I mean really, can I really trust a 3&#8243; LCD to give me all the information I need to determine if I got white whites and black blacks and a nice distribution in between?  No.  I know I can&#8217;t.  It&#8217;s not perfectly true to colors, and sure can&#8217;t be trusted to give me a fail-proof representation of exposure.  Sure, the D300 has a nice bright LCD, but can I take a photo and review it and expect the LCD to look the same inside or outside?  No, I can&#8217;t.  Do I know this?  Yes, I do.  Do I keep getting suckered in?  Yep.  You betcha.  Without a doubt, and to the point I&#8217;m starting to worry about my sanity.  You know the old saying right?  Insanity is doing the same thing over and yadda, yadda, yadda&#8230;<\/p>\n<p>Case in point?  Here &#8217;tis.<\/p>\n<p><!--more-->I was shooting Jacqui in a low-light elevator lobby in the Mid-Continent Tower in Tulsa.  I was using a single SB-800 propped on a trashcan below and to the right of camera axis.  I had a full cut of CTO on to balance with the tungsten lighting and was using a Honl Photo 1\/4&#8243; honeycomb grid to get a nice tight light on Jacqui without spilling around and behind her.  I was using a Lensbaby 3G, which has nothing to do with this topic, but it&#8217;s sure cool to point out.<\/p>\n<p>So I take a shot or two and tweak the flash output using the on-camera Commander mode.  How am I checking the exposure and lighting?  With the LCD of course.  I mean, that is the entire point of this post, eh?<\/p>\n<p>So a couple of shots and I&#8217;m rocking it.  Now I&#8217;m just trying to get a good set with the Lensbaby to get her eyes nice and sharp while throwing in that awesome Lensbaby blur away to the edges.  About five shots and I&#8217;ve got it all.  Light, focus, blur, all nailed.  Money shot.  Looks great, show Jacqui and she digs it, or is just being really polite.  Either way, I&#8217;ve got it and I&#8217;ll be happy if I don&#8217;t get another good shot all day.  It&#8217;s that good.  Here&#8217;s a low-tech screen shot just for proof.<br \/>\n<img decoding=\"async\" src=\"http:\/\/farm4.static.flickr.com\/3235\/3300032971_8e56b19c1d.jpg\" alt=\"Back Before\" \/><\/p>\n<p class=\"clear\">&nbsp;<\/p>\n<p>Well, I thought it was that good until I got it home and dumped it into Bridge.  I&#8217;ve found Bridge can be a real ego compensator compared to the LCD.  The LCD says &#8220;you rock&#8221; and then Bridge says &#8220;Serious?  You&#8217;re really serious?&#8221;  Here&#8217;s the proof.<br \/>\n<img decoding=\"async\" src=\"http:\/\/farm4.static.flickr.com\/3623\/3300032879_09b60615b8_m.jpg\" alt=\"Image Before\" \/><\/p>\n<p class=\"clear\">&nbsp;<\/p>\n<p>Wait a minute.  It looked good on the back display when I shot it.  Wait another minute.  Haven&#8217;t I been here before?  Yep.  About every time I&#8217;m shooting in low light.  Here&#8217;s what the histogram on this one looked like.<br \/>\n<img decoding=\"async\" src=\"http:\/\/farm4.static.flickr.com\/3328\/3300032857_674afea30f.jpg\" alt=\"Histogram Before\" \/><\/p>\n<p class=\"clear\">&nbsp;<\/p>\n<p>So if I&#8217;d been paying attention to, and believing in the histogram on the camera?  Pretty much the same thing.<br \/>\n<img decoding=\"async\" src=\"http:\/\/farm4.static.flickr.com\/3548\/3300864480_65081971ef.jpg\" alt=\"Back Before\" \/><\/p>\n<p class=\"clear\">&nbsp;<\/p>\n<p>The D300 has a 12-stop spread from black to white, and here I&#8217;ve managed to compress all my pixels in the bottom third of that dynamic range.  Not what I was after at all, and sure not what the display really looked like.<\/p>\n<p>So I don&#8217;t want to lose the image all together and I jump in to that all too familiar &#8220;save it in post&#8221; mode.  Tweak here, tweak there, thank God for Adobe Camera Raw.  Here are the develop settings that got me there and the resulting histogram.  If you&#8217;re familiar with these settings, you can see how far I had to push.<\/p>\n<p><img decoding=\"async\" src=\"http:\/\/farm4.static.flickr.com\/3301\/3300864106_a6dac64991.jpg\" alt=\"Pulling it out of my ...\" \/>&nbsp;<img decoding=\"async\" src=\"http:\/\/farm4.static.flickr.com\/3125\/3300864130_8895a9127b.jpg\" alt=\"Results\" \/><\/p>\n<p class=\"clear\">&nbsp;<\/p>\n<p>&#8216;Course you go pushing exposure to +2.25 and brightness to +50 and here come &#8216;da noise.  Funny how trying to correct one mistake leads to others.  When will I learn?  When, when, when?  Trust your histogram.<\/p>\n<p>So a run through Imagenomic Noiseware Pro and I&#8217;ve got something presentable.<br \/>\n<img decoding=\"async\" src=\"http:\/\/farm4.static.flickr.com\/3305\/3300032553_8770e76a4e_m.jpg\" alt=\"Finally.  A decent product.\" \/><\/p>\n<p class=\"clear\">&nbsp;<\/p>\n<p>It also occurs to me maybe, just maybe, I&#8217;ve got the display brightness up too high on the camera.  I checked, and it&#8217;s set to the default of 0, but just to help me out next time I get dense and forget the histogram, I adjusted it to be a little more realistic.  If it&#8217;s not bright enough for outside, I&#8217;ll adjust it back when needed, in fact I even saved the LCD Brightness menu to the customized menu.<\/p>\n<p>So now, with the LCD brightness set to -2, this is what I&#8217;m seeing.<br \/>\n<img decoding=\"async\" src=\"http:\/\/farm4.static.flickr.com\/3331\/3300864082_4d12bbd079.jpg\" alt=\"Reality adjusted\" \/><\/p>\n<p class=\"clear\">&nbsp;<\/p>\n<p>So, lets see if I can do better in the future.  I mean Skywalker trusts the Force and destroys a whole Death Star, surely I can trust a histogram and score an image or two.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>You&#8217;d think I&#8217;d have enough experience using a fancy-schmancy digital SLR camera, I&#8217;d have learned by now to trust something besides the digital display on the back to determine if I got the exposure correct for the shot or not.
