Guest malland Posted December 9, 2010 Share #1 Posted December 9, 2010 Advertisement (gone after registration) Generally, with a calibrated monitor exported JPGs and TFFs look the same in terms of brightness, contrast and colot. Last night, however, I had a rather dark image that was problem: the exported JPG file is much lighter than the TIFF. I think it's an Aperture problem because when I take a screen shot of the image from Aperture the resulting JPG file is as dark as it should be. Incidentally, when I export the original image, without any adjustment, the resulting JPG file is also the same as the TIFF. (The adjustments are Definition, Sharpen, Edge Sharpen, Curves, and Exposure increase), Also, I noticed that when I made a duplicate version this file in Aperture and then removed all the adjustments and then undid the removal of the adjustments, the duplicate image is a somewhat different from the original image: it should of course be the same. Has anyone else come across this problem, or have a solution? —Mitch/Manila Paris au rythme de Basquiat (WIP) Link to post Share on other sites More sharing options...

vanhulsenbeek Posted December 9, 2010 Share #2 Posted December 9, 2010 Mitch, are you perhaps exporting to a different colorspace? Link to post Share on other sites More sharing options...
Guest malland Posted December 9, 2010 Share #3 Posted December 9, 2010 Looking at the Metadata File Info in Aperture, shows the "Color Model" to be "RGB"and I'm exporting a JPG with a Color Profile of sRGB, which I would think is a normal conversion. —Mitch/Manila Paris au rythme de Basquiat (WIP) Link to post Share on other sites More sharing options...
vanhulsenbeek Posted December 9, 2010 Share #4 Posted December 9, 2010 Hmm...... I do not know the colorspace RGB, only sRGB, AdobeRGB, Prophoto etc. RGB is, in Photoshop, a 'Mode', as next to LAB, CMYK, Grayscale and the like. But I suppose that is the colormodel of the RAW file, which has no colorspace assigned yet. Lightroom, AFAIK, does not work in a colorspace, and it is only assigned when exporting, or editing in an editing program. So, on first sight, your problem is not in this field.

Guest malland Posted December 9, 2010 Share #5 Posted December 9, 2010 Sander, I think your analysis is correct. From my other information given above, I think that there is an Aperture glitch related to the use of certain adjustments, since the unadjusted file as a correctly toned and colored JPG. —Mitch/Manila Bangkok on My Mind Link to post Share on other sites More sharing options...
andybarton Posted December 9, 2010 Share #6 Posted December 9, 2010 Have you posted this on the Aperture section of Apple's website help facility? Does it happen if you use a Leica jpg? Link to post Share on other sites More sharing options...
Guest malland Posted December 9, 2010 Share #7 Posted December 9, 2010 Advertisement (gone after registration) Have not yet gone to the Apple site, as I've been busy and not familiar with the site. Good idea. Will do this weekend. I've only been using DNG as input files, not JPG. —Mitch/Manila Paris au rythme de Basquiat (WIP) Link to post Share on other sites More sharing options...
richfx Posted December 10, 2010 Share #8 Posted December 10, 2010 I've had repeated problems with Aperture 3 losing my adjustments and at other times not applying them. Photos will open up as adjusted, then become much lighter and unadjusted. It has required repairing permissions and repairing and rebuilding the database numerous times to correct, but only temporarily. There's definitely a glitch in Aperture - rather frustrating to lose all of your adjustments repeatedly out of the blue. This problem seemed to coincide with the 3.1 update and the very large Snow Leopard / OSX 10.6.5 update some weeks ago, both of which came out almost the same day. I hope that Apple is aware of it.

Strobist Posted December 10, 2010 Share #9 Posted December 10, 2010 a new update just came out today. give it a try and maybe it has addressed your issue. Link to post Share on other sites More sharing options...
Guest malland Posted December 10, 2010 Share #10 Posted December 10, 2010 I just downloaded this update and the problem remains. I'm now fairly certain that the problem involves Aperture not correctly applying some of the adjustments listed in my original post when exporting JPG files. For example, I reprocessed a version of the original DNG file without any Aperture adjustments and then applied new adjustments using the Viveza plugin, which generates a new TIFF file: when I exported an JPG from the file produced by Viveza, that is, a file without any Aperture adjustments, the JPG thus produced looks the same as the TIFF. —Mich/Manila Paris au rythme de Basquiat (WIP) Link to post Share on other sites More sharing options...
Guest malland Posted January 15, 2011 Share #11 Posted January 15, 2011 Still haven't found a solution to this problem: Aperture export files without applying all the of the adjustments, so that often the exported files are much lighter. Has anyone found a solution to this? —Mitch/Bangkok Paris au rythme de Basquiat (WIP) - a set on Flickr Link to post Share on other sites More sharing options...
Guest malland Posted January 23, 2011 Share #12 Posted January 23, 2011 I've now found that the major cause of the lighter exported files is the us of "Edge Sharpen": if I remove the Edge Sharpen adjustment the exported JPG is almost as dark as the image in Aperture, but not quite so. I also find that using the Sharpen adjustment also causes the exported file to be a little lighter, but much less so than Edge Sharpen. All this has made me lose faith in Aperture as a professional application: the Edge Sharpen but, which I tried out because I read somewhere on the web that it was a problem, is a major fault to have in the third version of Aperture. It's very frustrating because I have several thousand files processed with Aperture. Not ure what to do now. —Mitch/Bangkok Early Morning Market at Pak Nam Pran Link to post Share on other sites More sharing options...
andybarton Posted January 23, 2011 Share #13 Posted January 23, 2011 Why not remove the sharpening, export the file, apply sharpening in PS, via an action and then save again? I'm surprised you need lots of sharpening. Link to post Share on other sites More sharing options...

