So how do you figure out exactly what the lowest possible ISO for your situation is?

This is why I repeat that the best ISO for landscape photography is the lowest possible for your given scenario. Sure, ISO100 or ISO64 are ideal as they don’t introduce much noise to the image but the truth is that there are many scenarios where you need a higher ISO. You see… There isn’t one correct ISO that should be used at all times. Since using a high ISO introduces a significant amount of noise to your image, you should always aim at using the lowest ISO possible. Read our Introduction to ISO in Digital Photography for more information Lower ISO is ideal… most of the time It works a lot faster, but with big losses of water, or a loss in quality if you prefer. With a higher ISO, the waterwheel will spin much faster but spilling a lot of water in the process. With this method, you will transfer all the water without any loss, but it takes more time. When ISO is low, the waterwheel will slowly spin without dropping any water. You can think of the ISO as a waterwheel. With a low ISO, you need more time to get the same amount of light to hit the sensor, meaning your shutter speed needs to be longer. This means that the higher ISO you use, the quicker the shutter speed you can use. The higher the ISO number, the more sensitive it is to light, while a lower ISO makes the camera less sensitive to light. More accurate it measures the sensitivity of the image sensor. Once you see a visible decrease in image quality, you need to start thinking more carefully.ISO expresses your camera’s sensitivity to light. ISO is often the first setting to get changed when you need to increase an exposure, and that’s fine-up to a point. Since noise is random, it’s unlikely that the same spots will show noise in every image. Astrophotographers regularly shoot multiple photos at ISO 6400 and then combine use them in post-production to offset the noise from the other images. The other option is to look at other ways of reducing noise.

On the other hand, if you’re going for a super clean look, then you’re probably out of luck.

I did a series of night portraits at high ISO values and, because I embraced the noisy look, I was able to shoot them at ISO 6400 without worrying too much. Where also depends on what you’re shooting.

As always, the exact value depends on your camera but, at some point, the images will become unusable, at least for professional contexts. Once you start to push past ISO 3200, you will see a dramatic increase in noise. Still, a good photo is better than no photo. In this range, you’re still going to get usable images, but they just won’t be the highest quality. You’re almost certainly shooting at night or working somewhere dark and, if you can’t reduce your shutter speed or widen your aperture any more, then upping the ISO is your only option. Increasing ISO to this point is a tradeoff. It’s not the highest you can push it, but it’s the highest you can go and reliably get good images. This range is kind of the highest you can push your camera in most situations without making a definite sacrifice in image quality. Again, it’s kind of camera-specific with lower end or older cameras, you’ll see it at lower ISOs than with higher end or newer cameras. Somewhere between ISO 800 and ISO 3200 range, you will start to see visible digital noise in your image even if you aren’t looking too closely for it. The best thing to do is play around with your camera and see how it operates at different values. I’m kind of arbitrarily calling ISO 800 the top of this range because it’s as high as most entry level crop sensor cameras can go without seeing some reduction in image quality, but on some newer and full-frame cameras, you’ll be able to push it higher. I regularly shoot portraits at ISO 400 so that I can guarantee my shutter speed won’t drop too low. If you need to use a faster shutter speed or narrower aperture than your base ISO will allow, you can confidently increase the ISO to around 800 without it having too much of an effect on the image. They’ve come along in leaps and bounds over the years, and the reality is, any modern camera can take incredible images between ISO 200 and ISO 800 with almost no discernible drop in image quality-or at least, not without you looking for one. ISO 200-800ĭigital cameras are incredible. The sample images for each ISO value below are cropped versions of the same image shot at the stated ISO value. Note: The image above was shot on a Canon 650D at ISO 100.
