I was in a location where a couple of the departures from SEA were overflying me. I happened to have the camera to hand (of course I did) and I had the polarizer on there at the time. I had an Alaska Airlines 737 (what a shock from SEA) and a Hawaiian Airlines A330. I grabbed a few shots. The thing I like about the polarizer is cutting down on the glare from the white fuselages but they were still pretty bright. The rest of the sky was darkened considerably and, when editing to address the white fuselages, even more dark. I quite like the deep and moody look it gives to the shots with very little editing involved. Both jets pulled some vapor as they came through the same area so clearly there was extra moisture in that one spot. Maybe it was a thermal?
I’m not sure whether too many people noticed but a few weeks back, this blog briefly went offline. I had got a warning email from my hosting company that I had some content on the site that was not consistent with my plan. One of those files was an old file I had stored there to share with someone so I deleted it. The other was a folder that a backup plugin uses to create temporary files that are then sent to a cloud service. I left that one alone.
I got a second email with a similar warning, despite the first file having been deleted but discovered that the account was already suspended. There then followed a fair bit if discussion with their tech support to give me enough access to allow me to actually delete the files. When I got in via FTP, I came to see their worry. The backup folder is supposed to be emptied after the files are copied off. That is happening fine now but there were two years of daily backups sitting in there that never got deleted. Over 4,00 zip files with a huge amount of data in them. No wonder they were annoyed.
Deleting them took a while to do, not least because they took longer than the temporary access period I had been granted so we had a few cycles of getting back in again. However, they all got removed eventually and I was allowed to go back to normal.
The most recent update for Adobe Photoshop includes a function called Super Resolution. Many of the third party plugins and stand alone image processing tools come with tools to increase the resolution of images. In Photoshop you used to have a basic way to increase resolution but it wasn’t that clever and could introduce odd artifacts. I had been advised to use it in small increments rather than one big increase to reduce the problems but I hardly ever used it.
The new addition to Photoshop is apparently based from machine learning. If the PR is to be believed, they took loads of high res images and low res versions of the same image and the machine learning came to recognize what might be there in the small shot from what it knew was in the large shot. I don’t know what the other packages aim to achieve but this new tool in Photoshop has been doubling the resolution of the shots I have played with. You end up with a file four times the size as a result of this doubling of dimensions.
I have tried it out on a couple of different shots where the resolution was okay but not terribly large and where a higher res shot might prove useful. So far the tool is available through Camera Raw in Photoshop – not Lightroom. You need to update Lightroom in order to import the DNG files it produces. There is a suggestion that Lightroom will get this capability in time which would be more user friendly from my perspective.
My computer is not cutting edge so it takes a little while to process the images. It forecasts five minutes but seemed to complete the task way faster than that. In the examples here, I attach a 200% version of the original shot and a 100% version of the new file. There seems to be a definite benefit to the output file. I wouldn’t describe this as earth shattering but it is useful if the original file is sharp enough and I might have a need for this for a few items over time.
My main cameras have two card slots. One is a CFast and the other is Compact Flash. I use the CFast all the time but the Compact Flash is a handy backup. Occasionally, if I have the camera on with the CFast out of the slot, the camera reverts to the second slot and, if I don’t notice, it continues to use it when I next shoot. This isn’t a particular problem except when it comes to downloading. I have USB3 card readers for both CFast and Compact Flash. However, the speed of card technology has moved on dramatically. When I download the Compact Flash cards and import to Lightroom, I am reminded of just how slow they are. I used to do this all the time but, once I started using CFast, I got used to the better speed and now, when I revert to the old tech, it feels positively glacial!
Not being able to go anywhere means you can only photograph things close to home. Why not dig out the macro lens. I have no doubt that many photographers have been doing the same thing when stuck at home too. I initially didn’t have any obvious plan for this. I just decided to photograph anything around me to see what it looked like when seen up very close. Textures on the surface become apparent in a way that aren’t normally. I also discovered just how much dust on on somethings that I never noticed until looking at the images.
This is a tale of a problem I got in to with Lightroom. I Googled solutions for this and got a bunch of suggestions but none of them worked. In the end, Adobe sorted out the issue but I wanted to share what happened in case anyone else experiences the same issue and ends up Googling like I did. Maybe this post will help someone out. The source of the problem was an MP4 video file that apparently had some corruption within it. This screwed up stuff within Lightroom that needed some detailed work to fix. First, I shall tell you what the main error was. This might be what someone is searching for.
Dynamic Link Media Server Failed to Launch
The result is that video files don’t import and then you seem to struggle to preview videos at all. When you are in the Import dialog, the video preview doesn’t show and an icon of a camera comes up instead. Some of the recommendations online were to delete the Dynamic Link Media folders in the App Data section of Windows and restart but that didn’t help. I also tried that and deleting the media cache but no luck. Next was to delete the Preferences folder for Lightroom which can often be a solution for unexplained problems but that didn’t work either. That is when I got Adobe involved.
The support engineer tried a bunch of things. Eventually, he created a new user on the machine and opened up Lightroom in there. We tried importing a new video file from the same camera and that worked. He then set about deleting the Lightroom related app data in my user profile and replacing it with the data from the new User. We then tried importing the new file and it worked fine. Next was the previous file and that caused the same problem as before. Now we knew the file was the problem we could isolate that from everything we did afterwards.
Of course, I had damaged Lightroom again but now we knew what was required, it was a simple task to copy the folders across again. The only downside to this was that all of my presets and information got deleted. However, I had copied the old Lightroom folders before starting all of this. It wasn’t too tricky to replace my camera profiles, develop presets and plugins. At first I thought I had lost some functionality that I really like. I have a plugin called LRInstagram which allows me to post from Lightroom to Instagram directly. Facebook has turned off the ability to do this so, if you install the plugin now, it won’t work. However, something about my legacy setup meant I had still been using it. When I tried to set this up again, it failed to work. However, my old Lightroom folder had a sub folder for the plugin which contained something like a cookie and, when I copied this across, I was back up and running!
