What can you use for dealing with JPEG 2000 files?

[Daniel D. Teoli Jr.]

There is an Archive that only gives out low-res garbage or fairly higher res JPEG 2000 files. I can't open the JPEG 2000 files in Lightroom or Paint or the photo viewer. They also have TIFF that is half-ass res, but you can't access it. (When I say half-ass res, it is about a 15mb TIFF and the JPEG 2000 is 4.2MB)

Here is an example of one of their file names.

This is the problem with lots of Archives. They are scum when it comes to open content sharing of material. Eventually I will write a thread about it at my blog.

What can be done with JPEG 2000?

Can no one use Google anymore?

Must everyone be spoon-fed information?

Add that to your blog post; the incredible entitled attitude of those who refuse to search for information themselves.

For one thing, JPEG 2000 does not require side-cart audio in the file of a scanned film, can retain  Rec. 2020 color space and frame rates...  enough.

Do some research.

I'd rather get the scoop from those that have tried things Frank. In other words, personal recommendations. You can spend a lot of time on Google and come up with a virus for your trouble by downloading free software. Or you can buy problem child's when someone could have steered you in a different direction.

This is a discussion forum Frank, so I offer topics of discussion. If someone does not want to discuss, no one is forcing them. When I see a post I don't like, I don't waste time on it...I just move on to the next post.

In any case, thanks for your input Frank. I will do some research on them.

So I haven't tried them? 

Glad you can ascertain that from a great distance.

I'll not impede your quest further.
