In the past few weeks, we’ve mastered both aperture and shutter speed in relation to winter photography. This week we’re taking a quick look at the final pillar of photography: ISO.

ISO is the last step to understanding the basics of shooting on manual mode and is a crucial component to a well-exposed photo.

What is it?

ISO is your camera’s sensitivity to light. Back when film photography ruled the land, ISO was an indication of how sensitive the roll of film was to light. Now that digital photography is king, ISO still functions the same but now refers to the sensitivity of the image sensor, not the film. When shooting on film, photographers were stuck with whatever ISO the film was set to but with digital photography, photographers have the freedom to change the ISO for every shot.

How is it measured?

ISO is measured in numbers. The higher the number, the more sensitive your sensor becomes to light. The lowest ISO setting on a camera is 100 and from there, the sensitive doubles in number as the ISO increases 200, 400, 800, 1600, 3200, 6400, etc. High ISO is used in very low light conditions and low ISO is used in bright conditions.

ISO Scale

Why is it important?

Often when you adjust your aperture and shutter speed settings, you’re left with a dark image. This is especially common when a fast shutter speed or a small aperture is required. 

In those instances, you may need to bump up your ISO to compensate for the lack of light. For example, if you’re shooting a low light action shot, such as a snowboarder at dusk, you’ll want to maintain a fast shutter speed to freeze motion which might require a high ISO to maintain the light. On occasion, even if your aperture is wide and your shutter speed is long (when shooting the stars, for example) you’ll still need to have a high ISO to get enough light onto the sensor.

What’s the drawback?

With photography, changing a setting always has a counter effect and with a higher ISO, the drawback is the amount of grain (or noise) in a photo. The higher the ISO, the grainier the photo.

ISO 100 should be where you start as this will give you the sharpest and cleanest shot possible (with almost no noise/grain), however, you may find yourself in a situation where you need to increase your ISO due to lack of light.

You do not need to be afraid of bumping up your ISO as the technology of digital cameras have come a long way and are able to handle high ISO settings.

Having said that, just because your camera can go to ISO 6400 doesn´t mean you should.

We recommend shooting the same image with different ISO settings, then compare those shots to see how high you can put your ISO before it ruins your image.

How does it work with Aperture and Shutter Speed?

ISO is a key part of the exposure triangle and adjusting the ISO settings will have a direct effect on the aperture and shutter speed. Bumping up your ISO to 400, for example, will make the exposure brighter, allowing you to increase the shutter speed or have a smaller aperture (both of which decrease how bright the exposure will be). Of course, increasing the ISO will also increase the graininess of the photo so start at ISO 100, set your aperture and shutter speed first, then adjust your ISO to a higher setting as the last resort.

ISO Settings for Winter

Our Winter ISO Setting Recommendations:

Its hard to give you an exact ISO setting as this very much depends on your other settings and the available light, however here are some good starting points:

Bright snowy landscape: ISO 100

Winter sports during the middle of the day: ISO 100

Winter sports photography in low light: ISO 800

Cloudy winter day: ISO 200-400

Northern Lights: ISO 1600

Winter night sky: ISO 800-3200

    Please note, our gloves are designed to fit snuggly to give you the best camera feel without compromising on warmth. If you prefer a looser fit, please size up.

    As we learn more and more about gloves we also learn that all hands are different. Some people have long skinny fingers and slim wrists, others have wide hands with short fingers.

    Our gloves wont fit all even with the right measurements from the sizing chart – but we try!

    What size should I get if I'm between sizes?

    For many, the best option will be to go up a size if your measurements are in between sizes.

    If you are between sizes or if your hands do not fit into the measurements on our sizing chart, we recommend prioritizing the fit for the girth measurement. The girth is the most important measurement and if you the girth size on the glove is too small, you won't be able to fit the glove.

    Should I size up for my liner glove?

    If you’re considering pairing a liner glove with your photography gloves, we recommend choosing the same size liner as photography glove. We designed our liners to be thin and fit inside of our photography gloves so we recommend your normal size in liners. There are two exceptions to this:

    Exception #1: If you are at the very end of the ratio size in the sizing chart, e.g. 1 mm from being a size Large, then we advise going up a glove size if you plan to often wear the liner with the gloves. 

    Exception #2: If your personal preference is to wear fairly loose gloves, then you should also go up a size when adding a liner. We don't recommend this as you will compromise dexterity with loose gloves and our priority is best possible camera feel. But you know best what you like!

    House tip: Make sure to chose a liner size that is snug/tight on your hand for the best Fliptech performance when wearing liners and gloves together.
