Hi, I'm curious about the reasons why some restorers resize photos - either during the restoration process or before posting their restores. I'm not critical of this, just hoping to learn more!
I don't usually look at the details (dimensions, file size) of posted restores, just admire (and learn from) the quality and style of restored photos On the 'Joan Chapman' thread (
http://www.rootschat.com/forum/index.php?topic=792406.0), I noticed that some restores had been resized to about 50% - 60% of the original dimensions (in pixels). In other words, the original scan resolution had been reduced by 40%-50% in the posted restores.
I've always thought that maintaining the highest (original) resolution - especially in fine details - is something to aim for. A loss of resolution probably won't be noticeable unless a photo is printed or viewed on a high resolution screen at some point. I accept that there is a trade-off between 'number of pixels' and 'JPEG compression level" to get the best quality photo that doesn't exceed Rootschat's 500 KB limit. But looking at the size of the posted restore files, resizing didn't seem to me to be related to reducing file size.
I can only think of two other reasons to resize (and reduce the original resolution by 40%-50%) other than reducing file size. One is that the photo then fits on the Rootschat screen (without horizontal scrolling). The second is that some editing tools (such as blur) can be more effective on smaller photos in achieving the desired results than on larger ones.
If you sometimes resize photos either during the restore process or before posting your restore, I'd be interested to read your reasons for this.
Thanks in advance,
Mike
