Re: Convert 8 to 16 bit for processing?

Because 8 bits has 256 discrete tones or colors and 16 bits has 65,536, does this suggest that 99.6% of the resulting 16-bit file represents "random data"?

Re: Absolute Difference

Thanks, Marpel
Since my "jpeg degradation" test was over 15 years ago, I can't recall if I was smart enough to use auto range. I suspect not. And as a result I may have misled myself into believing that the black result after multiple saves indicated no change in the file whatsoever.

Re: Absolute Difference

When starting out in digital photography over 15 years ago, I used this feature of PWP to verify the reported horrors of jpeg degredation through multiple saves. I ran a test in which I created multiple generations of the same jpeg image by saving each successive generation anew, thus creating a suc...

If you have a good monitor, it is likely that calibrating will make very little difference -- at the end of the process the calibration software shows you the before and after calibration of the same test image and I never see much of a difference...

A couple questions

This post is inspired by MarkT's recent post in which he said, "I remembered how I thought I*'d be happy with ver 7 for the rest of my life, as it just seemed so complete, but now I can't imagine life without ver 8." I log into this forum virtually every day to follow the progress of the d...

Re: Off-Topic -- Images

The simplest way would be a series of links to each user's own galleries since most folks either have their own web gallery or use Flickr or some other photo sharing site. This lets everyone display as many image as they want, and I have a few of those links already. I would like to occasionally sh...

Re: Using mask with Paint, Clone etc

The original idea in PWP 7 was to emulate masking fluid used by artists which covers part of a picture so you can paint over it and then peel it off, but it was really just confusing. I totally "get" that way of thinking about it. That mindset is one of the things I have always particular...

Re: Using mask with Paint, Clone etc

2) The mask works the reverse of how it works in PWP 7. You can paint where the mask is white and where the mask is black is protected. This is consistent with the way other transformations work. This is a welcome change. I have used masking for these "tool" operations in PWP 7 and always...

Re: Added ephemeris download

I still have that program on my computer sixteen years later. Is the program "revised" or merely the identical thing, "revived".

Re: Speck Removal Tool

My take is that the 'inner circle' should be read as 'inside the circle' - I think that the actual 'inner circle/spot' is just a un-adjustable symbol differentiating the active Speck (with the plus sign in the middle) from all the other/previous Specks. Even though I have not yet begun to use PWP 8...
