Digiscoping: A Fusion of Optics and Photography

Introduction

Digiscoping is a fascinating technique that marries the world of optics with photography. It allows you to capture stunning images using a spotting scope in conjunction with a digital camera or even a mobile phone. Whether you’re a birder, a wildlife enthusiast, or simply someone who appreciates the beauty of distant subjects, digiscoping opens up a whole new realm of creative possibilities.

What Is Digiscoping?

In simple terms, digiscoping involves taking photographs through a spotting scope. Here’s how it works:

  1. Spotting Scope: A spotting scope is a compact, portable optical instrument primarily used for observing distant objects. It’s commonly used by birdwatchers, nature photographers, and outdoor enthusiasts.
  2. Camera Integration: With digiscoping, you attach your digital camera (or smartphone) to the spotting scope using a specially designed adapter. This setup allows you to capture high-magnification images of subjects that would otherwise be too far away for traditional photography.

Advantages of Digiscoping

  1. Lightweight: Spotting scopes are significantly lighter than large camera lenses. They’re easy to carry, making them ideal for outdoor adventures.
  2. Magnification: Depending on your camera, eyepiece, and extenders, you can achieve magnifications of up to 4,000mm! Some scopes even allow for greater magnifications.
  3. Cost-Effective: If you already own a spotting scope, getting started with digiscoping is relatively straightforward. All you need is a phone adapter.

Disadvantages to Consider

  1. Cost: If you don’t already own a spotting scope, the initial investment can be a deterrent. However, there are excellent secondhand options available.
  2. Manual Focus: Digiscoping requires manual focusing through the scope. If you struggle with manual focus, this technique may not be suitable for you.
  3. Depth of Field: Due to long focal lengths, depth of field can be limited. Birds in flight can be challenging to track with a smaller field of view.
  4. Vignetting: Some eyepieces may cause vignetting. Adjust the zoom or crop the image in post-processing to address this issue.

Types of Digiscoping

  1. Phonescoping: Attach your mobile phone to the scope for convenient and acceptable results.
  2. Videoscoping: Capture movement and audio using your scope. High-quality screengrabs can be extracted from 4K footage.
  3. Digibinning: Attach a camera or phone to a pair of binoculars for an alternative approach.

Getting Started

  1. Scope Selection: Choose a quality spotting scope with good optics.
  2. Adapter: Invest in a compatible camera or phone adapter.
  3. Practice: Master manual focus and experiment with different settings.

Remember, digiscoping is about creativity and exploration. Start with the basics, observe the world through your scope, and capture moments that inspire you. Happy digiscoping!

Long Exposure Photography: A Guide to Capturing Time

Introduction

Long exposure photography, a technique that involves using a long-duration shutter speed, has the power to capture the essence of time in a single image. It’s a popular method among photographers who want to create dreamy landscapes, smooth water surfaces, light trails, and more. This blog post will guide you through the basics of long exposure photography and how to get started.

What is Long Exposure Photography?

Long exposure photography is a technique where the camera’s shutter is left open for a longer period of time, allowing more light to enter the sensor. This results in a photo that effectively captures the movement and passage of time.

Why Use Long Exposure?

Long exposure photography allows you to capture a different perspective of the world, one that our eyes can’t naturally see. It can turn bustling city streets into ghostly realms, make waterfalls look silky smooth, and create light trails from moving vehicles.

Equipment Needed

  1. Camera: Any camera with manual mode will work. You need to be able to control the shutter speed, aperture, and ISO.
  2. Tripod: Essential for keeping your camera steady during the long exposure.
  3. Neutral Density (ND) Filter: This acts like sunglasses for your camera, reducing the amount of light that enters the lens without affecting the color.
  4. Remote Shutter Release: This device can help you take a photo without physically touching the camera, reducing the risk of camera shake during the long exposure.

