Time is something precious. In the photography of a fast-moving world, you don’t have much time to react and capture the best moment. Technology has made it easier but it’s still not easy and likely never will be.
To put the odds of capturing a decisive moment in my favor,
I like to simplify my process so I can react quickly and get the shot. Nikon has helped speed things up with incredibly accurate auto modes, from exposure to white balance and fast frame rates. But there’s another unsung hero of auto modes that I’ve come to rely on and it’s Auto ISO.
With Auto ISO, even in manual mode becomes automatic because whichever aperture and shutter speed you set— ISO magically shoots up or down to give you the right exposure. Auto ISO will float to the magic number that makes your exposure as good as the amazingly accurate Matrix Metering system will allow.
The beauty of Auto ISO with Manual mode gives you both Aperture and Shutter Priority modes, letting you control the depth of field or selective focus while maintaining an image-sharpening fast shutter speed.
I began experimenting with the Auto ISO a few years ago and the benefits of this powerful feature were immediately obvious to me, and will be to you shortly
Auto ISO works in Aperture priority mode and in manual mode. I choose to use it in combo with manual mode to get the image look fully under control.
In aperture mode, you are allowed to set up the minimal shutter speed and Auto ISO will compensate to maintain correct exposure. It sounds easier to handle. You set only the aperture and camera does the rest. Did I just say “camera does”?
I love my camera and I do appreciate all the auto functions it offers me, but in all respect, I want to have the image look under control. Set the aperture for controlling the depth of field, set the shutter speed to freeze the action or has it low to capture the movement.
When using Auto ISO with manual mode? The beauty of this setup is that it’s so controllable and easy to use. If you using your head, you know what are you shooting and what to expect from aperture/shutter speed setting you don’t need to hassle with other setups what camera offer to you. Sounds amazing, does it. Well, to be honest, I found a few coins you need to know.
Even if you set the Auto ISO range from 100 to 3200, which are great 5EV range to compensate you will find sometimes it’s not enough.
You can underexposure or overexposure the image if you are not cautioned enough. But still, I found pretty easy to have an eye on exposure bar to check out if correction is needed.
Setup Auto ISO with manual mode
Set it up in your camera is quite an easy task. Since I have Nikon, I’ll give you the step by step for a typical Nikon camera, but it should be VERY similar for any brand.
- First, you’ll want to switch to Manual Mode.
- Next, you’ll want to turn on Auto ISO. For Nikon, this is found under the “Shooting” menu, “ISO Sensitivity Settings.”
- The first item is your standard ISO – this will act as your minimum ISO. I usually drop mine to the base ISO of the camera – for most Nikons and Canons this is usually ISO 100. The next item is “Auto ISO” – go ahead and switch that on. Once you do, you can dial in yourmaximum ISO. Go as high as you can tolerate (personally, I set 1600 for my D7200).
That’s it – don’t worry about the minimum shutter speed setting. For Nikon, that setting is ignored if you’re in Manual.
I hope I was successful in explanation of advantage what this setup can offer.If no, let me know, and I will try to do my best to help you.
