I can help…
Producing good quality images at a small file size for sharing on the web comes down to having the needed software to adjust compression rates. One of the more common pieces used is PhotoShop in one of its various versions. I use PhotoShop 6.0. Setting your camera to the lowest setting will work but it won’t allow you the option to print the photos later should that need arise.
Here’s what I do. I take all my photos at a medium resolution setting. I’ve compared print quality between the medium and high settings and can see no real noticeable difference so to save space on my memory cards, I opt for the medium.
After taking the photo, the file needs to be transfered to my pc and opened in PhotoShop. Once in PhotoShop, I crop out any material that is unnecessary to the subject matter of the photo (or might give away where I was fishing when I caught that last piggie ).
Next I resize the image to a max PIXEL dimension of 450. Why 450 and not leave it at the 1200 pixels as it comes off the camera? Most monitors are set to display 800 horizontal pixels and no more. I don’t want to force people to have to scroll up and down to see the whole image AND the large pixel size (sometimes refered to as PHYSICAL size) will result in an unnecessarily large file size that will require long download times.
Last, I mess with the amount of compression used when saving the file. I’m looking for a balance of quality and file size. In PhotoShop, I use the “save for web” option. This feature gives me access to an easy to use “slide bar” that I can play with to achieve that balance of quality and size. Once I’m happy with this balance, I chose a file name and save it to my hard drive.
I have included a screen capture of the “save for web” feature in photoshop. Notice I have the “quality” setting on the slide bar set to 60%. The resulting image from that setting will be posted immediately below followed by a second file, same image, saved at a quality setting of 30%.
Compare the quality of the two photos? How much difference can you see between them? Not much in my opinion and the second photo is a little less than half the file size of the first.
So… the answer is software. To post good quality photos on the web and have control of the file size, you need to lay hands on some software that will allow you to adjust the amount of compression used before saving the file.
Likely people are reading this and thinking the whole process sounds complicated and time consuming. It is not. Once you know your way around the software, an image can be sized, adjusted for color and contrast, brightened/darkened and saved for web in about a minute.
Any other questions, just holler.
