The Triangle

Bonjour!

Okay let's start with the simple most basic thing you'll have to know.. it has 3 things, the ISO, Shutter and the Aperture.. all 3 combined, known as the ISO triangle.

ISO:
Well the ISO is pretty much the first thing you'll have to set up before doing anything else. it depends on the surroundings you're in at the current moment. Some of the high-ends DSLRs have an  ISO up to 64000 perhaps more, but with a noise-reduction tech so you won't be able to worry about the Noise popping out of your picture later. Conclusion, well the lower the ISO, the less sensitive the sensor is to light. meaning it'll be darker.. but it also depends on the Shutter speed.

Oh and the Noise, take a look at the sample up here. 2 same pictures, with a different ISO rating. the one on the left has an ISO of 3200, while on the right has 200. that is a huge difference there right? And not a pretty sight there on the left. My advice, never take a picture with the ISO above 400. NEVER, unless your DSLR is expensive then fine..


Next up is Aperture:
Aperture is the size of the shutter itself, the reading is usually f/2.8 or f/4 and so on.. This part relies heavily on the lens you're using.. but for now im just starting with the basic starter kit lens. the 18-55mm NIKKOR lens. This is where bokeh is the priority. Take a look here :

The lens we're talking about is only f/4 to f/5.6, still it is enough for bokeh.. albeit trickier without a lens of sort... IF you set the Aperture to f/4 or lower, then your DoF is more shallow, allowing you to take picture easily since the light entering lens and reaching the sensor is more, then if you set to an aperture of f/22.. if you did that, you're gonna have a bad time taking pictures since it's so small.. Look at your LCD screen when setting it, you'll see. In my opinion just leave the Aperture as wide as possible

Now comes the fun part
Shutter Speed:
I would always mess around with the Shutter on subjects such as the rivers, the cars travelling by across the road at night and so on..This is basically the last thing you ought to set up.. from ISO to Aperture than to Shutter. For this sub-topic shutter speed has the potential capability of producing motion blur. This depends on the light intensity and the ISO and a little of your Aperture settings.. I know it sounds complicated at first, but soon you'll realize it's an easy task.

Now this is a picture I stole from the internet... by stealing I meant borrowing hahaha...
Take this as an example of a low Shutter Speed. this style, you can't use it with your hands only.. Either support yourself using a railing(pretty much suicide) or use a Trpod to steady the picture. Im sure you get the idea of the tripod being used, due to the motion blur with a low Shutter setting

Now take this as an example of a high shutter speed setting xD
No he didn't kick him in the groin, he merely thrusted his foot up, while the victim jumped up, so no accidents that time.Take note that if you set the shutter above 100 then you'll be fine under daylight, and lower shutter speed for darker areas, or night time, to allow light to enter the lens.. Recommend to the photography as daylight, unless there's a specific place at night where the city neon lights thrive such as I-City.

That's all for now TTFN, tata for now
