Each year, we would expect our Indonesia neighbor to create some haze from their plantation burning exercise throughout the land for a couple of months, all while messing up the air of the island from July to September.
And it would be wise to tone down our shooting spree down a bit during this period, so as not to turn our lungs into the haze's air filters. So, its also a good time to consider a higher ground approach to continue shooting. One such possibility is to drive up to Malaysia highlands, where these haze seems unable to pollute.
Cameron highland is one such place I frequent during the haze seasons. And could well be the place I will escape too in July for a week at least.
