixels does a Herring Gull fill with a 400, 600 or 800 mm lens?

Across its 1.40 m wingspan at 50 m, on a 24-megapixel full-frame body: 1,887 px with 400 mm, 2,842 px with 600 mm and 3,805 px with 800 mm. On the 32.5-megapixel Canon EOS R7: 3,524 px with 400 mm and 5,307 px with 600 mm; with 800 mm the wings are wider than the frame. Halve the distance and the pixels roughly double.

How far away can a Herring Gull be for a 2,048-pixel image or an A4 print?

With the wings across half the crop's width, as the reach calculator frames it: with 600 mm on a 24-megapixel full-frame body, up to about 130 m for a 2,048-pixel-wide image and 76 m for an A4 print at 300 ppi; on the Canon EOS R7, 250 m and 140 m. Crop from the full-size original and never enlarge a crop to reach a size.
