Some photos of Cultiveat from a photo assignment on sustainable farming. Got some lovely photos and learnt even more about the state of farming and agriculture here in Malaysia. There is so much we don't know about how the food we consume is grown and distributed. From excessive amounts of pesticides to shady business practices, the food we eat is unethical and unsustainable. But it feels good knowing that there are people like Cultiveat out there that are trying to make a change! Highly encourage you to check them out and read more about sustainable agriculture. The topic has been on my mind for the past few weeks already and I've learnt so much from just doing a couple of Google searches.

Shot on a Canon 1Dx Mark III and 5D Mark IV.
Lenses were the EF 16-35 F4, EF 35MM F1.4II and EF 70-200 F2.8III

一小時營火，拍攝於海拔2574m的福壽山農場, Relaxing Campfire with Crackling Fire Sounds

高山營火最大的差別就是....好冷，五度低溫有夠冷，營火不再是氣氛用，真的是取暖用，再來就是安靜，天冷的高山沒蟲鳴鳥叫，好安靜。

一樣是一小時的營火，適合失眠，睡覺前服用，有效果又不傷身體。

Got my hands on the brand new RF 70-200 F4 IS USM for a couple of days. I tried my best to bring it out on a couple of shoots (not many due to the lockdown) to test it out. This isn't a review because I believe reviews should come from long term use, but rather and in depth first look/impressions of this lens. I wanted to answer a few questions such as size, weight, bokeh and usability. After a few days of testing out the lens, I feel I have a good idea on what this lens is good at and where it fails. I also briefly compare it to the 2.8 version. Hope this video helps!

Thought I'd share some photos and tips from a photo documentary assignment I did at the end of last year. I personally enjoy understanding the thought process behind how other photographers interpret creative briefs and how they go about creating the images based on a situations presented to them. This shoot was one of a few shoots for a project I was on. Let me know if you like watching these kinds of videos. I'll also try to take actual BTS footage the next round!
