I was taking some shots for work recently where the sky had some nice cloud detail and the foreground was in a lot of shade. Since the pictures were needed for a project, I was covering my bases and shot some brackets to allow me to do some processing in HDR later. Some people hate HDR but I have always been looking to use it to get a shot that reflects more the human eye’s ability to deal with extremes of contrast. With a wide range of light levels in a shot, HDR can give you a more usable image.
However, when I was processing the shots, I was struck by how I could use the middle exposure alone and, with some helpful adjustment of exposure, shadows and highlights, I was able to get much the same sort of result as the HDR image provided. The raw files seem to have enough latitude for processing that going to the bother of taking and processing the HDR image hardly seemed worth it. There are still situations where the range of exposure is so wide – outdoor sunlight and shady interiors – that it is still probably necessary to bracket and process later. However, for a lot of the situations I used to use HDR for, there seems little point. How many of you still shoot HDR?
Adobe periodically updates the processing algorithms that are used by Lightroom and Photoshop. Each update provides some improvements in how raw files are processed and it can be good to go back to older shots and to see how the newer process versions handle the images. I find this particularly useful for images shot in low light and with high ISO.
I have some standard process settings I use but have also experimented with modified settings for use with high ISOs and the higher noise levels that come with them. I got to some night launch shots from an old Red Flag exercise and had a play with the images. The E-3 launch was actually as the light was going down but it still had some illumination so it didn’t need much work.
The KC-135 and B-1B shots were a different story and were at high ISOs and with very little light. I was able to update the process version and apply some new settings I had worked out since the original processing and it resulted in some pretty reasonable outputs considering how little light there was to work with.
With the ferries coming and going to the terminal at Orcas, I was able to have plenty of chances to take photos. I did get standard shots of the boats in low light conditions. They are not easy to shoot since they are constantly moving. No long exposures at low ISOs are possible so it is high ISO and the associated noise. However, I did decide to experiment with some long exposures and blending of shots. The boats make a curving approach to the terminal. I thought this might make a nice long exposure. It worked okay but the curve is a bit disguised by being too low down to really appreciate it. However, it was fun to try.
Winter in the PNW does not mean reliable conditions for photographing planes. If the weather is bad, you might decide it isn’t worth going out. If it is raining and threatening to rain harder, there is a strong possibility you would skip a shot opportunity. However, 727s are getting pretty rare these days so that seems worthy of a trip out.
The weather was unpleasant when it made its approach but not as bad as it got a short while later. I went with my normal approach for shooting in really bad conditions by pushing the overexposure pretty high. I include a couple of edits. For the main image, I actually blended two different process versions in Photoshop to get the combination that most reflects how the shot looked through the view finder. The other edit is a straightforward Lightroom edit where the angle and the light suited it.
I’m sure a bunch of my relatives will look away for this post. Maybe they aren’t fans of focus stacking but it could be the spiders that put them off. My macro lens has been out a lot during the pandemic since it provides something to photograph close at home that is a bit different. In fact, I have got so used to having it available, when I am out with a normal lens and come across something small and interesting, I am a bit frustrated to realize I can’t get a close up shot.
The problem with the lens is that it is not a very advanced one and the autofocus on it is pretty crap. When I am trying to hand hold the lens and something is moving and so am I, things get a little unpredictable. We had a few spider webs in the backyard with the owners sitting in the middle. The afternoon sun provided great illumination so I figured I should give it a go. I tend to go to manual focus and move to get the shot but with the breeze moving the web a lot, things are pretty tricky. This is what prompted me to try cheating.
I figured that focus stacking does a good job of increasing the area in focus and it manages to align images and make use of what is already in focus. If I can be straight on to the spider and stay reasonably still and roughly at the right focus point, let the web move towards and away from me and fire a bunch of shots off hand held. Ignore the ones that have nothing in focus and then let Photoshop work on the remainder.
It isn’t a perfect solution and some weird things happen at the edges of the frame but the center works out pretty well and you can crop in a little to address the edges. I was quite pleased with the outcome to be honest. It is making the best of a few bad elements but it did do quite well. You don’t get to control what is in focus for each shot so getting a complete set to work with is unlikely but overall, not a bad experiment.
