style="text-align: justify;">As promised yesterday, today I will be talking about bracketing your exposures based on shutter priority.  After a couple comments yesterday that it seemed unusual to bracket on aperture rather than shutter speed, I felt that in this companion post I should acknowledge that, it is.  The reason for the post?  One of the downsides I mentioned is that your depth of field will change considerably from a wide open setting to that of, say, f22.  That can also be an upside though because as you merge bracketed exposures into an HDR image, you can also add depth of field if you make the adjustments in aperture priority over shutter priority.</p><p
style="text-align: justify;">Additionally, I led off with aperture priority because it&#8217;s not the norm, and as most readers will know &#8211; I try to approach things from a new perspective when possible.  Finally, as I followed up with in the comments section, the simple fact of the matter was that I could not remember whether 250 or 200 was the absolute middle point for shutter speeds (this is the risk of adding gray above the brain, rather than to the brain! *grin*).  So, I led off with the post where I knew the numbers rote! <img
src='http://www.canonblogger.com/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /></p><p
style="text-align: justify;">So, in the interests of full disclosure, shutter speed is a more common way to go when making bracketed exposures.  After verifying my numbers in camera, here&#8217;s how it breaks down using shutter speed to bracket multiple times:</p><p><img
class="aligncenter size-full wp-image-1191" title="fstopshutter" src="http://www.canonblogger.com/wp-content/uploads/2009/03/fstopshutter.jpg" alt="fstopshutter" width="650" height="200" /></p><p
style="text-align: justify;">I also realized that I did not give the step-by-step yesterday, so here&#8217;s the process I would follow:</p><ol
style="text-align: justify;"><li>First, meter the scene, set your camera to ISO 100 and exposure priority and adjust to 1/250th of a second.  Check where your f-stop is.</li><li>Second, switch to manual, and adjust all settings to match that metering.</li><li>Third, adjust the shutter speed down to 1/30th of a second, and fire off 3 exposures and the camera will bracket over and under one stop.</li><li>Fourth, adjust the shutter speed up to 1/250th of a second, and fire off a second set of three exposures (the camera will bracket over and under one stop).</li><li>Finally, adjust the shutter speed up to 1/2000th of a second and fire off your last set of three exposures.</li></ol><p
style="text-align: justify;">Voila!  You now have 9 exposures to merge together for a bracketed workup to take advantage of a high dynamic range, or for exposure blending, as desired.  Of course the same rules from yesterday also apply:</p><ul
style="text-align: justify;"><li>Be shooting on a tripod</li><li>Be using a remote release (or timer)</li><li>Be using mirror lockup</li><li>All other settings remain constant</li><li>and that lighting conditions aren’t changing appreciably</li><li>You are set to manual focus</li><li>Your lens is set to its hyperfocal distance</li></ul><p
style="text-align: justify;">Any final thoughts to share on how to bracket exposures?  Anything I missed or additional tips to share?  Feel free to sound off in the comments section!  In the meantime, Happy Shooting and we&#8217;ll see you back here again tomorrow!</p><div

style="text-align: justify;">I was driving home from work yesterday with my camera bag in the seat next to me when I saw this on the opposite side of the road.  So, I swung around, popped out of the car, set up and used the roof of the car for stability and snapped off a few shots wide open and about 800 ISO.  As a full-size image it is a bit noisy, but here it looks pretty good.  To me, that&#8217;s proof positive that it always pays to have your camera with you.  That&#8217;s the &#8220;Tuesday Tip&#8221; for this week.  Enjoy and Happy Shooting!  We&#8217;ll see you back here again tomorrow.</p><div

