Default Why I like my K-x and the DAL 55-300mm

Other than the soccer pic, the rest of these were taken yesterday evening. All were shot handheld, even the moon at full zoom. Some HDR PP on the mushroom and landscape, but the rest are straight out. (Some w/ cropping and all with resizing. These are all beautifully crisp at full size.) I love this K-x and lens combination...

Quite a diversity of subjects & moods - nicely done! Great mood in the sunset with grasses, fine action in the soccer shot, and great illustration of the puffball.

PS - if you want to maintain that great crispness of image when resizing, you might want to apply some sharpening after resizing...

Thanks. It was the versatility of this combination I was mainly highlighting.
As for the EXIF, I'm still pretty new w/ this DSLR and paying attention to EXIF. I see that it was only saved on the puffball and landscape pics, but got stripped on the rest. Those were the 2 I ran through AutoHDR which I had also set to resize down during the processing to the 1024 max allowed on this site. So, when I resized the others, something happened... But the versions on my computer which I uploaded all have the EXIF data attached. Did it get stripped when I uploaded? Is there some other way to "attach the EXIFs"?
I did some searching on this forum and found out about the Firefox plugins and the PhotoME program.

In any case, using PhotoME, here's the EXIF for the sunset w/ weeds pic:

I used a different program (IRFANVIEW) for resizing. Let's see if that preserved the EXIF.
Hmmm... I just checked and still no EXIF. I did remember to check "Save EXIF details" when I saved it in IRFANVIEW, and I can see the EXIF data on the file on my computer which I uploaded. Am I doing something wrong when uploading?

Yes. If you exceed the maximum allowed sizes for either dimension or file size, the forums software will still try to let you attach the image to a post here. But, it will attempt to resize it, then recompress it (which can result in softer images), and strip out the EXIF info.

When you use the Manage Attachments feature to upload a photo, you'll see the maximum allowed sizes listed.

The longest side of the image dimensions should be no longer than 1024 pixels, and the file size should be no larger than 253.9KB (260,000 bytes). Otherwise, the forums software is going to resize/recompress the images and strip out the EXIF info.

When using Irfanview to resize an image, make sure the longest side is 1024 pixels or less. Then, tweak the JPEG Quality slider you'll see when using the "Save As" choice until the file size is no larger than 253.9KB.

Usually, if you use an image size of around 800 pixels on it's longest side, a slider setting of around 85% will keep the file size within limits. With a larger image, you may have to use a bit more compression (try 80% quality if the file size is too large).

As long as the image is within the maximum allowed sizes you'll see when using the attachment manager (paper clip icon) to upload an image, the forums software will not modify it.

Irfan view also has an option to save to a predetermined file size, and will adjust the compression to fit. (if you have installed all the plugins along with Irfanview)
If you use a quality number, the file size varies based on the amount of fine detail in the picture.

Thank you all, both for the compliments and the suggestions.
@JimC: You did indeed identify the problem. I had set the maximum pixel lengths, but I failed to check the file size. All the ones I uploaded that were larger than 253Kb had the EXIF stripped.
@VTphotog: So, I did I you suggested. I installed the "riot.dll" plugin for Irfanview which allows me to set a desired file size.
So, let me try another one. I was using the "sports" mode and using the fast capture. The pic is, of course, the initial shot with overlays of subsequent action. Another reason to love my KX and the long zoom!
