Fast shutter speeds for slow and faster flying birds

Fast shutter speeds for slow and faster flying birdsFast shutter speeds for slow and faster flying birds - and one experimental slow shutter speed capture

Yesterday I briefly discussed the effect of slow shutter speeds on relatively fast movement subjects for creating motion blur in some of the moving parts (the areaoplane and the motorcycle) - capturing them with shutter speeds of between 1/60s - 1/125s if the objective of the photographer is to show motion blur (in i.e. the propellers and wheels).

With birds in flight photography it is generally quite the opposite: the objective is to freeze the motion of the bird in flight (main areas are the wings, heads and sometimes a few water drops as well).

The shutter speeds used for the 3 birds: the first two fast and the third bird is an application of a slow shutter speed of a medium-fast bird.

Image 1: for the little egret (a relatively slow flying bird) I used a shutter speed of 1/3200s with an aperture of f/5.6 (using Manual Mode). The shutter speed is responsible for stopping the motion and the aperture at f/5.6 is to provide sufficient background blur - the out of focus area between the bird and the background.

Image 2: for the pied kingfisher (a very fast and at time erratic flyer and diver) I used a fast shutter speed of 1/5000s to ensure stopping any motion of the bird and the water. I used an aperture of f/5.6 (using Manual Mode). The background in this image was slightly less blurred than image one as the subject here is very close to the water and the blurring effect with the Canon EF 400mm f/5.6L USM lens at f/5.6 is less effective at a shorter background range).

Image 3: this is an experimental / abstract capture for showing a slow shutter speed on a relatively fast flying bird (white-breasted cormorant). Shutter speed was pre-set in Tv Mode at 1/60s.

To be safe, for most bird speeds, I use an average shutter speed of 1/3200s - 1/4000s. Lower in lower light and higher in good light / fast flying birds.

Note on ISO and Shutter Speed: I use Auto-ISO in Manual mode for all my birds in flight photography and with higher shutter speed comes higher ISO''s for my ideal exposures - i.e. if you are achieving an ISO of 400 with a shutter speed of say 1/3200s and you move to 1/4000s the ISO will move one stop more to ISO 640 or 800 (depending on your camera's ISO settings). In low light the ISO (when using Auto ISO) could go even higher.

Most entry-level DSLRs can only achieve a maximum shutter speed of 1/4000s. Higher-end models are capable of achieving shutter speeds of 1/8000s. For most birds in flight / fast action a shutter speed of up to 1/4000s should be fast enough for stopping the motion.

All three images captured with Canon EOS 7D Mark II / EF 400mm f/5.6L USM lens at Woodbridge Island.

Small Birds with Birds in Flight Photography Settings

Pied Kingfisher - Perched Birds Photography - Table Bay Nature Reserve Woodbridge Island
Photographing perched small birds 
With all the questions I get with regard to my perched small bird photography technique (with my standard Bird in Flight photography settings), I thought it was about time to provide more detail regarding settings et al.

For many new and experienced photographers this is a different way of shooting perched birds. Generally one will assume that perched birds will be photographed with a long lens (with Image Stabilization) and / or on a tripod (or some other form of stabilization).

During my own skills development process with Birds in Flight photography I would at times encounter a few smaller perched birds (in the Table Bay Nature Reserve close to Woodbridge Island). I used to ignore them at first, as I was on a mission for fine-tuning the Canon EOS 7D Mark II's AF and to master my Birds in Flight photography techniques. The smaller birds around the Table Bay Nature Reserve / Woodbridge Island are rarely perched for more than a few seconds at a time - I quite like this unpredictability, as its making the capturing more natural (as in the the true wild).

Early one morning in the goodness of our local summer light I captured a few smaller birds without changing any settings on my camera - with the understanding that the fast shutter speeds that I generally use - 1/3200 - 1/4000s - should work to stop (any) motion and the good light should keep my Auto-ISO in manual mode down. My lens does not have Image Stabilization and I'm quite experienced in its application for Birds in Flight photography. These days I rarely change any settings for the perched birds as I don't really see any real advantages over using any other settings (i.e. Av Mode with lower ISO's),

The images posted here are generally all with the same settings without any changes to my Birds in Flight photography settings. The only exception is, when I have enough time, I would change my standard large Zone AF mode to one of the smaller AF areas.

Vintage Cameras and Accessories - Milnerton Flea Market
Saturday at the Milnerton market...
A hotchpotch of colours, textures, goods and just about everything at the Milnerton Flea Market.

This Flea Market is not just about 'one man's junk is another man's treasure', there are various traders selling handmade African craft works, secondhand books, textile and various stalls of fresh produce and refreshments.

