What is Coring? revisted once again

[Piotr Wozniacki]

Thanks for this nice round-up! I'm playing with various picture settings to find my favorite looks and save them to my presets, and while I can see the effect of coring changes, I lack a knowledge of some theory behind it - what coring actually is, and what pay-offs there are for changing it, if any?

I don't understand what "coring" is or does either. I just followed a tip in another thread that it could reduce the noise associated with higher gain settings, at the expense of a "softer" image, which I assume means that it may look a little less well-focused. The impression I get is that if you just use a little bit of extra gain and a little bit of noise reduction you'll get nice pictures. If the weather's OK in my part of England at the weekend, I'll go out again and do some more experiments.

Coring slightly blurs areas of same or similar color, as a way of reducing noise - it sort of smooths out patches of color. For example, a little coring on a closeup in low light helps to smooth out noise on a person's face without making the entire image look soft.

As with any of these features, the best way to determine how they work is with your own eyes - play around with them and see.

Split this out from Mark Fry's "New A1 User Experiences" thread.

Piotr, if you have a question that isn't directly related to the original topic of the discussion, please post it as a separate thread. Please don't hijack another person's topic and try to turn it into something else. A separate topic (in this case, coring) means it needs to be in a separate thread.

Coring is a custom preset option that has been available on Canon camcorders for several years now, starting with the Canon XL2 back in 2004. Therefore, it follows that the subject of "coring" has been discussed on this site before. You need only to search through the XL2 and XL H1 boards to find the answers to your questions about coring. I just did a search and found several threads which discuss the coring function:

...and there are many others. So in the future, please don't hijack another person's topic, please use the Search function first before asking a question, because chances are high that whatever your question is, it's been asked and answered here before. The more we can consolidate topics, the easier it is for the next person to search for them. Thanks in advance.
