If you are new in digital photography then there are a lot of things that you will learn by the passage of time in the field. However, there are some basics that you immediately need to know.
ISO, undoubtedly, is one of those basics.
You will need it for every image you are going to capture with a digital camera.
What is ISO in Photography?
Well, in short, ISO is a control of digital cameras that allows the photographers to get control over light internally. By controlling ISO, you can increase or decrease the brightness of an image without any help of external lights.
Sounds interesting? Trust me it is exciting from every aspect.
ISO is measured with numbers like 100, 500, 800, 1200, 1600 and many more.
The higher the ISO, the brighter the image will become. However, the amount of noise will also increase with higher ISO.
It is always ideal to keep the ISO at a lower scale.
Product photography and ISO
ISO usually does not vary in product photography much as most of the time it is facilitated with a set of sufficient amount of light when it is planned indoor. In case of outdoor product photo shoots, the organizers make plans keeping the light factor in mind.
To avoid noise in the product images, it is always preferable to keep the ISO at a lower scale.
Using ISO in Auto mode is mostly a wise decision, however, keeping it at a lower scale like 100 or 125 can keep your images noise free. And you will definitely get a crystal clear image with perfect light just by using your camera.
Along with all the benefits, you should also know that lower ISO will not work if you want to capture a clear image of something which is moving. For an example, if you are trying to frame a product like a fan and you want to capture it when the blades of the fan are moving, then it is not possible in lower ISO. The blades will have a ghost effect (blur mark) on the image.
A higher ISO will help you to capture the blades perfectly with a bit of noise.
