Mastering Manual Exposure

Mastering Manual Settings: My Journey to Learning Manual Exposure

Learning to use manual settings on your camera can seem daunting at first, but breaking it down into simple steps can make the process much easier. Here’s how I developed my understanding of manual exposure settings using a straightforward approach that worked for me.

1. Start with ISO and Aperture

To simplify things, I start by locking in two of the three exposure triangle settings: ISO and Aperture. This allows me to focus on one variable at a time without feeling overwhelmed.

• ISO: I set my ISO to a fixed value, typically 100 or 200, to minimize noise. (Easy to achieve in the light patterns I shoot in!)
• Aperture: Depending on the depth of field I wanted, I chose an aperture setting that matches my creative vision or the capabilities of my lens. This means I normally select the widest aperture for the lenses I have, typically f1.8 or f2 (Gather lots of beautiful light for fast shutter speeds and of course dreamy background!)

2. Focus on Shutter Speed

With ISO and Aperture locked in, I only have to think about Shutter Speed. My goal is to set a shutter speed that prevents camera shake or motion blur.

Here’s my rule of thumb: I set the shutter speed to at least twice the focal length of the lens I’m using. For example, if I’m shooting with a 50mm lens, I will set the shutter speed to 1/100s or faster. This simple formula helps ensure my images are sharp and free of unwanted blur.

3. Adjusting ISO for Proper Exposure

If I notice my shutter speed dropping below the minimum threshold needed for a sharp image, I will then adjust the ISO to a higher value. This increases the sensitivity to light allowing me to maintain the correct exposure without compromising the shutter speed.

For example:

• If my shutter speed drops to 1/60s and I need it to be at least 1/100th, I would increase the ISO from 200 to 400 or higher to compensate for the lost light.

4. Challenges and How to Overcome Them

Overexposure: In bright shooting conditions I’m simply shooting at a faster shutter speed as I’m at my lowest ISO. If I get to the maximum shutter speed then I will think about narrowing the aperture.

Low Light: In low-light situations, I will obviously look at shooting wide apertures to allow enough light into the camera. If I’m still not achieving the correct exposure I will continue to increase the ISO

Motion Blur: When shooting moving subjects, such as children or wildlife, achieving the right balance between shutter speed and aperture is key. I will prioritize a faster shutter speed, even if it means a slightly higher ISO.

5. Fine-Tuning My Technique

After getting comfortable with these basics, I begin to fine-tune my technique by experimenting with different settings and scenarios. I practice in various lighting conditions, from harsh midday sun to soft evening light, which helps me understand how each setting affects the final image.

• Indoor Settings: I practiced in low-light scenarios, adjusting ISO and shutter speed to achieve the desired exposure.
• Outdoor Shoots: I experimented with different apertures and shutter speeds to understand how they affect depth of field and motion capture.

6. My Takeaway

By focusing on one element of the exposure triangle at a time, I’ve simplified the learning process and have avoided feeling overwhelmed. This approach has not only helped me grasp manual settings but also made it fun and engaging. Now, adjusting manual settings feels like second nature, and I’m able to achieve the creative results I envision without relying on auto modes.

Whether you’re just starting out or looking to refine your skills, this method can be a great way to build your confidence in using manual settings. Happy shooting!
