Back from ISAP

Another year’s ISAP symposium has drawn to a close and we have all headed home (or straight off to other assignments for some!). This was a good year overall and I had a lot of fun. Having been to a number of them over the years I have built up a number of friends that it is good to see as well as enjoying the content of the presentations. Not everyone was there this year and I missed the presence of a few people but, hopefully, they will be back at the next event.

I saw a lot of fun things and got some shots so expect to see a few more posts in the coming days that show some of what we saw.

Glorious Cheating!

The moon was supposed to be at its biggest recently. I was all ready to head down to the lakefront and get some shots as it rose and the atmosphere magnified it to the greatest extent possible. However, as the afternoon started to wind down, the fog started to roll in. As the sun was setting, the fog banks were wafting between the buildings around us and you couldn’t see the harbor wall let alone the horizon. Oh well, what can you do?

As the evening rolled on, the fog finally cleared out but, by then, it was too late. The moon did appear amongst some of the buildings so, while it didn’t look significantly different to normal, I still decided to get a couple of shots. The problem with this is that the moon is effectively in sunlight while the city is in night. The top picture is the cheat that resulted. Below are the two shots I took next to each other. One was exposed for the buildings and the other was for the moon. A bit of layering and masking in Photoshop was necessary to get the result at the top. I am not a Photoshop wizard and I suspect those that know their stuff would tell me why it is not as well executed as it could be but this was hardly a client job! Just a bit of fun.

ISAP Here I Come

It is that time of year again when ISAP members get together to share knowledge, learn knew things, see what each other have been up to and generally have a lot of fun. Throw in some chances to shoot some great airplanes and you have a great time. I can hardly wait. Hopefully more to report from the trip. We even have an air show tucked in at the end of the weekend so it should be fun.

You shall find out more when it happens – or a little while afterwards… Blogging might be a bit sporadic while I am gone.

Lightning Up the Mood

Leave a Reply

A little night shooting today and a confession about my role in what was going on. We moved to Chicago eight years ago. When we first got here, we were amazed by the storms we got. There seemed to be lots of them and they were really pretty spectacular. When looking out of the window we would see lightning all the time. Sometimes the storms went on for so long it was hard to believe that it was a storm and not someone planting an emergency vehicle outside the window – a neat trick at the height of our place!

Strangely, for the last few years, we have had very few storms. They seem to miss the city and go either north or south of us. Some people are getting a lot of them but not us. This was a bit disappointing to me because I love storms! They are so dramatic and very cool. They are, of course, rather destructive but watching them is exciting. This week we got a good storm. The sky was alive and it was a lot of fun. It was also rather late and I needed to go to bed. Consequently, I cheated.

My 17-40mm lens is not enough to cover the full view south of us so I went with the fish-eye zoom instead. I set the camera up on the tripod, added the intervalometer and basically set it on its way. The gap between the shutter closing and the trigger for the next shot was just long enough to allow the file to write out. Then I went to bed. The result is a LOT of pictures with almost all of them of no use. However, it did capture a couple of shots that I really like. I even tried using the new lens correction facility in Photoshop CS6. Our view is a little less impressive since the Trump Tower blocked a big chunk of the skyline but it still gives a nice look to the storm. Hope you like them too.

Lots of Work Down the Drain

No pictures in this piece and that is kind of the point. I have been working for a long time on setting up a photo shoot. The plan was to get some pretty unique shots of a rare jet that is owned buy a great guy I have worked with for a long time. The plan was to charter a camera ship that allowed some options to get shots that are harder to get normally. I had found an operator of the right aircraft that was in the right place and was happy to do the job.

We had the pricing agreed and they had even sent me the draft lease documents. I had made some amendments to these and sent them back to be finalized and then suddenly everything goes quiet. I send a follow up and hear nothing for a while. Then I send another email and the response I get is not good. They have found a more lucrative job and I am no longer on their schedule! How about that? You spend time briefing what is required, discussing all of the details, agreeing the pricing and you think that you have it all agreed. You are finalizing a lease document which includes a down payment so you think they are serious. Then you are dropped like a stone.

