Welcome to our in-depth guide on underwater photography, where we will plunge into the fascinating world beneath the waves. Capturing the beauty of aquatic life and submerged landscapes requires skill, specialised equipment, and a deep understanding of the underwater environment.

Whether you’re an experienced photographer or a beginner, this guide will equip you with the knowledge and techniques needed to take breathtaking underwater photos.

The Essentials of Underwater Photography

Underwater photography presents unique challenges, including water clarity, light diffusion, and buoyancy control. Understanding these factors is crucial for successful underwater shots.

Investing in the right equipment is key to capturing stunning underwater images. We’ll discuss essential gear such as underwater housings, cameras, lenses, and lighting systems.

Mastering Light and Colour

Light behaves differently underwater, affecting the colours and clarity of your photos. In this section, we’ll delve into techniques for managing light and enhancing colour.

Learn how to use underwater strobes and video lights effectively to illuminate your subjects and counteract the loss of colour in underwater photography.

Step-by-Step: How to Colour Correct an Underwater Photo

Colour correcting a photo taken underwater is crucial to bring out the natural and vibrant colours that may be lost due to water’s filtering effects on light. Underwater environments can introduce a blue or green colour cast to your images, making them appear washed out or monochromatic. Here’s a step-by-step guide on how to colour correct an underwater photo:

Shoot in RAW

Whenever possible, shoot your underwater photos in RAW format. RAW files retain more image data, allowing for more extensive adjustments during the colour correction process compared to JPEGs.

Use a Dedicated Underwater White Balance Setting

Many underwater cameras offer specific white balance presets for underwater shooting. These presets are designed to counteract the colour shifts caused by water. Select the appropriate preset for your dive conditions, such as “Tropical Water” or “Blue Water,” if available.

Start with Basic Adjustments

First, adjust the exposure to ensure that your photo is properly exposed. You can adjust the exposure using tools like exposure compensation in your camera or software like Adobe Lightroom.

Increase contrast and clarity to make your image pop. This will help to define the details and enhance the overall visual appeal.

Correct the Colour Cast

Now, let’s focus on correcting the colour cast introduced by the underwater environment.

Use the white balance tool in your photo editing software to remove the predominant colour cast. Click on an area in the image that should be neutral in colour, such as a white or grey surface. The software will adjust the colour temperature and tint accordingly.

Fine-tune the colours using the hue and saturation controls. Increase the saturation of blues and greens to restore the underwater colours. Be careful not to oversaturate, as it can lead to unrealistic-looking images.

Address Backscatter and Distortion

Underwater photos can suffer from backscatter (small particles or debris in the water) and distortion. To mitigate these issues:

Spot Healing or Clone Stamp: Use the spot healing brush or clone stamp tool to remove backscatter or other unwanted elements from the image carefully.

Lens Corrections: Apply lens corrections to reduce distortion and vignetting caused by the underwater housing. Many photo editing software programs have built-in lens profiles for popular underwater camera setups.

Once you’re satisfied with the colour correction and overall image adjustments, save your edited photo in the desired format (e.g., JPEG or TIFF). Be sure to keep the original RAW file intact for future editing if needed.

Remember that underwater photography may require some trial and error, as lighting conditions, water clarity, and depth can vary significantly. With practice and experimentation, you’ll develop a better understanding of how to effectively colour correct your underwater photos to bring out their full potential.

What to Look for in an Underwater Camera

Before diving into our list of top underwater cameras, it’s essential to understand the key features and considerations when choosing the right camera for your underwater adventures.

One of the most critical aspects of an underwater camera is its ability to withstand water pressure and moisture. Some cameras come with built-in waterproofing, while others require housing to protect them underwater.

Image quality is paramount in underwater photography. Look for cameras with high-resolution sensors, excellent low-light performance, and the ability to capture vibrant colours in challenging underwater conditions.

Consider the lens options available for the camera, as well as compatibility with underwater lenses and filters. Versatility in lens choices can significantly impact the range of subjects you can photograph.