I'm surprised you need lots of sharpening. These are very light sharpening adjustments that I have consistently been applying. Removing them did not make a significant difference. —Mitch/Bangkok Tropical Light Link to post Share on other sites More sharing options...
Guest malland Posted January 23, 2011 Share #16 Posted January 23, 2011 Why would a " Edge Sharpen" command result in a lighter or darker export?Of course it shouldn't. This is clearly a bug in Aperture or a combination of OS X and Aperture. (I'm using the latest version of both on a MacBook Pro with a 17-inch high resolution monitor. Here's some more information in case someone else has this problem: 1. The issue is not with the TIFFs from my scanner, it's with the problems caused by the Edge Sharpen adjustment and, to a much smaller degree, by the Sharpen adjustment. The reason I almost never faced it before is that, when working on RAW files from digital cameras, I always processed them using Silver Efex and Color Efex, which create their own TIFFs to which I never applied either Edge Sharpen or Sharpen. (In the past I applied Edge Sharpen and Sharpen to the "base file", which I then processed with SIlver Efex or Color Efex, which in turn produced a new TIFF file to which I had no reason to apply Edge Sharpen or Sharpen, and therefore had no problem in exporting from Aperture.) 2. I have had this problem in a couple of cases in which I processed DNG files from a digital camera entirely in Aperture using Silver Efex or Color Efex on the file to be exported. 3. I found several threads on the web on the Edge Sharpen problem — I haven't kept the URLs — which is the reason that I tested what would happen when I unchecked Edge Sharpen in Aperture before exporting the file and thus found that this was indeed a problem. These, threads some of which, as I recall, were over six months old showed that some people were having this problem while others were not, and there was no solution — and there still does not seem to be a solution. This is clearly a major problem, of which I would assume Apple must be aware because of those threads, some of which I think were on Apple forums. —Mitch/Bangkok Bangkok Hysteria©: Book Project Link to post Share on other sites More sharing options...
kevinparis Posted January 24, 2011 Share #17 Posted January 24, 2011 mitch please stop referring to this as a major problem.. If it is is a problem with Aperture and not with your particular workflow then report it to Apple. I csn't recall whether Edge sharpen is an adjustment that was part of the original Aperture tool set and therefore is only there for legacy purposes.

Guest malland Posted January 24, 2011 Share #18 Posted January 24, 2011 It is a major problem for me because it means I can only use Aperture as a base for Silver Efex and Color Efex, and, these days, I'm traveling frequently and simply don't have the time for this. In a search on web I found the following posting for a problem that John Thawley was having: I tried the solution that he used (at the bottom of his posting), but the problem persists. http://www.johnthawley.com/journal/2010/4/24/aperture-3-is-broken.html Just having gotten back from the Philippines, I have to leave for a month in the US and UK and won't be able to process photos or spend time on trying to find a solution. In fact, just now I've spent more time on this than I can afford. Therefore, if someone does find a solution, I would be grateful if he or she would post a reference to it here. —Mitch/Bangkok Paris au rythme de Basquiat (WIP) Link to post Share on other sites More sharing options...

Aperture is much more than a way to use silver efex... if thats all that important to you then delete Aperture and be happy with Photoshop... you obviously don't understand what Aperture is all about Link to post Share on other sites More sharing options...
Guest malland Posted January 24, 2011 Share #20 Posted January 24, 2011 Kevin, get a grip! Why do you accuse me of such an absurd thing as using Edge Sharpen only because I "read that there was something wrong with it"? The problem is not that I don't understand Aperture: I know it well. In the past when processing RAW files I've always used Sharpen and Edge Sharpen, together with Definition and Black Point and Recover, and White Balance for color, as the base adjustments in Aperture before going into Silver Efex or Color Efex. After getting the TIFF produced by the latter two plugins, I would sometimes apply a light contrast increase with Levels and never had an export problems. It is only now, when I've gone back to film and scanning, for which I don't need Silver Efex or Color Efex, and want to do all the final processing in Aperture, that I find I have a problem when exporting files to which Edge Sharpen and Sharpen have been applied. This bug has been encountered by other people and, as far as I can see, no solution has been found or announced by Apple. It will be time-consuming to find a solution and I simply don't have to tike for this now, which is frustrating — not to speak of the frustration that applying Edge Sharpen lightly should not result in an exported JPG file that is so light in tone that it bears little relation to what is on my (calibrated) monitor in Aperture. —Mitch/Bangkok Scratching the Surface© Link to post Share on other sites More sharing options...
