Early Morning Breeze Departure

I’ve seen a couple of Breeze airliners, but they are not operating in our neck of the woods, so they are still a rarity for me. When one of the A220s came to Boeing Field on a charter for a sports team, I was hoping to catch it. They were due out early one morning, so I was able to go before heading to the office. This did mean that conditions were going to be rather restricted with the sun only just above the horizon (assuming clouds weren’t there as well) but this would actually suit me since I didn’t want the jet to be backlit.

Sports charters have a habit of not going even close to the time that they are scheduled so I wondered whether I would be able to get the takeoff before needing to leave. Imagine my surprise and delight when they called up pretty much on schedule. Soon the jet was crossing the runway for taxiway Bravo and then heading to the departure end. As they rolled and rotated, there was just enough light in the sky to make for some rather pleasant colors, and I was really pleased with how the shots came out. The actual light levels were very low, so I shot at high ISOs. The cameras do a remarkable job of this these days but there was still a bit of noise to deal with and the latest noise reduction algorithms in Lightroom dealt with that very effectively.

Wrong Lens for Night Photography

I had a trip that took me to Los Angeles and, while it wasn’t a photography trip, I did take a camera in case I had the chance to get some images. I took the 200-800 as my one lens since I didn’t know what my shooting options would be so wanted maximum flexibility. The only downside to this choice was that this is a slow lens with small maximum apertures. As it turned out, I got to my hotel at the airport in the evening and the roof terrace was open so I had a chance to get some shots of the planes arriving to the norther complex.

Having a slow lens when doing night photography is not the ideal plan. However, you work with what you have. Also, since I know the R3 can produce some good results at silly high ISOs, I figured I would see what I could get. Even at the the max ISO of 51200, the shutter speeds were very low. While I wasn’t always at the full extent of the lens, this was not going to make things easy. There were areas where the ambient light provided more illumination for the planes, but I still went with high frame rates to see if I could get a few sharp results.

Surprisingly, things worked out pretty well. There was definitely a very low hit rate but the fact that I was getting sharp shots at all was very pleasing. The Enhance AI noise reduction in Lightroom could then do its thing provided the shot was basically sharp to start with. This combination gave me results I was very happy with. If I were to be back at this spot another time, I would definitely bring other lenses along that would provide better light gathering capabilities. Even so, knowing that this can work was a pleasant surprise.

Experimenting With Enhance Levels in Lightroom

In one of the bigger updates of Lightroom and Photoshop, Adobe introduced the Enhance functions adding either resolution or noise reduction. The noise reduction has been very effective for some of the shots I have taken with very high ISO levels. I decided to edit a shot with varying levels of noise reduction to see how things look. Since I had a bunch of cheetah shots taken in low light, I figured that would be a good subject.

You can vary the noise reduction level from 1-100. I made five edits with one unchanged and the remainder at 25, 50, 75 and 100. I then layered them in to one file to show the comparison. The unchanged edit is on the right while the 100 noise reduction is one the left. I felt like my previous experience had been that a level around 50 was a good outcome for much of what I had shot. When I looked at these results, I again concluded that the middle level was the best compromise. The 100 was just too much and 75 looked like things were a bit smudged. You can judge what you think. I shall experiment with levels each time I use it but it does give me a good idea of what to start with.
