<p>It may be because mine are centered and are surrounded by white space that they look smaller than yours.The landscapes are all 700px wide.</p>

<p>Doug, Have the dimensions been enlarged for photos, on here?</p>

<p>Doug - You have backup, right!!!??? Bummer, that it crashed.<br>
<br />Patrick - Thanks!</p>

<p>They were. I will try them out the next time I go on a shoot. Thanks.</p>

<p>"topic of this thread, which is sharp focus and background blur."<br>
Michael, actually it was subject blur or out of focus. I WAS going for background blur in some shots but the problem was subject blur. I know, it's been a long thread.</p>

<p>I post jpegs because I thought that's all we're allowed to post. I shoot RAW+. Interesting to know about the contrast setting.</p>

<p>David - What I should have added was "and raise the ISO to allow a faster shutter speed". On Pentax cameras, stabilization comes from the camera, not the lenses. Stabilization usually takes care of a few stops.<br /> I tried on-camera, diffused flash (9"x6" diffuser) but it was too harsh. It did crisp up the picture. Unfortunately, I had no neutral light wall to bounce from.<br /> <br />My basic problem was inadequate light. Here she is in adequate light and a breeze. I can't access the EXIF info at the moment to tell you all the info, but clearly that's sharper. I'm assuming my shutter speed was up there, probably 1/250+</p><div></div>

<p>Tim - Since the blur seems to be motion blur, I need to stop down from 2.8 to at least 4.0 (Is there truth to the theory that APS-C sensors add 1.5 stops to the aperture?) and make sure my shutter speed is at least 1/125 for the shorter lens and 1/320 for the long lens. And I should brace myself as well or use a tripod. By the way my camera is a K-5. If you could arrange for me to have a K-1, I'd love it.<br>
Oh, the post I mentioned regarding shutte speed being the reciprocal of lens length x 1.5 came from another site.</p>

<p>Tim, in thinking about this before posting and coming up with WTF?? (sorry about the language) I posted my question. Thinking about it today, it could be lack of going out and shooting often, thus not looking at shutter speed although I do remember looking but I was shooting at too low shutter speeds. The 70-200 is still heavy in my hands and focusing with the shorter lens seems to give me a hard time. I also forgot to use my 50 1.4 which might have been very useful. Again, not enough shooting.<br>
"he still can't distinguish between a shot affected by out-of-focus vs camera shake" For me, it's not always that easy.</p>
<p>"And didn't test first to narrow down the cause." Not sure what you mean.</p>
<p>I can't seem to find the post that factored in the APS-C sensor in the reciprocal of the lens length speed rule. Using that would probably have saved a few shots.</p>
<p>Any other thoughts? Hopefully, if I shoot with her again, I'll be able to post a few on the POTW.</p>

<p>My thanks to all, especially William W, for his forensic and encyclopedic reply. This place is still the best.</p>

<p>1/50th sec w/ 70-200. I think my question for that shot is answered! Methinks I should be using my tripod. Couldn't use it in the other area we were shooting in. I'll need to go through them one by on in Lr to see what's what</p>

<p>I took pictures of a lovely young lady the other day and many of them, if not most, seem blurry. I've magnified them in the lcd and it seems some have camera shake (with SR on and handheld) or just OOF and I've back button focused on her eyes. I was using the Tamron 28-70 @2.8 and the Tamron 70-200 @2.8. Can anyone tell me what kind of blur I've got in these 2 100% crops?</p><div></div>
