Default How's this for sharp?

I'm a huge crane enthusiast and when one of the monster cranes comes to my neck of the woods I'm quick to grab my camera and take some snaps.

Having reviewed the pictures I took this afternoon I simply cannot get over how sharp this one is at 100% I love the detail and could get lost in this image for a long time - anybody like it?

Here is the image, first reduced then full size:

Canon 50D with Sigma 28mm f/1.8
1/25 sec
f/11
ISO 100

Note that we prefer that images be no larger than around 1024 pixels on their longest side for inclusion in forum posts so that members don't need to scroll around to see an entire image, not to mention that some members don't have high speed internet connections so larger file sizes can present a problem.

We have hard limits set at 1024 pixels on the longest side for dimensions, and a max file size of 260,000 bytes (approx. 253.9KB) for uploading and attaching images to posts here (with the forums software automatically resizing and recompressing images that exceed the limits set). But, we don't have a mechanism in place when images are hosted on other sites to do that kind of thing.

When you want members to see a larger original, it's best to include a link versus embedding it in the post. So, I removed the img tags from around the original, leaving a link to it instead that members can click on to see it.

No problem. It's not like we have that posted everywhere. So, when I notice very large images, I just let members know that we prefer no larger than 1024 pixels on the longest side. ;-)

Another way to handle it is making the smaller image act as a link to the larger image. Basically, you use url tags pointing to the larger image, while embedding the smaller one.

See the third example on this page (Making the image clickable):

Here's your image that way.

Really sharp! The big version shows lots of detail.

I made a sharpened resized version of your original. I will post both resized picks to compare. Tell me what you think about.
Left: yours / Right: mine.

Very nice, it looks razor sharp - did you use Photoshop?

Photoshop Eleements 8. The technique is this:

1. Resize your original. Sometimes a usual pre sharpening of the original is needed. Not on this pick indeed.
2. Apply Unsharp mask, Amount: 400 | Radious: 0.2 | Threshold: 0 (these setting may change accordingly to the pick).
3. In this case i repeated #2.

It works for resizing and sharpening for the Web and Email and its described Here. Excellent web site by the way. Cheers.
