I was like you when I started to shoot SLR, I thought the higher the F-stop the sharper the image, but then I learned about diffraction, for the most part f10-f13 should allow for plenty of DoF. You might just want to leave the shutter open longer, so instead of 30 seconds, do one full minute and see what that looks like. The starburst effect can be achieved by a filter if you really wanted to have it. I also learned that when doing good or real macro work, then you should use a higher F-stop, or if you were doing some homage to Ansel Adams. Personally I rarely shoot over f13, f10 in most cases for me is extreme. Hope this helped...

What's wrong with them that using a wider aperture would have fixed?

I just wanted to interject because someone came in here asking for advice, and what you told them is wrong. http://www.flyertalk.com/forum/16024858-post179.html Still had your bursts, although they make the image look busy if you want me to get technical, this isn't a photography website, so it doesn't matter, you like them that's fine. You just rarely shoot at that high of an aperture...read the following link and maybe you'll understand. FYI next time if you ever decided to print your image out at a high resolution it will look like crap.

But what's important is what you like. When (typically dpr-type) folks tell me what I should do to a photo, especially when it is about obeying certain "never do that" technical rules, I like to visit this site.

If you believe the details in my post above are wrong (though it's pretty much the same as your referenced thread), I'd be glad to discuss over at dpr - I have several thousand posts over the last decade there also.
Nothing's wrong with the images as posted for web usage. As I noted above, if you want to print these at 18x12 or so, the image degradation due to diffraction would be quite noticeable. But what's important is what you like. Digital/technical/gearheads get in the way sometimes.

What part?
And, you didn't answer my question. What's wrong with the images I posted that using a wider aperture would have fixed?

I don't think people understand how quoting works...WillCAD the advice you gave was wrong, and I did answer your questions, and so did the person above my last post...
