Image file changes

I recently made a discovery in the settings of the editing program I use
(Lightroom 3) that allows me to export my photos at a resolution of 1 dpi.
This has multiple benefits for both me and also to visitors of my blog and
website - more so when I've finished updating images on my sites.

Having the photos at 1 dpi makes the file size so much smaller so they load
much faster in the browser window. Also it makes uploading them so much
easier. But from my perspective there is also the added bonus of lessening
any concerns that my photos will be misused; which is a whole post in of
itself.

Image use and copyright is something all photographers have to keep in mind
when posting photos online. It's commonplace for images to be shared and
reposted, which as long as my metadata and watermark are still there and/or
I get image credit is something I'm okay with. My concern was more that
having high resolution images online could result in someone taking a photo
and printing it (possibly multiple times). Also with a high resolution image
my watermark could be cropped/edited out with minimal impact; unless I went
with the full image watermark that obscures the image.

Now, computer screens behave much differently to a printed image. Most
printed images are at least 240 dpi and sometimes much higher depending on
the printer. A computer screen however displays by a different process and
dpi has no bearing on how an image looks. Most images on the internet are
set at 72 dpi as this is generally used as the default. You will not see any
differences between a photo at 300 dpi and one at 72 dpi when viewed on a
computer screen (other than poor image processing and compression, which is
a different subject again). Taking this even further, you can convert to 1
dpi and it will appear onscreen to look as good as a photo at 300 dpi.
However, try printing either and you will most definitely see a big
difference.
