I'm using Photoshop Elements 9 for my post-processing. When resizing an image for dpc I use Image > Image Size to downsize to 800 px and then I save the file as jpg, using the quality slider to get an image of 300kb max.
In several forum threads I've read about saving for web as an easy way to resize and save the image for dpc. I do have that possibility under File, but it is not highlighted, therefore not usable. Does anyone has a suggestion to enable this option?

A second question related to downsizing: I understand that many photographers downsize their image to (say) 1300 px first, then perform another sharpening and then resize to 800 px. I guess this is to maintain a certain quality in sharpness, but maybe someone can tell me more about the reason(s) for this. Thanks!

I cant remember if you need to flatten all layers before saving for web or maybe make sure its converted ro 8 bit?

I tested in CS5, and you don't have to flatten an image to save for web, but it does need to be 8 or 16 bit.

As for your sharpening question, Kroburg, Google Adamus sharpening.

What's preventing you from using Save for Web probably is something with the file you are trying to save. To check if this is the case, open a plain old JPEG file and without editing anything try to save for web. If it's not grayed out, then your "real" work probably had a setting that is incompatible with Save for Web. As previously posted, high bit-depth images will prevent saving for web, as will some other settings. I'm not that familiar with Elements, so I'm not sure of the specifics.
With regard to sharpening and in addition to the recommended reading, one thing that I have found to be good practice is to resize to exactly double your intended size (if your end image will be 800x800, resize to 1600x1600) as a second-last step. Now carefully sharpen, then resize to the final size. Experiment with the amount and radius of sharpening of the 2x image, and with the resampling option on the final resize step. Use a high-detail image for the experiment. Now look at each result, and see which setting give you the best outcome. Each image is a little different, but you should find a basic workflow that gives you an outcome you like. The 800x800 isze is small, and some shots depend on a high level of detail for their impact. Getting the most visible detail, without excessive "crunchiness", visible halos, or other unwanted artifacts is, well, an art. It's surprising what a differenc optimizing the sharpening/resizing steps can make.
