As I mentioned, earlier, the “Auto” mode in a camera, makes use of this Triangle to shoot the optimum photo. In simple words, the cameras “Brain” (CPU) uses the best algorithm (derived from this triangle) to produce the best result.
To sum up, let us consider the “3 Corners” of the triangle, with its Advantages & Disadvantages.
- Narrow Aperture (Eg: f 22) opening & longer Shutter Speed (Eg: 1 Sec)
Advantages:
- More Depth of field
- More natural light allowed into the image sensor
- Slow shutter speeds allow low light photography
- Faster, Auto focusing
- Less strain for Manual Focusing,
- Overall performance of the LENS will be better (Less aberrations)
Disadvantages:
- More chances of shaky Photos, because of long duration of light allowed in to the sensor.
- Low light will also call for higher ISO, making the photos grainier.
Fast Shutter speed & higher ISO
Advantages:
- Faster shutter speed makes less shaky pictures.
- Higher ISO (To me, within, one tenth of the maximum available value, in your DSLR camera or ¼ in Mobiles) allows better low light photography.
Disadvantages:
- This situation, also may call for larger Aperture, making the Lens aberrations more clear. (Eg; Close-ups will look ugly)
- Colour clarity may reduce
- Larger Aperture & Lower ISO
Advantages:
- Lower ISO allows better flexibility for post processing
- Also, on zooming, better clarity
- Larger Aperture allows more light, enabling better low light photography
Disadvantages:
- Larger aperture brings, a lot of clarity problems in lens
- Lower ISO, may call for Slower shutter speed, making the photos more shaky.
This topic was really, more theoretical (dry) than, practical; but, to my knowledge, if not today, tomorrow you will need these data, desperately.
Thanks, All