The lucky readers (lucky possibly being a subjective term in this case) will get a sneak preview of my latest gallery addition as I ran out of time and do not have a link on the site to this yet (or the thumbnail for that matter).</p><p>On the blog maintenance, I&#8217;ve changed the notice for comments &#8211; apparently the spam flag was set a little too severely as people were making comments and it was taking up to a month in some cases before those got discovered and re-tagged.  So, your comments should become visible much more quickly now.  With that in mind, I thought I&#8217;d also share the latest photo gallery that I am putting up on my website with those of you who are tuning in, so now you can comment more easily!  Last but not least, I had mentioned an article that was forthcoming both in the video tutorial last week, and in another one of the posts.  Well, after going through several re-writes and different takes on it, I&#8217;ve decided not to publish that, as it&#8217;s just to dense of a topic for a short listen or read.  If anyone is interested in it though, the subject is creative development.</p><p>I looked at an essay that came out in the most recent issue of Shutterbug Magazine, where Jack Hollingsworth looks at how photographers develop their in the essay <a
href="http://shutterbug.com/columns/passport/0608passport/" title="The Ladder:  In Defense of Imitation"  target="_blank">The Ladder: In Defense of Imitation</a> .  He defines 3 stages or phases of development:  imaginative, adaptive, and innovative.  While both interesting and logical, it raises more questions than it answers.  I found myself in similar shoes when trying to address just a few of those questions ir raised in my mind &#8211; more questions, practically all of which were subjective in nature.  So, the article will likely not see the light of day here at CB.  If anyone <strong>is</strong> interested in a heavy read, let me know via email and I&#8217;ll be happy to forward a copy of that article to whomever requests it directly.</p><p>That said, the blog was not a good place for it, so I discarded the idea for CB and went with the photo montage.  A sneak peak was done a few weeks ago, and it&#8217;s now complete.  Visit my photo site for the full gallery <a
href="http://www.jasons-photography.com/galleries/kids" title="Jason Anderson Photography"  target="_blank">here</a></p><p>Hope everyone&#8217;s weekends were good ones.  Here&#8217;s to a new week &#8211; happy shooting, and watch <a

When that routine got disrupted from some dental and sleep deprivation issues the other day, I didn&#8217;t realize until just a short time ago that the post for Friday had not been scheduled.  Not only had it not been scheduled &#8211; it didn&#8217;t even get written yet!</p><p>So, a thousand pardons as I rush to get a somewhat photo-related post out before the end of the day.  Since it is on short notice, I will simply relay a funny story that happened to me the other day as I was out walking the dog.  I had taken the camera and flash with diffuser attached as the day was actually perfect for photography: late afternon, cloudy skies, and evenly light all around.  So, I am bouncing along, trying different settings here and there with various subjects &#8211; a flower, a reflection in some water, and I have the bright idea to do a macro shot super close on a flower.  But, instead of going wide open to get available light, I figured let&#8217;s try the flash here &#8211; so I pop the flash on, attach the diffuser and set it to ETTL.  Then I dial the aperture down as far as I think it can go on the fill flash setting &#8211; f22!  I pre-focused on the lower third of the frame, then set the focus to manual.  Finally, I shifted the camera up just a smidge, knowing that the lower portion would be in focus and because of the f-stop, I would have a pretty solid dof throughout.</p><p>Well&#8230;there&#8217;s always something you forget, and in this instance, it was the ISO setting.  You guessed it &#8211; 1600!  ARGH!  Well, I cleaned it up a little with NN after the fact, and yeah, it&#8217;s okay, but imagine how this shot would have been without the noise and tack sharp?</p><p><a

src="http://www.canonblogger.com/wp-content/uploads/images/_MG_0258_small.jpg" alt="Floral Macro" width="499" height="335" /></a></p><p>So, it seems another one that got away from me!  I think I am going to tape a label to the back of my LCD and write on it in big fat letters <strong><span
style="color: #ff0000;">ISO</span></strong>!  Long story short &#8211; always double check your settings, and always take a few shots.  I only took the one, so it&#8217;s all I had to work from.  Oh well&#8230;better luck next time!  Hee&#8217;s your traditional WTD episode for Friday:</p><p><a
