<p>Just so you do not feel alone, I have the same problem of Lightroom creating the same standard size previews over and over again. When told to build them all, it scans for those missing, builds, then says it created the same amount of previews regardless of how many times I run the process. Found here; Library > Previews > Render Standard Sized Previews. For me it's 293 photos of my 32,016 photos imported into Lightroom 4.2. You can select all your photos and run this process or you you can select only one photo and a dialog box will pop up along the way asking if you want to build one or all previews. Same result both ways. The process did show some intelligence though because it alerted me of two TIFF files originally created by <em>Paint Shop Pro</em> which it could not make previews for. I opened those in <em>Photoshop CS</em> and resaved them. Next scan, there was no mention of not being able to make the two standard previews, but still the 293 were supposedly created.</p>

<p>I read some of the posts above, not all. I skimmed the OP link article. Artistic tastes of others sometimes get on my nerves too. I think that is the topic here. I have had two cameras as a photo hobbiest. I shot and photoshopped several years on both, the first was a Kodak Z740 point-n-shoot and the other one I still use is a Nikon D40 with 2 kit lenses covering 18-55 and 55 to 200 and an occassionally used F1.8 35mm. From these I've posted 3,600 images on flickr since 2006. In my mind the Kodak point n shoot rots in comparison. In my mind any preference for those Kodak images over the Nikon DSLR shots are like the iPhone-camera-love mentality. I look back on my old Kodak pics and think "UGH!" nasty. However, it seems just as many if not more of hits from viewers go to my old Kodak shots. Many of those look poorly exposed to me. Also the Kodak shots are much more noisy and I had to process the heck out of them to make them satisfactory in my mind, to the point where they look "artsy" though that was not my original intention. Some I do like, when lighting conditions were right. People tend to go to choose better composed point-n-shoot images on my photo stream but the colors or exposure or noise sometimes look ~BLEHH~ bad in my eyes. You can't zoom in much without cringing. The iPhone is like that. You are stuck with those limits on a sensor that size. People on Facebook seem to like it. I have female friends who don't seem to care how poor the quality is as long as it jars a memory. They like the conversation it stirs. It reminds me of birders who only want an ID on a bird, they do not care if it looks good. These people are not real image enthusiasts. iPhone camera devotees, if that's all they use, they are not real image enthusiasts, they just want a conversation on Facebook.</p>

<p>Ed, That just happened to myself, no histogram in the library module on a TIFF, and then the problem disappeared when I deleted a related file. Explained next,</p>

<p>I had 3 similar files in a row, all visible in my library: First the "original", an edited raw file now a TIFF in 16 bit. The second an edit of that version after being reworked with plugins in Photoshop then saved as a 16 bit TIFF also, it was renamed. The third was a copy of the reworked edit but saved as an 8bit JPG and given a unique name. None of them have any Lightroom History in the Develop Module other than importing. The one with no histogram in the library was the second one mentioned, the reworked TIFF. I wanted to delete the JPG because it was essentially a duplicate of the reworked TIFF with the only differences being that it was 8bit, jpg, renamed and it had served its purpose. As soon as I deleted the JPG, from both the hard drive and catalog, the histogram for the same looking TIFF it was next to was filling the histogram with colors from the Library Module where before there was nothing showing. Then I restored the JPG from the recycle bin and reimported it. All three now show histograms in the Library Module.</p>

<p>Why that happened I have no idea. I'm running LR v4.1. Perhaps your file with no histogram may be in the library with another file which has a very close copy type relationship.</p>
