ISO levels and noise on overcast day

just wondering what ISO levels are common for verry overcast days. I just go my first DSLR yesterday (black friday sale :)

Yeah dude 1250 is way too much, just don't use 1/500th of a second shutter speed. At f/10 on overcast you'd probably just need like 1/30th of a second at 100 ISO or 1/60th of a second at 200 ISO.

1250 ISO is overkill for the middle of the day.

I had no idea what iso to use so i just adjusted my aperture and shutter to go with 1000 XD But after looking at the photos I knew I goofed. Thanks for the tip :)

>>2972620
Don't listen to this faggot. You're shooting at 135mm on a crop body.
That's an equivalent of 216mm on canon crop. Generally you want your shutter speed to be higher than your focal length. So 1/250 would be fine without IS. Don't also default to lower ISO because plebs like the one who answered you replied to your post. To eliminate motion blur and reach optimal sharpness you want to keep the reciprocal shutter speed rule in mind when shooting photos. Picture the depth of field you want and set your aperture, freeze the motion by setting your shutter speed and think about ISO later.

I'd recommend reading up on the exposure triangle first and learning to achieve the effect you want first. It sounds like work, but it works. Ansel Adams has a neato series of books on camera operation which have timeless information inside, there are also a tonne of e-resources out there.

>don't default to lower ISO
They're shooting at 1250 ISO and making threads complaining about the resulting noise, lowering the ISO is literally the only solution. 100 or 200 ISO might be too low at f/10 if you don't have steady arms, but it absolutely must go to a lower ISO to solve OP's problem.

DUUUUUUUUUUUR HUUUUUUUUUUUUUUURRRRRRRRRRRR IF I SHOOT AT F/64 THEN THEN EVERYTHING WILL BE IN FOCUS HAHAHAHA
Chances are that f10 wasn't needed, but I'm sure some turboautist is going to burst in with a pointsinfocus link or something.

>>2972651
Thanks. Reading up on it right now.

On a digital camera there's really only two apertures that matter: wide open (for max light/bokeh) and the lens' sweet spot for diffraction (probably f/8 to /11, just use 8 if you dint know)

Shoot in aperture mode and auto ISO with a "minimum shutter speed" determined by focal length. (Many cameras have a setting that calculates it for you)

Tried 200 today, still getting noise. I'll try 100 tomorrow.

There is no such thing as zero noise. Lower ISO settings just have less. But you'll always be able to see some when pixel peeping at 100%.

If you shoot raw - you should - you can tweak noise reduction to balance between noise and sharpness.

did you raise exposure in post? someone posted an article about how you really want to be adjusting gain when taking the picture because its happening before ad conversion?

just dont clip. try ettr next time and lower in post to taste

I wouldn't worry about that much noise, looks like ISO 400 on mine.
I usually go with ISO 3200 noise when reasonably filling the frame with the subject. If you want crystal clear images you have to spend the money for the fast tele primes, support, blinds and the inevitable lower resolution much higher pixel size FF body like a 1D X or D4, maybe D810

>>2974966
In addition the noise in >>2972616 is still make for a decent shot. Try to fill the frame more, get a 200mm or 300mm prime if you intend to do wildlife more often.
Maybe get a used Tamron 70-200 VC and a 1.4X TC.
Cheers.
