"It is my intention to present – through the medium of photography – intuitive observations of the natural world which may have meaning to the spectators." - Ansel Adams

Introduction

It is well-document throughout the Vernon Chalmers Photography website that more attention on visual intuition and human behaviour is asserted than any Canon camera / lens in my hands at any given time.

It took me more than ten years through existential motivation and onsite learning to anticipate birds in flight, flight movements at Woodbridge Island, Cape Town to understand their actions / reactions. During this time I made very little change to my Canon camera equipment, but spent long periods of time learning birds in flight behaviour and the various environmental variables / conditions in capturing many of the various bird species in action at Woodbridge Island. - Vernon Chalmers

Importance of Intuition 

"Vernon Chalmers emphasizes the importance of intuition in photography and life 1. He believes that trusting your intuition is crucial for capturing meaningful and spontaneous moments 1. Here are some of his thoughts on intuition:
  • Photography as Intuition: Vernon views the camera as a sketchbook and an instrument of intuition and spontaneity 2. He encourages photographers to trust their intuition and focus on the moment rather than striving for a perfect shot 1.

  • Human Perception: He believes that human perception and perspective through the viewfinder are more important than the science and technology in one's hands 1. This approach allows for a more authentic and emotionally resonant experience 1.

    Enjoy the Process: Vernon advises photographers to enjoy the special moments and work towards an ideal exposure rather than obsessing over technical perfection 1." (Source: Microsoft Copilot 2024)

Intuition in Photography

"Intuition in photography refers to the ability to instinctively recognize moments, compositions, or lighting conditions that will create impactful images without relying heavily on conscious analysis or predefined rules.

It’s often described as a "feeling" or "gut instinct" that guides photographers to make creative decisions in the moment. Intuition plays a vital role in various aspects of photography:

1. Capturing the Moment
  • Photographers with strong intuition can anticipate and capture decisive moments, such as fleeting expressions, spontaneous interactions, or transient natural light. This is particularly significant in genres like street photography, wildlife photography, and event photography.
2. Composition and Framing
  • Rather than meticulously planning every shot, intuitive photographers often "see" the composition before it’s fully formed in their viewfinder. They instinctively understand balance, leading lines, and the rule of thirds, sometimes breaking these rules for artistic impact.
3. Emotional Connection
  • Intuition helps photographers connect emotionally with their subjects, whether they’re people, landscapes, or still life. This connection often translates into images that evoke strong emotions in viewers.
4. Adapting to Conditions
  • Lighting, weather, or unexpected events may require quick adjustments. Intuition allows photographers to adapt creatively, choosing the right angles, settings, or techniques to make the most of changing circumstances.
5. Developing Intuition
  • Although it might seem innate, intuition in photography can be cultivated:Practice: The more you shoot, the more you develop a sense of what works.
    • Observation: Study the work of skilled photographers and analyze what resonates with you.
    • Experimentation: Trying different styles, settings, and subjects enhances your ability to "feel" your way into a shot.
    •  Mindfulness: Being present and fully engaged with your environment sharpens your ability to notice subtle details and opportunities.
    • Intuition and Technology
      While modern technology like AI-driven autofocus and computational photography assists in technical aspects, intuitive photographers often use these tools to complement their        creative instincts rather than replace them.

Connection with Vernon Chalmers' Work

Since you’re interested in Vernon Chalmers existential motivation, it’s worth noting that intuition can play a significant role in aligning personal purpose with photographic expression. For Chalmers, intuition might manifest in his ability to connect with his subjects, be it the Cape Town landscapes or birdlife, capturing their essence in a way that resonates with meaning and his view of life."

Understanding Lens Minimum Focusing Distance (MFD)

Lens Minimum Focusing Distance (MFD) is an important consideration when longer focal length lenses (i.e. 300mm to 400mm) are used for close-up (butterflies and / or flower) photography.

Lens Minimum Focusing Distance : Canon Lenses

Updated: Understanding MFD of Canon Camera Lenses

Lens Minimum Focusing Distance (MFD) : Canon EF 50mm f/1.8 STM Lens
Lens Minimum Focusing Distance (MFD) : Canon EF 50mm f/1.8 STM Lens

What is Lens Minimum Focusing Distance (MFD)?
MFD is the minimum distance between a camera sensor and image / subject in front of the lens that will allow focus with a specific lens. Lens MFD is measured in meters (and displayed as such i.e. 0.98m or 3.5m).

MFD is an important factor for close-up photography when using zoom or non-zoom lenses (with / without lens extension tubes or lens close-up filters).

Most modern Canon EF and RF 300mm - 500mm (and other) telephoto / zoom lenses will have reasonable MFD's for capturing close-up subjects such as butterflies and flowers.

Canon Lens MFD Examples:

Helmeted Guineafowl at Kirstenbosch Garden

Helmeted Guineafowl at an MFD of 0.98m using the Canon EF 100-400mm f/4.5-5.6L IS II USM Lens at Kirstenbosch. As this image was in the shade I would certainly not achieved the same image quality / MFD with the Canon EF 100-400mm f/4.5-5.6L IS USM Lens.

Helmeted Guineafowl with MFD @ .98m : EF 100-400mm f/4.5-5.6L IS II USM Lens
Helmeted Guineafowl with MFD @ .98m : EF 100-400mm f/4.5-5.6L IS II USM Lens

Higher quality lenses will allow substantial cropping for creating expectable to reasonably high-quality close-up images of butterflies and flowers. Being a few meters away in creating a close-up image of a butterfly or a flower should still yield an acceptable result.

The specific Canon EOS / EOS R Full Frame or APS-C camera body used (ito image sensor, megapixels, etc.) could also have an impact on cropping (and additional post-processing) quality of the image.

Macro and Close-Up Photography Training Cape Town

For the attached butterfly images (at Woodbridge Island) I used the Canon EF 400mm f/5.6L USM lens while photographing birds in flight.

For most of my Kirstenbosch butterfly and flower images I use the Canon EF 100-400mm f/4.5-5.6L IS USM (Mark I) lens.

Understanding Lens Minimum Focusing Distance

"The minimum focusing distance of a lens refers to the closest distance at which a lens can focus and still form a sharp image on the camera sensor or film. It's the minimum distance between the subject being photographed and the camera sensor when the subject is in focus. This distance varies depending on the lens and its focal length.

Several factors contribute to the Minimum Focusing Distance:

1. Lens Design: Different lenses have varying construction and capabilities. Macro lenses, for example, are designed to focus at much closer distances compared to standard lenses. This is because they are optimized for close-up photography.

2. Focal Length: In general, lenses with longer focal lengths tend to have a longer minimum focusing distance. Telephoto lenses, due to their longer focal lengths, often have longer minimum focusing distances compared to wide-angle or standard lenses.

3. Internal Mechanism: The internal structure and mechanisms of the lens play a significant role. Some lenses have a floating element design or internal focusing mechanisms that allow them to focus at very close distances.

4. Camera System: The minimum focusing distance is also influenced by the camera system itself. The distance between the lens mount and the sensor or film in the camera body can affect the lens's ability to focus at close distances.

When a lens reaches its minimum focusing distance, it may not be able to focus on subjects closer than that distance, resulting in blurry images or difficulty achieving focus. This limitation is especially relevant in scenarios where photographers want to capture very small subjects or details at extremely close range.

Some lenses, particularly macro lenses, are specifically designed to excel at focusing on subjects at very close distances, making them suitable for capturing small objects with great detail, such as insects, flowers, or other intricate subjects.

Understanding a lens's minimum focusing distance is crucial for photographers, especially for those interested in macro or close-up photography. It allows them to determine the closest distance from which they can capture sharp and detailed images using their specific lenses." (Source: ChatGPT 2023)

Flowers. Every flower goes through stages of budding, opening, closing and wilting. Each of them has a preferred season and environment. They are unique. Like us. Each of us is unique. And like flowers, we each have a preferred season. So why do we expect ourselves to be in bloom all year round?” ― Rebecca Ryder

"The African Daisy, scientifically known as Osteospermum, is a vibrant and colorful flower native to South Africa. It is well-known for its daisy-like appearance, often featuring a central disc surrounded by colorful petals. The petals come in various shades, including purple, pink, white, orange, and yellow, sometimes with contrasting dark centers.

African Daisies thrive in sunny environments and are commonly grown as ornamental plants in gardens or containers. They are part of the Asteraceae family, which also includes sunflowers and chrysanthemums. These flowers are relatively easy to care for, requiring well-drained soil and regular watering, but they also appreciate a bit of drought once established. They're popular for their resilience, attracting pollinators like bees and butterflies." (Source: ChatGPT 2025)

Flower / Small Bird Photography with Canon EOS 6D Mark II
Kirstenbosch Garden provided me with another opportunity for experimenting with the Canon EOS 6D Mark II paired with the Canon EF 100-400mm f/4.5-5.6L IS USM lens - to be used as my main pairing when visiting Kirstenbosch Garden (across al seasons). We arrived a bit late with the light on the the over-exposed side on the whiter flowers / subjects.

I am quite confident that the Canon EOS 6D Mark II is more than just a subtle full=frame megapixel upgrade on the beloved Canon EOS 6D Mark I have used for close-up, harden and other photography for the past decade. Lens of choice for Kirstenbosch Garden: still the Canon EF 100-400mm f/4.5-5.6L IS USM Lens for a variety of small subjects.
