Looks like this guy is making beginners more confused.

Comparing low vs high ISO as same shutter speed, then of course the low ISO picture will be darker. Then increase brightness digitally to show more noise and say lower ISO more noise. 

Try to shoot picture at correct exposure with low ISO and also with high ISO, meaning the low ISO one with longer exposure compare to the high ISO one. This will give both picture with same brightness. Then magnify the picture to see which one is grainier. I can bet the the one with high ISO will have more noise.

Your statement is only valid looking at one perspective. 

ISO tu quality standard ke

Anything for view count these days.

sensor nowadays so good, crank up iso je.

noisier image is better than blur image.

embrace the shadows, dont be afraid of the dark
a good photo not necessary must be bright and sharp

Never get these IsO thingy even with leica lens cam n hP

get a faster lens

Anything for view count these days. Obviously, you could use higher ISO, it just depends on situation. People who stick to 50-100 guideline just tend to stay safe and don't like to do much of tests or trial. But to say lower ISO produces noisy photo compared to higher ISO is just misleading.

yang master tu pandai use any kind of light source.

Faster lens just have the ability to shoot with shallower depth of field. It wont have the ability to produce better shots.

bigger aperture reduce depth of field la...

i would prefer m-mode

set the safe shutter speed according to the environment/movement
lens/sensor stabilization works for stationary

set the aperture size according to your intended depth of field

set the iso to auto, some ppl might put a capped on max iso
exposure indicator will blink if under or over exposed, that time baru re-adjust shutter speed and/or aperture size.

adjust exposure compensation when needed

Anyone still saying we must stick to ISO 100 or ISO 50?
Is that from a photography book/magazine published 20 years ago?

some situation darker shot is unavoidable. so

for example:

1. i need to freeze the motion of moving people (in my case i need at least 1/400s, but i ended with 1 stop faster 1/800s)
2. already max out the aperture (f1.8)
3. already max out the native iso (ISO 5000)

this was the sooc jpeg with 2.5-stop under exposure:


it's important to shoot raw so that can post-process later to make unusable photo to usable:

bare in mind that this photo was taken with small sensor camera Olympus E-PL5 that was introduced in 2012, so most camera that is newer than this and bigger sensor than this can produce better post-processed result.

i got Lumix LX3, i use auto jerrr, now that the batt is kong, and the screen cacated, my samsneg exynos flagship camera to capture the Moment > noiseless

This guy only tokok know little but big mouth.
Each camera behaved differently there are no single better way. At the end you have your own requirements and ai noise reduction work so well nowadays that iso hardly matter anymore.

For me I just stick with 100 because I always shoot more than 1 sec on a tripod anyway.

Dont care about iso if you shoot raw

You crank iso in camera or in lightroom same result

Then use lightroom raw denoise. Its almost magical
