The Nikon D3400 has an ISO range of 100 through 25,600. An ISO of 100 means that the sensor’s light sensitivity is low. That’s a good setting for shooting in bright conditions. An ISO of 25,600 means that the sensor is very sensitive to even small amounts of light, making it a good option for night or low-light shooting.
Unfortunately, though, there’s a catch: the higher the ISO, the more you can get image noise (graininess) and poorer color rendition, both of which can impact the image quality in unpleasant ways. At ISO 100, the images should be the cleanest and have no noise, but as you get up to high ISOs of, say ISO 3200 and above, it’s something that can start to impact the image quality. In general, I’ve found the D3400’s images to be very usable up to at least ISO 3200, so it’s really only once you get above that that it might start to become an issue for many users.
How Do You Change the ISO on a Nikon D3400?
If you’re familiar with older cameras, you might be used to adjusting the ISO manually. You can certainly do that on the D3400, and it’s straightforward to do.
The main reason this question comes up is that there’s no button marked ISO on the body of the D3400. Other models do have such a button, but with the D3400 you have to go into the menu.
Just go into the settings menu on the back and choose the camera icon from the column at left. Then scroll down to ISO Sensitivity Settings.
Use the top line of the next screen (the item is called ISO Sensitivity) to specify what ISO setting you’d like to lock it on.
Use the right part of the circle button to drill down through the menu options, and hit the OK button to select.
How to Set and Use Auto ISO on the D3400
That manual setting works well, but there’s also another way to do it that, in many cases, is going to be better option. One of the features of modern digital cameras that has become indispensable to me is Auto ISO. It frees up the camera to change the ISO without messing with the other two sides of the exposure triangle: shutter speed and aperture.
To turn Auto ISO on, go to the small camera icon from the left column and scroll down to the ISO Sensitivity Settings item.
Then go down to the Auto ISO Sensitivity Control item and press right.
Maximum sensitivity. There are two further ways you can refine the setting. The first is specifying the maximum sensitivity. This imposes an upper ceiling on how high the ISO can go automatically (you can override it manually). If you want to use the full range of the camera’s ISO capabilities, you’d set this to 25,600. If you’re worried about noise impacting the clarity and image quality, you might set this lower. There might be instances where minimizing image noise is critical, so you might set it to, say, 800. But the Nikon D3400 has remarkably little noise up to at least 3200, so if you’re looking for a place to start, that probably makes as good as any.
Minimum shutter speed. The other related setting you can specify is the minimum shutter speed. Basically, it sets a minimum shutter speed that it will go to before Auto ISO kicks in.
You use this to reduce the risk of camera shake when you’re shooting hand-held. If the shutter speed is too slow when you’re shooting by hand (as opposed to using a tripod), you risk getting camera shake that makes the image blurry. There’s no magic answer as to what is too slow. Different photographers can naturally hold the camera more still than others, and if you’re shooting in cold or breezy conditions or some other kind of movement then it’s even harder to hold the camera perfectly still. So even if you can get tack-sharp photos at 1/30 in some conditions, you might need to crank that up to 1/125 if you’re shooting with cold hands.
Another variable is the focal length of the lens you’re using. Camera shake is a more immediate problem when you’re using a telephoto lens because even the smallest movement becomes magnified. It becomes less of an issue with wide-angle lenses.
The Minimum Shutter Speed setting can factor in the focal length of the lens when you use the Auto setting–that’s the one I’d recommend starting with. It uses the tried and true formula of matching the speed to the focal length along the lines of if your focal length is, say, 100mm, then at least 1/100 is a good target shutter speed. It’s not foolproof every time–as I said, there are a bunch of different factors that can come into play with camera shake–but it’s a good rule of thumb.
In the Auto mode, if you’re using a zoom lens the D3400 is smart enough to adjust this minimum shutter speed based on how much you’ve zoomed in or out. One thing it can’t do, though, is adjust it based on whether or not you have vibration reduction (VR) available and active.
Another common scenario might be if you’re shooting sports or wildlife. In this cases, you might want to specify a faster shutter speed to freeze the action. So you might want to set a minimum of, say, 1/400 or faster.
