29 Mar 17 A very few of you have seen this before, but most of you haven't. I'm sorta picking up where I left off on Monday. You recall I mentioned shooting the moon rising over the city twice a year, from West Seattle in January and from Kerry Park in June. This is the image you used to be able to get from Kerry Park but no longer can for at least three reasons which are the trees are 10 years taller and block some of this view, the city now "encourages" the building owners NOT to light their buildings, and the amusement park has been torn down. I'll spare you my rant of why the last two items happened. But now this capture is a thing of the past. Of course you can still shoot from Kerry Park and capture the moon, but it will never be this view again!! When we still lived in the city I used to go to the park 4 days in succession to capture the moonrise each night as the time of the rise was always later each day which makes for different effects light-wise and it moves from left to right across the city by a substantial amount each day. Thus the captures were very different on each visit. After having shared these photos in a couple of clubs I began to be asked to lead groups to do the shoots. Like I did for the shoots from West Seattle, I always had them arrive very early in order to get a spot to stand before it got to be shoulder to shoulder and also to spend time with each photographer to explain what they needed to do and how to do it to get the shot. This image is a composite of two frames taken a couple of seconds apart at most; the aperture was kept constant but the shutter speed varied by 10 -12 stops of shutter speed depending on the height of the moon. The timing was necessary to keep the moon in the almost exact spot and the shutter speeds to get the proper exposure. As the light from the moon is roughly 1000 x brighter than the glow from the lit buildings, two different exposures are needed, one for each, to keep both the moon and the city equally balanced light wise. Then you put the two captures together using the moon from its exposed frame to fill the hole in the cityscape frame caused by the blown out moon. The result is a city with the moon rising behind it with both balanced light wise. You cannot do this in a single frame, at least not yet, although we are not far from having cameras, such as the Nikon D5 and D500, that come very close. In all likelihood the next generation will be able to do it. This was taken in 2007 when cameras couldn't come close.
Two frames have been combined to get the shot. Other than slight temperature adjustment, and a little straightening, these are straight from the camera shots. Nikon D200; 18 - 200; Aperture Priority; ISO 400; 4 sec & 1/250 sec @ f / 7.1.
