Gear, backups and redundancy

At a studio shoot, a failed camera means a pause while a replacement arrives. At a wedding, a failed camera during the vows means a missed moment that can never be recovered, and a lost memory card can mean a missed wedding. Event photographers therefore think about gear differently: not only which camera and lenses make the best images, but what happens when each item fails. This lesson covers choosing cameras and lenses for events, the logic of redundancy, memory cards and dual slots, batteries and power, flash gear, carrying systems, backing up files during and after the event, and insuring equipment. Exposure and lighting fundamentals are in PHOT-201 and PHOT-220; this lesson focuses on reliability.

Cameras for events

Event cameras need reliable autofocus in dim light, clean high-ISO performance, fast and quiet shutters, long battery life and, ideally, two memory card slots. Mirrorless cameras now dominate event work because of eye-detection autofocus, silent electronic shutters for quiet ceremonies, and accurate exposure previews in the viewfinder; many photographers still use DSLRs successfully. Whatever the system, the essential rule is that a professional event photographer carries at least two camera bodies that can each do the whole job. Two bodies also allow two lenses to be ready at once, such as a wide zoom on one and a telephoto on the other, which reduces lens changes during fast-moving moments.

Electronic shutters allow silent shooting during vows, speeches and performances, but they can produce banding under some artificial lights and distortion with fast movement, as covered in PHOT-220. Test silent mode in similar lighting before relying on it.

Lenses for events

Most event photographers rely on a small set of lenses:

• A standard zoom, such as 24-70 mm f/2.8 on full frame, for getting ready, groups and general coverage.
• A telephoto zoom, such as 70-200 mm f/2.8, for ceremonies from the back or side, candid reactions, speeches and portraits with compressed backgrounds.
• Fast primes, such as 35 mm, 50 mm or 85 mm at f/1.4 to f/1.8, for low light, shallow depth of field and lighter carrying.
• A wide lens, such as 16-35 mm, for venues, dance floors and large groups in tight spaces.
• A macro lens, such as 90 to 105 mm, for rings and details, often doubling as a portrait lens.

The f/2.8 zooms are heavy but versatile; primes are lighter and brighter but require moving or changing lenses. Many photographers carry two zooms and two primes, and choose lenses for each part of the day based on the space and light they found when scouting.

The logic of redundancy

Redundancy means having a second way to do every critical job. For each item in the kit, ask: if this fails in the middle of the ceremony, what do I use instead, and how quickly? Critical items include camera bodies, a lens for each focal-length range, flash units, memory cards, batteries and chargers. Less obvious ones include the cable or card reader used to back up files, the car that carries the gear, and the photographer: a contract should say what happens if the photographer is ill, and many photographers have an agreement with trusted colleagues to cover each other in emergencies.

Memory cards and dual slots

Memory cards fail rarely, but event photographers shoot thousands of frames a year, so rare failures still happen. Cameras with two card slots can write every image to both cards at once, called backup or mirror mode, so a single card failure loses nothing. This is the strongest single protection against loss during the event. Other good practices include:

• Use reputable cards from trusted suppliers, because counterfeit cards are common online.
• Format cards in the camera before each event, after confirming the previous event's files are backed up.
• Use several medium-capacity cards rather than one huge card, so a single failure or loss affects fewer images, and change cards at natural breaks.
• Store used cards in a labelled case on your person, never loose in a pocket or bag.
• Replace cards on a schedule and after any error message.

Batteries and power

Mirrorless cameras use more battery power than DSLRs, and cold weather reduces battery capacity, as discussed in PHOT-330. Plan for at least three batteries per body for a full wedding, charged and labelled, plus chargers and a power bank or car charger for long days. Flashes use AA batteries or proprietary lithium-ion packs; bring enough to replace every set at least once. Rotate batteries in a consistent order, keep spent batteries separate from charged ones (for example, by turning the cover over), and charge everything the night before.

Flash and lighting gear

Lesson 7 covers flash technique. For reliability, carry at least two speedlights and preferably three, with wireless triggers and spares. Many photographers use one flash on camera for bounce and two off-camera flashes on light stands for receptions. Bring light stands, a small softbox or umbrella, gels for matching ambient light, and a small LED light for video-style fill or focusing assistance. Check that triggers and flashes share the same radio system and firmware.

Carrying systems and kit organization

Event photographers move constantly, so the way gear is carried affects both speed and health. Options include dual-camera harnesses or belt systems that hold two bodies at the hips, sling straps, belt pouches for lenses and batteries, and a rolling case or backpack left in a safe place as a base. Keep the base kit in sight or in a locked room, because theft at public venues does happen. A consistent layout, where every item always goes in the same pocket, makes it possible to change lenses or cards quickly in the dark without thinking.

Backup after the event

The event is not over until the files are safe. A common rule is 3-2-1: three copies of the data, on two different types of storage, with one copy off site. In practice:

• Back up cards to a laptop or portable drive the same evening, and keep the cards unformatted until at least two other copies exist.
• Copy to a second drive kept in a different place, and to a cloud backup service.
• Verify copies, for example by checking file counts or using software that verifies checksums.
• When travelling, keep one copy with you and another in a separate bag, so a single theft does not take everything.

Lesson 11 covers longer-term archiving and retention.

Maintenance and checks

A gear checklist before every event catches problems early: sensor and lens cleaning, firmware updates (installed and tested well before an event, not the night before), card formatting, battery charging, flash testing, and a test shoot to confirm that both slots are recording. After each event, check gear for damage, clean it and note any problems. Keep a written log of equipment purchases, serial numbers and repairs, which helps with insurance claims and resale.

Insuring equipment and liability

Professional photographers usually carry two kinds of insurance, as introduced in PHOT-302. Equipment insurance covers loss, theft and damage to gear, including at events and in vehicles; standard home insurance often excludes business equipment. Commercial general liability insurance covers injuries to others or damage to property caused by the photographer's business activities, such as a guest tripping over a light stand; many venues require proof of liability coverage, often a certificate naming the venue as an additional insured, before allowing a photographer to work. Some photographers also carry professional liability (errors and omissions) insurance for claims that they failed to deliver the promised service.

Travel and destination events

Destination weddings and out-of-town corporate events add risks to gear: airline baggage handling, theft from vehicles, customs inspections, humidity and extreme temperatures. Carry cameras, lenses and memory cards in cabin baggage, check airline rules on lithium batteries, which generally must travel in the cabin with terminals protected, and keep a list of serial numbers for customs and insurance. Confirm that equipment insurance covers travel outside the country.