I have found the table with all the old film cameras and accessories particularly interesting and will definitely go back for another look.

The Milnerton Flea Market seems to be well organised with clear trading policies and communication between the traders and the Flea Market site management. I've spent some time discussing various bits of trading and other information and received very positive feedback on well organised trading environment and conditions.

Shooting Birds in Flight at higher ISO’s / moodiness of poor light

Little egre in flight - Canon EOS 7D Mark II
Little egret in flight - Canon EOS 7D Mark II - Woodbridge Island @ ISO 1600

My students know that I’m an great believer of Auto-ISO on all DSLR's in my bag (for Birds in Flight photography.) On this occasion (a while before Covid) I looked out the window and observed ISO weather of between ISO 1200 – 3200. A bitterly cold and horrible day for anything outside let alone Birds in Flight Photography. Normally on a day like this, I will evaluate my opportunity cost options and rather do something else.

But, I had a new client, super keen on testing out his brand new kit (body and lens) and I had little choice but to assist him in his quest for mastering application / practice. I did however, offered him coffee (instead) on Woodbridge Island before this shoot, but the lad wanted to shoot – so off we went.

Herewith one of the images I managed to capture with my traditional Birds in Flight settings on that day - remember I deliberately selected Auto-ISO to see the results. EXIF Data: ISO 1600 / f/5.6 / 1/2500s.

Thoughts on planning / atmospheric conditions for photographers

Image Copyright Vernon Chalmers: Notes on planning and application for the serious photographer
Earlier this morning I posted about a question of any 'Photoshop' applied in one of my in-flight images - with the intention of asking if the image was manipulated in any way.

Read: Bird in Flight image photoshopped or not?

As a photographer I am a little concerned that people would think like that, but nevertheless see it as a compliment - especially where the photographer planned for achieving specific results.

For my own birds in flight photography around Woodbridge Island, Cape Town I look at two environmental variables very seriously: (i) available morning light and (ii) atmospheric conditions (wind / sun / clouds et al) before going out for a session.

My 'check' for best value photography is seen in the attached image: for the absolute best conditions this is what I look / plan for (when I look out the window). So its quite possible that some people may think Photoshop played any role in the outcome of certain images.

Unfortunately, days like this on the image is far and few between. I wait it out and when the going is good, I get going. It doesn't mean we don't should around here in any other conditions.

It is also important to note that the serious photographer should be able to shoot in many different light conditions. Light is probably our biggest advantage, but without appropriate light, the challenges will increase thinking and planning (without rushing out to purchase higher-quality equipment).

We all use different levels of post-processing . I believe the serious photographer will (only) attempt to improve the well-planned shot in terms of slight adjustment(s) in the exposure and / or the composition, without altering the original 'naturalness' of the image.

Introduction to the Photography Exposure Triangle

Introduction to the Exposure Triangle: ISO / Aperture / Shutter Speed
Canon EOS 70D / 300mm Lens ISO 100 f/13 1/125s
Exposure:  ISO / Aperture / Shutter Speed

The objective of this article is to provide new photographers (irrespective of camera brand or model) with an introduction to the Exposure Triangle and the inter-relationship between the three fundamental exposure elements:
  • ISO
  • Aperture 
  • Shutter Speed 

Camera / Lens EXIF Data
EXIF Data is the identification and listing of an information tag and its value (available for DSLR / Compact / Smartphone cameras after taking the photo) - generally found on your LCD screen viewing image detail or when downloaded in Google Picasa / Adobe Lightroom (and other camera / editing software). Read more>>


Introduction to the Exposure Triangle
Every photo taken with a DSLR / Compact / Smartphone camera will offer / use a variety of settings to expose an image as ideally as possible to the photographer’s vision and planning.

Exposure Triangle
Introduction to the Exposure Triangle: ISO / Aperture / Shutter Speed

Exposure Process
Exposure is a photographic process of light reflecting off a subject through the camera lens onto the camera's image sensor for a specific period of time. The relationship between ISO, Aperture and Shutter Speed settings will determine the final exposure of light (for each image) captured by the camera's image sensor - and will represent a given Exposure Value (EV).

Relationship between ISO, Aperture and Shutter speed
In understanding ISO, Aperture and Shutter Speed it’s important to note that all three are present in every photo you capture with your camera. The degree in which they are applied will depend on various camera and / or lens settings and lighting conditions. The main camera control over the inter-relationship between the three will be decided by the photographer in selecting the most appropriate shooting mode (in Auto Mode the camera will select the exposure settings, with limited other manual / photographic control).

Aperture demonstration for new photographers View

In most cameras today you will not find ISO / Aperture / Shutter Speed settings on the main mode dial of the camera, but either as separate switchgear or tucked inside the menu system – to be used with other settings (when selecting your shooting mode (Auto / P / Av / Tv / M Mode).

Auto-ISO is also an option that many new and experienced photographers are using.


Photographic Genres and the Exposure Triangle
As we developed as photographers we learn how to properly set the exposure for different genres. With Birds in Flight (action) a fast enough shutter speed will be a priority, for a distant landscape the attention / focus will be on a smaller aperture / f/stop. In long exposure / night photography we would like to keep the ISO as low as possible to minimize noise, but may opt for a 30 seconds or longer expose (ito of shutter speed). At all times all three settings of the Exposure Triangle will be configured to assist the photographer with the type of exposure required.

Camera Shooting Modes
In Automatic Mode the camera will decide the exposure settings for the photographer, in the Semi-Automatic Modes (Av / Tv) the camera will decide at least one exposure setting and in Manual Mode the photographer could take full control of all three exposure settings - many photographers who prefer Manual Mode may leave the ISO on Automatic and only set the aperture and the shutter speed.

P Mode Canon PowerShot SX40 HS f/5.6 ISO 100
P Mode: Canon PowerShot SX40 HS f/5.6 ISO 100
All DSLR cameras and the more advanced compact cameras will have at least the following shooting modes in which the ISO / Aperture / Shutter Speed exposure setting will be automatically / manually controlled by camera and / or the photographer:

Auto Mode
In Automatic Mode the camera will decide the best exposure and the photographer will have no control over any ISO / Aperture / Shutter Speed settings. Best use: when new to photography and / or uncertain about setting in changing light conditions.

Program (P) Mode
In P mode the camera will control Aperture and Shutter Speed with the photographer full control over ISO settings. Best use: when new to photography, shooting in changing conditions, but have control over ISO settings. Program (P) Mode demonstration Canon PowerShot SX40 HS

Aperture Priority (Av) Mode
In Av mode the camera will control Shutter Speed with the photographer full control over Aperture and ISO settings.

Best use: when controlling aperture settings for Depth Of Field (DOF) application in ie. macro / landscape / portraiture / street photography. seascapes / Table Mountain photography Canon EOS 6DCanon EOS 700D DSLR


Shutter Priority (Tv) Mode
In Tv mode the camera will control Aperture with the photographer in full control of Shutter Speed and ISO settings.
Best use: when controlling shutter speed for subjects in motion or to freeze motion of birds, people and other objects. Motor Sport / Action photography 
Canon EOS 70D DSLR / Canon EOS 700D DSLR

Manual (M) Mode
In M mode the photographer will have full control over ISO, Aperture and Shutter Speed settings.

Best use
: when the photographer requires full manual control over all three settings in specific environments in ie. studio, changing light or other challenging conditions. Birds In Flight photography Canon EOS 7D Mark II / Canon EOS 70D /  Canon EOS 70D DSLR

Interpretation and interaction of these exposure EXIF data readings:


ISO

P Mode: EOS 700D / 10-18mm Lens IS0 800 f/4.5
ISO is the abbreviation for International Standards Organisation and an indicator of the sensitivity of light entering the lens onto the sensor. Its measured in values of ISO 50, 100, 200, 400, 800, 1600, 3200, 6400 and 12 800. Most cameras will also have an option for Auto-ISO. More advanced / professional digital cameras could have and ISO of up to ISO 51200+ (ie. Canon EOS 1D X). Most cameras including compact cameras will give an ISO range of 100 – 6400+ which is suitable for most lighting conditions.

ISO 100 is generally the setting used for outside / bright light photography and will be set higher as outside natural light or internal artificial light deteriorates. Not uncommon to set ISO 400 for indoor lighting and up to ISO 1600 for outside / low light photography. These various ISO settings are available for the photographer to adjust
for low light photography – even to leave the camera on Auto-ISO (for changing daylight / overcast conditions). It is recommended to experiment with ISO 400 - 1600 for after dark / night photography. When doing long exposures (slow shutter speeds) it is recommended to use ISO 100 - 400. Higher ISO demonstration Canon EOS 700D DSLR

Recommended ISO settings:

  • ISO 100 or 200 for sunny and bright daylight 
  • ISO 400 ISO for cloudy days, or indoors 
  • ISO 800 for indoors (without a flash) 
  • ISO 1600+ for very low light situations 

Disadvantages of high ISO settings:

  • More noise visible in the image the higher the ISO value
  • Higher ISO’s affects slower shutter speeds (for possible camera shake if handheld)

Aperture
Introduction to the Exposure Triangle: ISO / Aperture / Shutter Speed
Image 2 - Av Mode: f/5.6 ISO 400 1/90s
Aperture is the size of the space in which light enters the lens / camera. It is measured in f/stops - a fractional formula used for allowing a certain amount of light in - ie. f/5.6 or f/11 which is controlled by the photographer via a variety of ways ie. manually daing it in Av or Manual mode on the camera body). In Auto or P mode (and Tv Mode) the camera will decide the aperture for you). Aperture is (also) used to control Depth Of Field DOF). DOF / close-up photography in Av mode Canon EOS 700D DSLR 

Aperture values

f/1.8  f/2.8  f/4  f5.6  f/8  f/16  f/19  f/22 f/32 (This is lens 
dependent on a DSLR camera system, but in most cameras the setting will be on camera body).