I think it is fair to say I am really pissed off. I am not going to name names because that isn’t going to help and one day I might need them for something else so I will keep the details out of this. However, I try to always be professional in the way I deal with people whatever part of my work is involved. I guess not everyone shares that approach. If they found a better job, perhaps they might have tried to solve my problem as well. They gave me a name for an alternative but this short a notice period is unsurprisingly meaning that an alternative is not available. The other guys tried hard to come up with a suggestion and I am grateful to them for that.

Having ranted I shall now wrap up. I was really hoping that you would see here the great results of what had been planned but I shall have to say instead that it just didn’t happen. Now to see if there is something we can come up with instead.

Skating Action

Leave a Reply

Some time last year I wrote a blog post about photographing some guys jumping bikes in a park here in Chicago. If you want to check that out, this is the post. I had been inspired by a great book by Syl Arena on flash photography and what can be achieved to freeze fast action and to add drama to the shots. This has also got me interested in trying another sport, skating (the skateboard variety, not ice). They are a couple of skate parks along Lakeshore Drive in Chicago, one north of us and one south. I had never before managed to time it right to get to one of them but finally I have done it.

I got the park and a few people were skating around. I watched for a while to see who was a more comfortable skater before asking whether anyone would let me take their picture. One guy, Konrad, was kind of okay with the idea but seemed a bit skeptical. Most other people were not keen. Konrad had one location he had been making some good moves on so we set up there. We grabbed a few shots from different angles with me mainly using a single light triggered by cable rather than IR. This is tough stuff to do so you can’t just have them do it over again until you are happy. They get worn out.

We grabbed a few shots and then Konrad went off to skate some other parts of the park. When I got back, the shots were not too bad. The use of a single light was not ideal as, with the deck in front you get quite a shadow cast. Also, it reflected strongly which tended to limit the light on him. Two lights will definitely be better. Fortunately, a little work in Lightroom managed to enhance the balance on him a bit. A first time out and not too bad. Plenty to improve on next time though.

Trying and Failing with Bad Weather

Leave a Reply

Every once in a while you have what you think will be a good idea and it turns out you were wrong. This is the story of one such event. A weekend morning was looming and I felt like getting out and shooting. The flights from Asia are morning arrivals at O’Hare and so are not often something I shoot. A few of them appear and that is it. Back to the RJs and 737s so I often don’t bother. Also, the normal arrival pattern is not great for morning light.

This time they were coming in from the west so heading in to the light. However, the weather forecast was a bit crummy. The traditional thought is not to go since dull skies and mainly white planes are not a great combination. However, two things made me think otherwise. One was the possibility of the sun breaking through and illuminating the aircraft against a dark sky background. That can look good. The other was the possibility of a lot of vapor in the air making for some neat vortex effects and vapor clouds over the wings.

Consequently, I decided to give it a go. I headed out having scoped out a potential location to shoot from that would give me a view of the arriving aircraft. I have not shot over that side much before so a good location is not something I had. There is a lot of industrial space over there so buildings can obscure the view and the ever present power lines are another consideration. As it turned out, the spot I chose turned out to be quite reasonable.

That is where the rest of the plan starts to go wrong. The sun did make a brief appearance. The opening shot is probably the only one that really achieved what I was hoping for. After that, the cloud cover thickened up and then the skies were pretty unhelpful. My second hope for the moisture to give some good effects proved to be a little too optimistic. There certainly were plenty of trailing vortices and occasional puffs of cloud above the wings but the gray background did not help make them stand out.

I decided that I was probably done for the day and started to drive south on my way home. I then happened upon a few cars parked up at a spot directly under the approach to 14R. I thought this might be worth a look and it certainly made for some good angles. I grabbed a few shots before heading home but this was a spot I decided was worth a further visit. More to come on that…

Lightroom 4 Impressions

Leave a Reply

It is a little while now since I upgraded to Lightroom 4 from the previous version (I will let you fill in the name here!). There were a few aspects of the new version that made me want to upgrade and I had played with the public beta version when it first came out. Of course, having ongoing support and updates is always helpful so staying with the old version was never going to be likely and when they halved the price, no further thought was required.