Summer weather means lots of sunny days but also means lots of heat haze. I was at Boeing Field one sunny afternoon and there were two jets parked across the field that I wanted shots of – one was an Illinois ANG KC-135R and the other was a Falcon 20. Looking through the viewfinder, both of the were shimmering in the heat haze that a warm and reasonably humid day brings. This is the downside of summer in the Pacific Northwest.
Not long before I had watched a video on YouTube about photographing Saturn through a telescope. The image of Saturn was all over the shop but they were using a software technique to take multiple images and build a more stable and sharper final image. It worked reasonably well and this got me thinking about how to do something similar. In the past I have used Photoshop to blend together multiple images to remove the moving elements of a shot like people or traffic. I wrote about it in this post.
I thought I would see if something similar could be done. I put the frame rate on to high and steadied myself before firing off a few seconds of shots. I wanted a lot of images to provide the best opportunity for the statistical analysis to find the right solution. Importing this in to Photoshop as layers and then auto aligning them allowed the analysis tool to do its thing. I don’t think the result is quite what I want and I may experiment with different analysis methods – median versus mean for example – to see which ones are most effective. However, there is clearly a smoothing out of the distortion and, if I needed to get a shot on a hazy day when there wouldn’t be another chance, I would definitely fall back on this approach to see whether it produced something more usable.
While scanning through some images, one of the shots that showed up in my catalog was an HDR processing of some shots of a US Army Chinook. It had been processed with a plugin that I had previously experimented with. I thought it looked over vibrant but I was impressed with the way the dark interior of the helicopter had shown up while the outside was also well lit. I decided to have another go at processing the images.
I used Lightroom initially to do the processing. It came out surprisingly well and looked not unlike the outcome from the plugin. However, there was some ghosting on people in the shot and there was a lot of chromatic aberration. I have noticed issues with Lightroom making a worse job of it than Photoshop so I decided to try HDR Pro in Photoshop as well and use Camera Raw for tone mapping. The outcome was very similar from an overall perspective. However, the ghosting was virtually eliminated and the aberration was not apparent either. It clearly is still a better bet than Lightroom.
After four months of no hair cut, I finally managed to get some clippers and set about cleaning up my head. I won’t share the awful look that I had developed (and the current look might not be that great either) but I did have Nancy take some pictures before and after. While she was taking the after shots, I asked her to take a couple that were directly head on. I was interested in facial symmetry.
I had seen articles in the past about how some people have quite symmetric faces while others didn’t and I had been meaning to try this out for myself. I got a shot that was nice and head on so took it in to Photoshop. There I duplicated the layer and flipped it horizontally. Aligning it centrally was a bit of a choice because you can move it around a little and just widen or narrow the face. I got it to a place that seemed about right. The fact my face is asymmetric means that there isn’t an exact center to align against.
I then added a layer mask to two versions of the image to blank one side or the other out. The result is two versions of my face using either the left or the right side. The difference between them is quite stark. My jaw is slightly lopsided as is my nose and so one version has a far broader look to it while the other is a lot thinner. It’s like two different people.
I was recently watching a video of a landscape photographer and he took a trip to the Hoh Rain Forest on the Olympic Peninsula in Washington. Nancy and I went there on a vacation a few years ago and I posted about it here. I decided to go back and look at some of the images from that visit and see what I liked. I had taken a bunch of photos in multiple locations on that trip and I found that I had not really given many of the shots any effort.
I decided to take a look at both those that I shared in the original post but also some “new” ones. I realized that a little effort made the images so much more interesting. The rain forest is so lush and there is so much green that it almost seems unnatural. I brought down the exposures a bit and did punch of the saturation a little. It does look a little overdone but I assure you it is actually a reflection of what the place is really like. I think digital cameras tend to tone down greens a bit and, when the place you are looking at is all green, this is a bit of a problem that needs to be addressed.
Oho is about four hours drive from where we are now. A bit of a trek for a day out but I think a trip over to that side of the peninsula is definitely something we should do again before too long. We can also check out the coastline over there which is really stunning.
I was at the Museum of Flight for the IPMS exhibit but, while I was visiting, I figured it would be churlish not to take a picture of the M-21 that dominates the main hall. It is actually a bit difficult to photograph and there is a lot of contrast with the background and it is always busy so a bit cluttered. I knew it wasn’t going to be a great shot but decided to crop tighter on the airframe and shoot bracketed exposures and maybe go with an HDR process. It isn’t great but it came out better than I had expected.