Deep vs; Shallow Depth-Of-Field (DOF) 
With a deep DOF more of the entire image will be in focus and its more likely
to be used in Landscape Photography with smaller apertures of ie. f/11 – f/16.
With shallow DOF certain areas of an image is deliberately out of focus and be
used in a variety of genres (Wildlife / Sport / Macro / Portraits) where
the photographer deliberately wants to separate the main subject from the
background - for this effect, larger apertures will be applied ie. f/1.4 - f/8 (see below image)



Lens Apertures f/2 - f/22

Aperture Demo: Canon EOS 6D / EF 85mm f/1.8 USM Lens f/1.8 - f/22  View 

Lens apertures
In DSLR photography different lenses are used to create / select different
levels of DOF depending on the lens aperture range, optical length of the lens
and distance from subject. Different lenses / aperture settings will be applied
for different type of photography genres requiring blur effects at various
focal lengths ie. for close-up / macro, portraiture or wildlife photography. a
DSLR camera system is not necessarily required for creating deliberate image
blur, a compact camera with a wide aperture lens with some optical zoom will
also work to some extent.

See Aperture / DOF Demonstration 
Aperture / DOF Demo

Aperture is used to control the exposure of a deep or a shallow Depth Of field
(DOF) for a specific composition. A smaller f/number allows more light into the
camera via the lens ie. f/2.8-f/5.6 and will create a shallow DOF for a close-up
subject against a background (isolating a flower from its surroundings). See article Digital Noise vs Blur

Shutter Speed
Introduction to the Exposure Triangle: ISO / Aperture / Shutter Speed
Image 3: Canon EOS 7D Mark II  : 1/3200s Manual Mode
Shutter speed is the length of time the camera's shutter is open (and
closing) allowing light onto the sensor for a given time period. Shutter speed is always measured in time. Measured in fractions of a second ie.1/125 seconds, but can extend past 30 seconds up to hours. Most digital cameras will have a default range from 1/4000 – 30 seconds. But can be faster up to 1/8000 depending on the DSLR model.

Slow shutter speed
Refer to the article ‘Long Exposures / Night Photography Setup & Tips
(Using Av mode) 
long exposure demo for specific
examples to learn more about specific shutter speeds.

Fast shutter speed
To freeze motion photographers use fast shutter speeds to ie freeze the wings
of a bird in motion. See Image 3 
for the example
in which I captured the Bird In Flight (Image 3) at a shutter speed of 1/3200 seconds using Manual Mode: f/6.3  ISO 500 (Auto- ISO).

Suggested Shutter Speeds

To Capture Motion
  • Moving water / waterfalls 4+ seconds
  • Fireworks 4+ seconds
  • Moving car at night 8+ seconds
  • Night photography 1+ seconds

To Freeze Action
  • Birds in flight 1/1000+
    seconds
  • Moving water / waterfalls
    1/1000+ seconds
  • Cars / motorcycles 1/1000 seconds
  • Sporting event 1/500 –
    1/2000 seconds

Conclusion
The ‘Exposure Triangle’ settings will be available before every photograph is captured. For the new photographer Auto-mode and / or semi-auto modes such as P / Av / Tv modes will provide assistance in getting the best exposure for a given shooting environment.

New photographers should be in no rush to ‘have to’ understand all exposure settings and shootings modes as soon as possible. Learning about them is important, but more important is getting comfortable with your camera, menu settings and your compositions.

Photography is a visually inspiring journey that if allowed, will not just develop camera / photographic skills or exploring different environments, but contribute to an overall mindfulness and satisfaction of great image capturing (and sharing).

Taken literally, the Greek words photos and graphos together mean “light drawing”. Even today the term photography is being manipulated to fit digital imaging, but in its most elegant form, a photograph may best be described as a reasonably stable image made by the effect of light on a chemical substance. Light is energy in the form of the visible spectrum. If light or some other invisible wavelength of energy is not used to make the final picture by chemical means, it cannot, by this definition, be a photograph.
