How To Disinfect Camera Equipment And Working Space, Told By A Physician

Disinfect Camera

Here are some tips about how to disinfect camera and lenses. Did you know that Roger Cicala of Lens Rentals was a physician? I did not.

So, instead of tearing down lenses, this time Roger Cicala gives some valuable and professional advice about how to disinfect camera gear and the space where you are working.

We feature only a small excerpt of the instructions and invite you to head over to Lens Rentals to learn the best practices to disinfect and properly clean cameras, lenses, and your working space.

Alcohol  and Soap

Despite what some manufacturers have said, we, and every repair shop I know have used isopropyl alcohol in 60% or greater concentrations on camera equipment for a long time and haven’t seen any adverse effects. Some manufacturers said 99% isopropyl might maybe affect lens coatings. I respectfully disagree, although I will say vigorous rubbing can affect some lens coatings, so take it easy and don’t use wire brushes or such.

Don’t soak it; that is asking for trouble and isn’t necessary. Just moisten it. Use common sense to try to keep your disinfectant on the outside and not let it run into the inside. A light mist with a spray bottle, or a cloth or paper towel dipped in alcohol works great for large surfaces. You might want to dip a Q tip or similar thing to get into small areas or places where you’d rather not spray.

How to Protect Your Camera in Cold Weather (Canon infographic)

Protect Your Camera

Going out to take pictures in cold weather? You better protect your gear. The infographic below tells you how to protect your camera

Before You Head Out 

1. Never leave the house without wearing a pair of waterproof and insulated boots to keep your feet warm and dry, even after standing for long hours. 

2. Go out with fresh batteries and carry spare ones in your pockets. This ensures you’ll be able to quickly switch to fresh, warm batteries and continue shooting. Also consider using an additional battery grip for longer lasting power.  

3. Bring along a carbon fibre tripod as it handles the cold better and helps to lighten your equipment load. If you’re using an aluminum tripod, wear your gloves when touching it. Find out the basic equipment you’ll need to bring with 10 Things to Pack for a Photoshoot

Here is the infographic about how to protect your camera:

Cold Weather Shooting Tips 

1. Clean and crisp winter air means sharper photos. With the sun lower in the sky, quality of light is better for more hours of the day. The shadows formed are also longer, which adds more interest to landscape shots.  

2. Snow can be tricky to shoot. Tip: Expose for the brightest portions of the scene and ensure your highlights don’t get blown to all white. Using a lens hood also keeps light from bouncing around.  

3. Use a circular polarising filter (CPL) to clear up any haze in your photos, and reduce glare on snow and ice.  

4. Limit your usage of the LCD screen to cut down on chimping, or checking every photo immediately after clicking the shutter button. Instead, use your camera’s viewfinder to help conserve battery life. 

5. Achieve a minimalist look in your images by keeping an eye out for details, such as a ski cabin that stands out on the mountainside, as the landscape becomes a blank canvas for you to get creative with.

How To Use Rule Of Odds and Rule Of Symmetry In Photography (Canon Infographic)

Rule Of Odds

After the infographic about the rule of thirds and the golden ratio, here is another short infographic by Canon’s Snapshot site.

This infographic is about the rule of odds and the rule of symmetry. From Wikipedia:

There are numerous approaches or “compositional techniques” to achieve a sense of unity within an artwork, depending on the goals of the artist. For example, a work of art is said to be aesthetically pleasing to the eye if the elements within the work are arranged in a balanced compositional way. However, there are artists […] who aim to disrupt traditional composition and challenge the viewer to rethink balance and design elements within art works.

[…] The “rule of odds” suggests that an odd number of subjects in an image is more interesting than an even number. Thus if you have more than one subject in your picture, the suggestion is to choose an arrangement with at least three subjects. An even number of subjects produces symmetries in the image, which can appear less natural for a naturalistic, informal composition.

An image of a person surrounded/framed by two other persons, for instance, where the person in the center is the object of interest in that image/artwork, is more likely to be perceived as friendly and comforting by the viewer, than an image of a single person with no significant surroundings.

And without further ado, here is the infographic about the rule of odds and the rule of symmetry:
