Hey Paula, you did pretty well here. Your aperture of 7.1 did well in getting a lot of sharpness here. Your not going to get the entire product sharp from front to back with whatever aperture you use, so don't worry about it too much. 7.1 - about 11.0 will be fine.

Forget about stacking, layers and other involved image editing. . .you don't need it to get a decent product shot to sell online.

What you have here is pretty good to go, but of course you will want to improve.
Is this window light? I would suggest moving the product further away from the background to reduce the shadow falling on it. Also, get two white boards and reflect light onto each side or at least the left side where the shadow is stronger.

Did you use a tripod? If you did and you should you can stop down even further to f11 or so, for a bit more sharpness throughout, but as I said before its not really bad here. A tripod is a good idea anyway

As for resizing, yes, sharpening is best after resizing. Typically, for an image this size you can use an unsharp mask setting of about .8 radius, 80 amount, and about 5 threshold.
What you did here looks very good, though.

Is this the true color of the pot? When I opened it in PS it looked much more gold and vibrant. It did not seem to have a color profile and when I assigned it srgb it remained that brilliant gold color.

If and when your using Elements, use the "save for web" command in the file menu and it will take care of setting it up for proper web display.

If you have not already, I would suggest taking at least three shots of each item from different angles. People usually like to be able to see a few sides of the product. This point of view is good, but also maybe another from higher up looking a bit down into the pot so we can see the interior and the rim.

I am going to move this to the studio and lighting forum where you can have our very own
Asylum Steve offer you some advice, as well as some of the other more experienced studio photogs that drop in there.

GB is referring to Clockwise lean meaning its slightly tilted to the right.
You did well, looking forward to seeing more.