Now I have been using it for a while, what do I think? Well, on the whole I am reasonably pleased with the changes. The new sliders in the Develop module seem to be an improvement on the previous develop version. I was pretty happy with the way it worked before so the changes had to sell themselves to me. They have modified the way I think about the development settings since I used to be able to use Exposure alone to bring back a sky and maintain the shadows. Now I have to consider the White and Highlight sliders a lot more. I am not convinced that Highlight does a lot. White seems to be far more effective in my new approach. Similarly the shadows slider is now more important to me than the blacks which is a change.

Another issue is with converting previous develop settings. Since the change of sliders is significant, going to the new develop version tends to result in all sliders being reset to zero. This can turn a reasonable image into something far worse initially. Lightroom does not have a conversion algorithm to get you somewhere close. It is back to the beginning. Maybe this makes a lot more sense.

The Map capability is a big improvement for me. Canon cameras are not well designed for adding a geotagging capability so I have ignored it on the whole or experimented with Jeffrey Friedl’s plugin. This is a very user friendly method and I shall make use of it a lot more I think. I like the book creation capability but would welcome some other outlets getting in the game. I have used Blurb before and they are fine but I have liked Adoramapix and have contacted them to see if they will be making templates soon. Let’s hope so.

So, is there anything wrong? Oh yes! It is slow!! The Develop module is awful at the moment. I have a pretty capable system but the sliders we very slow to react. The real time view of what you are changing is not there yet. You pick a slider, hope that the mouse click has actually selected it and then move to where you think works and then wait to see what happens. Is this acceptable? Not at all. Am I annoyed? Yes I am. Is it the end of the world? Probably not. I seem to recall that Lightroom 3 had similar issues when it first came out and was slow. Adobe released some updates pretty quickly and it ended up being a great tool. I am not going to revert back and will manage the sluggishness until they come up with a fix. If they don’t, I may have to consider but I am not the only one having an issue so I suspect it will be dealt with in the coming weeks. Turning off the second screen makes a substantial difference but is not very useful so hopefully that will be tweaked. A release candidate for version 4.1 is out now so, while I won’t try it out, hopefully that means the formal release is pretty close.

One other thing I will tag on her and that is the arrival of the beta version of Photoshop CS6. When the beta was released, I was not sure I would bother to try it out just yet. Photoshop is still part of my workflow but, as Lightroom has become more capable, Photoshop has been used less often and for more specialized tasks. I could probably wait, or so I thought. However, I watched some of the demonstrations of new features online and liked some of what I saw, especially the video editing. Since I shoot mo video these days, having an alternative video editor rather than upgrading the package I have might be good. It does seem to have some good basic capabilities and that is all I do most of the time. What isn’t there at the moment is good bio integration with Lightroom. Version 4 has some video clip editing for end points. It would be good if you could send the video to Photoshop in the same way you can an image. Since it would then come back to the catalog when you had finished, it would help in managing everything. Now I finish an edit and I have to import it – if I remember. If they could allow you to take multiple clips and open them as layers (again like you can with images), that would be even better since that lines up with the way video editing is set up in Photoshop. I commented on this on the Lightroom blog but we shall see if they are already working on this.

In conclusion, I am pretty happy with the new Lightroom. With the price halved I am even happier not least because the Photoshop upgrade is obviously not far away. Now to see whether they can tweak it enough to fix the minor problems.

Changed Workflow

Leave a Reply

I have changed my approach to editing my pictures quite a bit recently. This has served two purposes. The first is to make better use of my storage requirements and the second is to focus more quickly on the better images. Sadly, this has highlighted to me how I have actually missed out on some of my better work in days gone by. Not a happy lesson to learn but a valuable one.

