Whether you think you can or you can't, you're right.

Automotive photography. Who does it? Who wishes they could do it? Rig shots, stills, composites: May I see your work in progress? Lets share ideas and techniques. Here's one of mine, before & after.

Dash Tip #2: Expanded ISO.
Hi 0.3 - Hi 2. ?

With the increase in processing power of todays DSLR cameras comes the capability to handle large amounts of high ISO generated Noise. When you crank up the ISO, you increase the sensors sensitivity to light (albeit, creating some grainy, but curable, noise in the picture).

However, what is EXPANDED ISO?!

Recall how an image looks when you zoom in on it with your mobile device, computer monitor, etc.

Terrible right? Looses quality as you zoom in.
Why is that?

Simply put: the zooming is just a magnification of the original image.

So naturally, the resolution is fixed and will degrade (in appearance) the more you magnify it.

This is opposed to REAL ZOOMING, which is accomplished by expensive glass, stacked in front of glass, in front of glass, to MAGNIFY a PHYSICAL SUBJECT so the cameras sensor can capture its details up close.

Now how does this concept apply to EXPANDED ISO?

ISO above 6400 generally is identified as EXPANDED ISO. It is no longer increasing the sensors light sensitivity and rather, artificially increasing the image brightness.

Thus, much more image degradation, grain, and possible color loss is expected when using ISO in that range.

OH NO! DOWN WITH ISO!

Relax✋, its not that big of a deal. Today's more modern DSLR bodies are well equipped to handle the high numbers with minimal performance drop. 👍

Furthermore, there's post processing software such as Adobe Lightroom. 🙌

In 'post' you can increase the 'noise-reduction' feature and come out with a smoother image.

Just don't let that power get out of hand and make everything look like its made of clay.... Or do so; it's your imagination.

Now go use your better understanding of expanded ISO to create more "creatively."

The art of is one that takes a little practice...
