Another aspect of the wonderful world or orchids is photography, and the expansion of digital imagery has really been a boon. Over time, one can amass quite a collection, and you're bound to want to display them - individually or as a group.
Where to Post Images
You have several choices here. Many internet service providers allow you to create your own personal web pages at no charge, so you can pretty much do what you want. Alternately, there are free services out there such as webshots.com or pay services such as pbase.com, where you can maintain a portfolio of images. If your willing to post images individually, there is my favorite, the "Orchid Art and Pictures" forum at The OrchidSource as a web-based alternative, and the alt.binaries.picture.orchids NNTP newsgroup.
Resize Before You Post!
Many digital cameras offer a variety of size and resolution settings for the
stored images. Shooting and storing them at the largest size and maximum
resolution is preferred because that combination gives you the best overall
image. That image file, however, is NOT appropriate for posting online.
Below is a short guide, not "How to," but "Why" one should resize images:
So how does that affect the file size? Let's take for example a 600 x 450 pixel image. If it is black and white, each pixel only needs a single bit to describe the color - on/off or white/black - so our image is 270,000 bits or 33.8 kilobytes (kb) in size (8 bits = 1 byte). Adding additional bits to each pixel adds to the variety of "colors" available, but multiplies the file size. That same image at 65k colors (16 bits) results in a file that is 540 kb in size, and going all the way to the "true color" of 24 bits gives us a file that is 810 kb. (Those numbers do not exactly match the file size, as different file formats can include compression, it can vary based upon the number of colors you use from a "pallet," and when transferring or storing them, there are additional pieces of data attached to the file.)
Now for an image-size example... If you have a 600 x 450 image, saved at 150 ppi, the
"native" size will be 4" x 3" (600÷150=4, 450÷150=3). If it is saved at 75 ppi, it becomes 8" x 6".
Now then, if I was to post picture "as taken" with my digital camera as it is currently set up (2160 x 1440, at 24 bits/pixel, I'd be working with a 9.3 megabyte file (before jpg compression) and it would appear to be approximately 20" wide on my monitor, or almost 32" wide on the 640 x 480 monitor!
