When photographer Andri Tambunan is deliberating buying a new gadget, he first goes over a list of mental questions.

'€œIs it something I need or something I want?'€, he asks himself.

'€œSecondly, I look at the design and ergonomics. Does it look good and is it simple to use? Finally, I look at the price tag. If the price is high then I consider if it'€™s worth buying depending on how useful the gadget is in my daily life,'€ Andri said.

He admitted, however, that on some occasions, he disregarded those questions and simply bought gadgets based on impulse.

After receiving a Bachelor'€™s degree in photography from Sacramento State University in the US, Andri worked for a telecommunications firm in that country. After spending almost a decade in sales, he realized he wasn'€™t happy with his life.

After resigning from his position, he travelled the world for a year, during which time he witnessed a terrorist attack in Mumbai, India, on Nov 26, 2008. He was hanging out with his friends at a nearby bar when two terrorists opened fire inside Café Leopold in Colaba district, killing seven people.

'€œAfter they left I ran to the café; I had my little camera and I started taking pictures because I thought it was a crime scene and I wanted to preserve the evidence.'€

He ended up documenting the incident for many days. Upon returning to the states in 2009, Andri sold most of his possessions and decided to pursue photojournalism.

Based in Jakarta and Bali, Andri shares his time between commissioned assignments and self-initiated projects focusing on social, environmental and human rights issues.

An Apple user

For a tablet, I use an iPad 3 and for a hand phone, I still use iPhone 4s, though I am upgrading to the iPhone 6 soon.

I use a MacBook Pro laptop and a 120GB iPod classic. One laptop stays at home, which I use for scanning and uploading photos, and I take the other laptop with me when working on location. I use my iPod to listen to music and watch movies, which keeps me entertained during long flights.

I use Apple products because they are simple to use and synchronize with the rest of my gadgets.

Cameras for every occasion

When on assignment for clients I use a Canon 5D Mark II and Canon 6D and a Sony A7. These digital cameras have full frame sensors, full HD Video capability and they are light and compact (especially the Sony A7).

When I am shooting a personal project, I prefer to shoot with film cameras since there is no deadline and the quality is better than digital. I use a Mamiya 7, Mamiya 6, Bronica SQ-B and Voigtlander R3A.

Finally, for leisure, I use the camera on my iPhone and a Fujifilm Instax mini 90 Polaroid camera. I like shooting Polaroid because I can hold the physical pictures in my hand or I give them to my friends and family.

Apps for photography and social networking

For social media I use Facebook, Instagram, Tumblr and Twitter. To connect to my friends and family I use Facebook Messenger, Whatsapp, LINE, WeChat, Skype and Facetime.

For taking pictures I use the iPhone native camera, 645 Pro, Hipstamatic and Hyperlapse. I also use Snapseed to edit my photos, Light Meter to measure light, Pic Stitch to make a collage, LightTrac to evaluate the position of the sun and shadows at different times of the day when shooting outdoors and for my digital portfolio I use Foliobook.