Apps to Assist You

  1. NiSi Filters Exposure Calculator (Android and iOS): This app helps you calculate the correct exposure time when using NiSi Neutral Density filters.
  2. Exposure Calculator (Android): This app calculates the equivalent exposure for a set of photos.
  3. Lee Filters – Stopper Exposure (Android and iOS): This app helps you calculate the exposure time for your photos when using Lee Filters range of Stopper long exposure camera filters.
  4. Camera FV-5 Lite (Android): This is a professional camera application for mobile devices, that puts DSLR-like manual controls in your fingertips.
  5. Easy Long Exposure Camera (Android): This app allows you to take long exposure photos and infinite exposure photos.
  6. Slow Shutter Fast Cam (Android): This app lets you capture long-exposure and time-exposure photos.
  7. Manual Camera DSLR (Lite) (Android): This app gives you DSLR-like manual controls for your camera.
  8. Long Exposure Camera (Android): This app allows you to take long exposure photos.

Steps to Take a Long Exposure Photo

  1. Set Up Your Camera: Mount your camera on the tripod to ensure stability.
  2. Compose Your Shot: Frame your shot just as you would with a normal photograph.
  3. Set Your Camera to Manual Mode: This gives you control over the shutter speed, aperture, and ISO.
  4. Adjust Your Settings: Start with a low ISO, set your desired aperture, and then adjust the shutter speed until you get a well-exposed image.
  5. Attach the ND Filter: This allows you to use a slower shutter speed without overexposing your image.
  6. Take the Shot: Use a remote shutter release or your camera’s self-timer to avoid any camera shake.

Conclusion

Long exposure photography might seem daunting at first, but with practice, you’ll be able to capture stunning images that truly stand out. So grab your gear, head out, and start experimenting with the flow of time!

Remember, the key to mastering long exposure photography, like any art, is patience and practice. Happy shooting!

Shooting the Moon

Created by ChatGPT – Release Notes (Feb 13)

Moon photography is a fascinating and challenging hobby that can yield stunning results. Whether you’re a seasoned photographer or just starting out, capturing the moon’s ethereal beauty can be a rewarding experience. In this post, we’ll explore some tips and techniques for taking great photos of the moon.

  1. Know the phases of the moon

The moon’s appearance changes dramatically as it moves through its phases, from the thin crescent of a new moon to the full and bright disk of a full moon. Understanding the moon’s phases and when they occur is crucial for planning your moon photography. Full moons are generally the best time to take photos, as they offer more light and detail than other phases.

  1. Use a long lens or telescope

To get a clear and detailed image of the moon, you’ll need a long lens or telescope. A telephoto lens with a focal length of 400mm or longer is ideal, and a telescope with a magnification of 200x or more will give you even more detail. If you don’t have a long lens or telescope, consider renting or borrowing one for the occasion.

  1. Use a tripod

To get sharp and steady shots of the moon, it’s important to use a sturdy tripod. Long exposures and high magnifications can amplify even the slightest movements, so using a tripod will help you get sharp and clear images.

  1. Choose the right time and location

The moon rises and sets just like the sun, and its position in the sky changes throughout the night. To get the best shots, choose a clear and dark location away from city lights, and plan to shoot at the moon’s highest point in the sky. This will typically be around moonrise or moonset, when the moon is low on the horizon and appears larger due to atmospheric distortion.

  1. Use manual focus

Most cameras have trouble focusing on the moon, so it’s best to switch to manual focus and adjust the focus ring until the moon is sharp and clear. You can use the live view function or a loupe to help with focusing.

  1. Experiment with different exposures

The moon is a bright subject, and getting the right exposure can be tricky. To start, set your camera to manual mode and try a few different exposures, from 1/125 second to several seconds. Experiment with different ISO settings, aperture, and shutter speeds to find the combination that works best for your setup.

  1. Post-processing

Finally, don’t be afraid to experiment with post-processing techniques to enhance your moon photos. Adjusting the brightness, contrast, and saturation can bring out details in the moon’s surface, and stacking multiple exposures can reduce noise and increase detail.

In conclusion, taking photos of the moon is a rewarding and challenging hobby that can yield beautiful and unique results. By following these tips and techniques, you’ll be well on your way to capturing stunning images of the moon. So grab your camera, find a clear night sky, and start shooting!