I never used to delete images since storage was not a problem. I did occasionally find images that newer RAW processors could do something with. However, to be honest that was a rare occasion and, even then, I wasn’t likely to have an outlet for that image. However, by not getting rid of stuff, I really cluttered up what I had. Moreover, I would scan through and find images I liked the look of and mark them as favorites. When I would come back to them later, I would find they were a bit flawed – not sharp enough usually being the problem. What was worse was that I would search based on ratings and so wouldn’t bring up the next shot which actually might have been almost identical but sharper!

Consequently, I had a workflow that hid the good shots and encouraged me to pick the wrong examples by mistake. I have now changed all of this. Part of this is driven by trying to keep storage requirements under control. I have been shooting a lot of rotor-craft and getting good rotor blur requires low shutter speeds which often means shooting lots of frames to get a few sharp ones. When you are being buffeted by the down-wash, no amount of good technique is going to be enough! I do generally shoot more these days anyway so I have a lot to work through.

The first thing after downloading is to generate 100% previews of all images. I can then set up Lightroom with one side as the full image and the other has the 100% view. This way I can determine sharpness of the shot at the same time as seeing whether the overall image is okay, i.e. no poles across the shot or noses cut off! I have copied a process I saw demonstrated online where I assign a job descriptor in Lightroom and then set up smart collections for that job of Picks, Not Rejects and Rejects. I have also started separating out video clips to another smart collection. By reviewing the Not Rejects folder, anything rejected gets automatically removed so it thins out as I go.

This certainly brings the numbers down but not always as dramatically as I would like. I suppose I should be pleased that I am not shooting such a low percentage! Once I have done this, I can now trust that the shots that are left are all considered usable. Then I can go through again and weed out the obvious duplicates by picking the best of a given type. This will really help to thin things out. The other thing I will do (which I also tend to start as I get further through the first review) is culling those that are just not interesting. I have come to the realization, far too late, that only the best shots are ever going to see a use somewhere (and most of them won’t either). Therefore, a relatively uninteresting shot that is sharp and well composed might as well go in the trash unless it has something unique about it. Most don’t!

This has resulted in me thinning down the shoot far more rapidly. The review also includes marking as Picks those I particularly like. Hopefully, this will make it a lot simpler to get to the good stuff in due course. Now I am also gradually following the same process for the large selection of previous images. Maybe I won’t have to upgrade my hard drives for quite a while with all of this space I am freeing up and the reduced rate at which I am filling space.

One footnote to all of this. My NAS runs a backup of everything every night. When images get deleted, they will be gone from the backup the following night. However, before anything is deleted, it is all backed up to Blu Ray discs. That way, nothing is truly gone forever. However, it would require some serious effort to go back to those discs to find something that is deleted since they are gone from the Lightroom catalog. However, they are easy to backup so why not?

Final Overnight Time Lapse

Leave a Reply

I mentioned before that I had tried to do an overnight time lapse video. In that post I detailed all of the ways I had screwed up the process. Rather than sulk, I did take all of those lessons to heart and went back for a second attempt. This time, I was a lot more successful. I hadn’t got around to figuring out how to make the tethering work properly but the alternative was acceptable and I had learned the rest of my lessons.

One minor hurdle still existed. Our windows are not at their cleanest at this time of year and shooting through the glass is the only option. We are due to have the cleaners take care of them shortly (although that will probably only guarantee some rain immediately afterwards). In low light and with a wide enough aperture, the dirt smudges are not too much of a problem. I have to make sure the shoot doesn’t include any time with direct light on the window which would make the muck flare up in the shots.

The other minor issue is a function of the double glazing. More intense light can show up the effect of the light bouncing between the glass panes. At night this isn’t a hassle except with the moon which is so bright. For some reason I should be able to figure out but can’t, the center of the window almost totally removes this effect and it gets worse towards the edges. However, the moon is so bright in the scenes it blows out and, since the whole thing animates to a video, the loss of shape in the shots becomes less apparent as the moon zips across the sky.

With all of that said, here is the video itself. It seems to have worked out well. Sadly, the messed up effort seemed to have got some more interesting light sequences from the windows of the building but you can’t have it all. Enjoy!
