Office Picture Manager - Lossless editing?

[Mike]

Until now, I have been using ACDSee for my photo editing/managment. Today, I
discovered the Office Picture Manager and like it's simplicity (granted
ACDSee isn't too hard).

Anyhow, I was wondering if anyone knows whether or not the editing (red eye,
rotate, crop, etc) is lossless. I'm not even sure my understanding of
lossless is correct but, when I work in ACDSee, I have the option to "force
lossless" which I believe ensures I maintain image quality.

Will any changes I make using Office Picture Manager maintain the image
quality?

Hi Mike,

In a way it's a "trick question" <g>. If the file format you start with is a JPG file format and save again to JPG (which is a
lossy format) you would be 'losing' content of the graphic, but the loss isn't always noticable, depending, in part if you're going
to do on screen viewing or printing. Also, if you use 'compression' or change one of the JPG option settings from File=>Export
(i.e. choose smaller file size over larger size with higher quality) that can also affect the result. You may want to take a
picture or two, keep a copy of the untouched original and check the results, printed, if you're not limiting the use to onscreen,
before keeping only an edited picture.

Basically, it can be a matter of what is 'good enough' for your needs rather than an absolute 'if you do this, the result will
be'...
when it comes to your pictures.

Thanks for your answer which does help a lot. Would I be able to tell if the
picture lost quality by looking at the file size or resolution? Or would this
only be something that would be noticeable when looking at the picture (on
screen and on paper)?

OK. Thanks again for your help!

Hi Mike,

The resolution (size in the case of Picture Manager) probably wouldn't tell you. The file size in a before and after scenario could
help identify if compression was applied if no resizing of the picture was done, but testing a couple of pictures printed is a more
accurate measure. The settings for brightness/contrast on your PC monitor, for example, could fool you into thinking you've made a
picture clearer or brighter, but when printed you could find that it has instead done a 'washout' of the color if the monitor was
set too 'dark' for realistic photo editing.
