Variable Neutral Density Filter

Two of my shooting requirements have led me to the world of neutral density filters. Getting a low shutter speed on helicopters often results in very small apertures which can be a pain when it comes to sensor dust. Also, when I am shooting video I also want to be able to slow down the shutter speed. This can sometimes be hard to do and again shows up the sensor dust if it is there and dealing with it on video is a bit more effort.

Consequently, I decided to try out a variable neutral density filter. There are plenty on the market but I decided to go cheap! Why not? I never spend too much cash on photographic equipment!! This was from Amazon and was only about $40 so I wasn’t going to lose sleep if it turned out to be a bust. When the time came available, I decided to do some testing. I shot a clear sky with the filter set to varying levels of light reduction. I then imported these images into Lightroom to see how they looked. The answer was not good. In the mid range, things were actually reasonable. At the low and high ends, there was a significant variation in brightness across the image. This was not going to work.

I then decided to keep things simple. I already have a filter holding system for my old Cokin filters. I decided to buy a couple of neutral density filters for this. Then I can use either of them or both if the circumstances require. Not quite as flexible as a variable filter but pretty close and certainly more reliable without going to the expense of one of the top of the line variable models. We shall see how I get on.

Working Bell 407

Leave a Reply

I was heading back to the airport in Tucson to catch my flight when I came upon a Bell 407 doing some long line work with a person on the end of the line. Normally this sort of thing happens when you are nowhere close to a convenient place to stop. However, this time I was in luck. A turning was coming up and it had a great place off the road to stop. Consequently, I got to spend a bit of time watching the team training.

They were from the Arizona Department of Public Safety. I have no idea what that is and as a dodgy foreigner, I wasn’t going to ask. They were lifting a guy from the ground, holding him for a while and then depositing him back on the ground. They also landed briefly during the time I was there. I did have a flight to catch so I couldn’t hang around for too long but I was able to get a few shots of them at work before it was time to take the car back.

Since they weren’t too far away, I was able to use the 70-200mm. That also gave me some flexibility for playing with low shutter speeds. As I do in these cases when I have the time, I ramp the speed lower and lower. That way I figure I will get some sharp ones and then gradually increase the failure rate until nothing comes out sharp or, as is the case on a sunny day in the Arizona summer, I run out of apertures to slow the shutter speed any further. In this case, I had good luck throughout the range and was able to get some really nice discs for the rotors.

Roll Out the Barrel

Nancy and I were up in Healdsburg as part of a weekend away. She wanted to check out a winery called Ferrari-Carano while we were up there so we headed off to find it. It turned out to be a very attractive location. The buildings were beautifully designed and the grounds had been expertly landscaped. Even if you didn’t want any wine, it was a nice place to walk around for a while.

We were interested in the wine too so went in to buy some of their stock. I took a wander down to the basement where you could see a healthy selection of barrels of wine being stored. Sadly, this area was off limits so I had to be content with looking through the glass at the stockpiles. There was enough wine down there to keep me happy for a while. It would be fun to have a closer look around. Maybe they have tours that we can go back for. If not, at least we can buy more of their excellent wines!

Hawaiian Airbus and Friends

While waiting to get the shot of the Janet flight I posted about previously, there were plenty of other departures from McCarran. The majority of flights were coming out on the westerly runway rather than the one the Janets use so we were not getting the nice topside view of them turning. However, the light was very nice and so a few of them provided interesting targets. The Hawaiian Airbus A330 looked particularly nice but most looked good on those conditions. We were a bit focused on finding out how the Janet was doing so didn’t give them our full attention but some looked too good to ignore.

Egret

Nothing terribly complex about this post. I was out shooting when an egret flew by right in front of me. I saw it early enough to get ready and grabbed a few shots as it came by. Here they are!

Janets

The shuttle of flights run out of McCarran Airport, Las Vegas by private contractors for various departments of the US Government are known as the Janets. Previously operated using Boeing 737-200s, the flights have now been upgraded to 737-600s, probably as a result of the low price of these jets given their lack of popularity with airlines. They operate a pretty busy schedule at certain times of day. The flights file a plan to a location and then cancel it en route as they divert to whatever secret installation that is their true destination. Paul, Chris and I decided to try and find a good location to catch one as it departs since they make a tight turn out and should have good light in the evening. Several arrived while we were there and we were too late for one of the departures but we did catch one of them heading out. The light ended up being very favorable.

Marine Week

En route from a day with a client to the airport I had a spare hour to pay a visit to Boeing Field in Seattle. I figured that my time window would mean there was nothing much to see and I didn’t have anything longer than the 24-105 with me anyway. However, when I got there I could see an interesting collection of USMC machines on the opposite side of the field and the Blue Angels were parked up near the Museum of Flight.

I took a ride around to where the Marine helicopters and V-22 were parked and got chatting to one of the crews. He explained it was the start of Marine Week and offered a chance to walk around the ramp with one of the crew. I was not going to refuse that. Mario kindly showed me around and let me shoot anything external. They had three UH-1Y Venoms and three AH-1Z Cobras along with a single V-22. One fof the Cobras was marked up in special squadron colors. I took a walk around all of them and grabbed a few shots while chatting with Mario about what it was like to support these machines. He had worked on the UH-1N before converting to the Venom so he had some interesting perspectives on the relative reliability of the two.

These machines were going to be progressively moved across to the other side of the field as part of the public displays for Marine Week and the first of the Cobras actually was towed while I was there so my timing was excellent. However I did have to go and then my timing let me down as, while I was driving away, I saw an AV-8B Harrier II coming down the approach. Oh well. I still did better than I had expected.

Moonrise and Sunset

An evening flight out of SeaTac was my way home on a recent trip. We were due to take off after sunset so I hadn’t anticipated having the camera out. As we taxied out, the sunset looked pretty nice and I did get a couple of shots with the phone. However, there was a small moon also heading towards the horizon and I figured I should get out the real camera to make a better shot of it. The moon was just about to go down while the red of the sky still remained courtesy of the now-set sun. It was a bit of a dark shot and through the window of the 737 but it turned out pretty well.

Black Hawks at Mather

The California National Guard has a selection of Black Hawks that are based at Mather. Paul and I drove around to see them parked up. They seem to have varying configurations of the type on the ramp so I assume they have multiple roles that are assigned to the unit and the different configs to suit the roles. The fencing by the ramp was a little tricky for photography purposed and it was easier to get the Huey on display using the phone to get the pictures since it has such a small aperture, it isn’t affected by fencing. It looks like an interesting unit and possibly one that might be worth covering in the future.

Lone Bat

My evening outside in Nevada with Paul and Chris included some down time while we waited to see what would happen next. While we were hanging around, we spotted a bat fluttering around. Needless to say, we had not come prepared for night wildlife photography. However, I had the ISO ramped up and a long lens in my hands so, while the shutter speeds might have been a bit low, I figured I would have a go. The little fella was not terribly close so these are cropped quite heavily and even then he is a bit small but a couple of the shots give you the distinctive outline of a bat, even if he was fluttering so fast that freezing him was not going to be on the cards.