All of this is to say, if you have a similar problem to me, there is a solution. I won’t lay out the files that are involved because it is a bit tedious and there are some other things to bear in mind but, if this happens to you, get in touch and I will talk you through what we did.
A while back, I bought the Lightroom plugin, Negative Lab Pro. This is a plugin that converts digital images of negatives to a positive image. I wrote about it in this post. A short time ago, the developer brought out a version 2.0 upgrade to the plugin. It turns out, the upgrade was free for those of us that had bought the original plugin. I installed the upgrade to see how things have been improved.
Initially, I was very disappointed. The conversion process after the update seemed to be awful. Things looked dark and blotchy and efforts to unconvert and reconvert the images didn’t help. I was perplexed by this since a number of users had already exclaimed how happy they were with the update. If in doubt, follow the old approach of closing stuff and restarting it. I closed Lightroom and reopened it and whatever was wrong before was now fixed. The conversion worked very well. The controls have been expanded to give you a bit more to play with. The main benefit I am seeing so far is in the color balancing. Shots seem to have a more natural look to them without me having to work too hard on the color in the first place. Shots like those with a lot of sky and an odd colored aircraft will still test the algorithm a lot but otherwise it seems to have a good handle on things. It is also now able to handle frame edges without getting confused. You can tell it how much of the edge to ignore which is a useful feature although I have got into the habit of cropping carefully already.
All in all, the upgrade seems to be a good one. Since it hasn’t cost me anything, that is a nice thing to have. It is also good to know that the developer is continuing to work on the product which holds out the hope of further upgrades to come. I continue to recommend this to anyone that has been scanning their old negatives with a digital camera.
I was downloading shots from two cards into Lightroom when one of the downloads seemed to hang. I have seen this before and on those occasions, removing the card and starting again did the trick. This time it didn’t and, when I reinserted the card, the computer said I needed to reformat it. I thought I would try it back in the camera to see if that was okay but no joy. Time for RescuePro Deluxe again. I wrote about using this previously. I had an issue with it one time when I tried a recovery and the same thing happened this time. The card drive letter doesn’t show up (nor do any of the others).
There is a simple fix to see them all which is to press the H key. However, I hadn’t made a note of that previously and couldn’t remember. Fortunately, their help desk gave me the code and the pictures were all swiftly recovered. (I jest. The program works well but recovering everything it can find on a 64Gb card and then working through that to find the files you really want rather than something from months previously is a bit of a slow process. Still, it is a lot better than the alternative of having no shots!)
In previous posts I have described my efforts at scanning old negatives using a digital camera, macro lens and a light table. I have had mixed success with the process for converting the negatives into positives with some films responding better than others. I was okay with the output but thought things could be better. A YouTube video showed up on my page that was about scanning negatives with a digital camera and I decided to watch to see if they did anything different to me. The technique for shooting the negatives was similar enough but they introduced me to a Lightroom plugin called Negative Lab Pro.
I downloaded a trial of the software and gave it a go. I was sufficiently impressed with the output that I stumped up the cash for the full version. It isn’t cheap but, given that I can now use it on several thousand images, I figured it was worth the investment. The plugin requires a small amount of effort. I revert the images back to a normal San without any of my previous edits and conversions. The first thing to do after that is to take a white balance reading from some of the visible edge of the film to neutralize any color shift. Then you crop in on the image. Apparently, it is important to avoid getting any unexposed edges in shot as this messes with the algorithm.
Then you open up the dialog box. It analyses the image and does a conversion. You then get some basic sliders to tweak the settings such as exposure and color balance. There are some auto setting check boxes but I haven’t found them to be too helpful so far. Then you click okay and the image is ready to do further editing in Lightroom. You can also do batch conversions of images if you want although I think it is probably better to focus on individual processing. I have been playing with this on a range of images so far and I like the results. My old negatives are not that great and this is not going to suddenly make them amazing but I am impressed how much more I can get out of some of the scans using this software.
Updates to Lightroom come along relatively regularly and they tend to include new features along with fixes and performance tweaks. The latest update, Lightroom 8.2, includes a new addition called Detail Enhancer. This is a feature that is designed to provide some better small-scale detail as part of the raw conversion process. It creates a new DNG file based on a more complex calculation of the demosaicing of the sensor data.
I saw some videos about it and figured it wasn’t going to be of much use for the type of thing I am working on. However, it did trigger one possible area of interest. The algorithms are supposed to be designed to make better calculations around the different color pixels that sensors have. Sensors are set up in a Bayer Pattern where different color sensitive sensors occupy different pixel spaces. They each record in one color and then software interpolates between them to create colors for each pixel irrespective of which color was originally recorded at that location.
In a post from a while back, I mused on the way in which the colors of the Southwest Livery and the registration clashed and seemed to provide a distorted image even when everything around them was sharp. I was pondering whether this was artifacting caused by the different colors and the way the sensor was recording the data. If this was the case, maybe this new functionality would change the way things were rendered. I dug out a few of the shots that had previously demonstrated this effect and ran the process on them. These shots show the wide shot, the original rendering of the close up and the revised rendering using Detail Enhancer.
As you can see from the comparisons, Detail Enhancer does not suddenly render a perfect registration for the aircraft. However, to my eye at least, it does appear as if the results are noticeably better then they were with the original rendering. For completeness, the original rendering is done with the latest process version of Adobe’s raw converter to make things as fair as possible. It does appear to make a difference. This makes me think my theory about whiny things looked wrong might have some merit, even if this update has not fully resolved things.
