Initial Impressions of the RF 200-800

When Canon announced the RF 200-800 lens, I was mildly interested but not too bothered by it.  However, in an example of how easily a weak mind can be influenced, when I watched some reviews by those that had used the lens, I started to be more curious.  The focal length range was always of interest, but the aperture range had initially put me off.  The reviewers suggested that the excellent ISO performance of modern mirrorless cameras meant this wasn’t an issue.  Also, while not in anyway cheap, the lens was very well priced for the range it offered.

I went to my local shop and placed a deposit for one of the lenses.  This was many months ago.  After that, things got very quiet.  I was beginning to think that I would never see an actual lens.  Then I saw something on a Canon rumor site that said August was likely to be a time when a lot of lenses got delivered.  Whatever the blockage had been, there seemed to be some relief.  The last Tuesday of July (stuff seems to get delivered to stores on Tuesday I guess), I get a phone call telling me that my lens has arrived.  Hurrah!

After work, I headed down to pick it up.  I then headed down to the water in Kenmore – a short distance from the store – to give it a quick go.  I didn’t have a lot of time, but I got a quick feel for some of its quirks.  Initially I was a little unsettled.  The stabilization seemed very effective, but it did make tracking things that were moving slowly a bit jerky as if the stabilization didn’t believe that I actually wanted to be moving.  I worried that this would be an issue.  However, the images seemed to be rather sharp so maybe it knew what it was doing.

When I got home, I did spend a little time looking at the hummingbirds on the bushes.  The light was very low, which should be a problem for a lens with smaller apertures, but it seemed to work very well and the images were surprisingly sharp and clean.  I then took it to its first airshow.  Again, results were really very pleasing.  The 800mm reach was so helpful since the show line was quite distant and I was veery happy with the framing I could get.  The jumpiness in the viewfinder is still something I find rather distracting but it doesn’t seem to be an issue for the images, so I guess the stabilization knows what it is doing.  I also shot some video at 800mm handheld and, while there was initial wobbling, there comes a moment when it seems to get what is going on and then it is rock steady.  Quite bizarre.  I think this lens could be a key part of my shooting going forward.  We shall see as my experience grows with it.

Night Shoot at Pima

One of the special parts of the trip to Arizona was that Mark and I got invited along by our friend Joe to a night shoot at the Pima Air and Space Museum.  I had seen some images from previous night shoots and the idea of photographing the many interesting airframes there in the dark intrigued me.  The museum is excellent and well worth a visit, but it can be hotter than hell there and the light can be quite harsh, so this was a great alternative to try.

When I was a student, I used to do quite a lot of night photography.  In the days of film, you played a lot more of a guessing game as to how things were working out.  Also, film suffered from what was known as reciprocity failure so you could really extend the exposure in low light without necessarily ruining things.  Digital is a lot more linear and also gives you the chance to see how things are coming out and have another go.

A lot of the attendees had done this more than once and had come equipped with a variety of tools to play with.  Lights on stands, wands of different LEDs, huge flashlights etc.  Plenty of things to work with.  I had brought some tools along but was definitely keeping it simpler.  Joe offered us some lights to work with but, since this was a new effort for me, I decided to keep it simple and try to get one approach worked out.

I had a tripod so I could leave the camera in place and then a couple of strobes to play around with.  I had to make some set up adjustments first.  Take off IS from the camera since it can wander over long exposures and make things blurry.  Second, put the strobes on manual power and experiment with how well they do illuminating things.  What I didn’t do but should have with hindsight was to go to bulb mode rather than 30 seconds on the shutter.  At some points with the larger airframes, I was very frantic in trying to get everything lit in the 30 seconds.  It proved to be rather energetic, and I was pretty pooped by the end of it.

I would open the shutter and then move around the airframe illuminating it with pops of the strobe.  I quickly learned to shield the strobe, so it didn’t illuminate me and add me in to the shot.  I also came to realize how the larger areas when I stood back a bit needed more light to compensate.  All of this is logical but not something I thought of before trying it.  More research/planning would have been a good idea.  I was also surprised how my shadow could show up in some shots when I have no idea how it would have got there.

I did photograph some of the more famous assets in the collection – how can you ignore a B-58 or a B-36 – but I did also take time for others that were just of more interest to me.  The size of the place meant you could easily not come across one of the other photographers for a while.  They were helpful in pointing out the hazards of guy wires.  Some of the larger planes have wires to stabilize them and these are basically invisible in the dark.  If you are running around popping off flashes, you could easily collide with something unyielding.  Fortunately, nothing like this for me but maybe some luck in that?

Would I do it again?  Absolutely!  It was very interesting and got some nice results.  It also taught me a lot about what I wasn’t doing right and would set me up for a few ideas of how to do things differently in the future.  I think a large flashlight would be an addition I would make, and I would definitely use the cable release and bulb mode.  My thanks to Joe for taking us along and to the team for letting us join in. 

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.

iPhone RAW Image Exposures

When RAW capture first became available on my phone, I started to use it.  Initially, I had to use a third party camera app which was fine but it did have some quirks about it and some things that just didn’t work right, despite some extensive communication with the developer.  Then the camera app of the phone got updated to allow RAW capture and I have been using that ever since.  There is something very strange about it, though.  When I import the images in to Lightroom, they are always about one stop overexposed.  I am curious whether this is a function of the raw format for Apple in order to preserve details in the shadows or whether it is a weirdness with my phone.  Included are two images – one with the base settings after import and one edited.  This is representative of what I get.  It doesn’t hurt the end result but it is rather strange.  Anyone have similar results?

Playing With an Old CRJ Moon Shot

For some reason, I recently came back to an old photo I took of a Delta Connection CRJ900 as it climbed out of O’Hare.  It had climbed right by the moon as it was rising in the eastern sky towards the end of the day.  I had liked the photo at the time but now I was thinking about how to do a better job of editing it.  Now I have been using the masking tools in Lightroom a lot more, I figured I could take different approaches for the jet and the background.  The results were a lot better than my original efforts and I quite like how it now looks.

Time Lapse Experiments With Ice

I used to play with time lapses a fair bit.  I would shoot a series of images and use LRTimelapse to process them. However, that software had a license agreement that meant, when they upgraded the software, they required you to update your license and the old version was deactivated.  This was very annoying.  I figured I would be able to keep using the old version but apparently not.  I don’t do it that much to justify the cost and was disinclined to use that software after this experience.

My latest cameras have a time lapse function built into them which I had been meaning to try out.  I had done this on my little M6 but not with the latest bodies.  What to use them on, though.  I figured an experiment doesn’t require me to be original in the subject.  Just try it out and see how it works.  Consequently, I thought melting ice would be good enough.  My first effort was not successful.  I hadn’t given it enough time to record the melting fully.  Second was better but, while the timing was okay, I had focused on the ice cube when it started melting and it slid across the plate as it melted and out of frame.  The mode on the camera sets focus and exposure on the first shot so this meant everything was well out of focus.

This is why you experiment with things.  The last try worked pretty much as intended.  (I should note that I did all of these in the evening, so the lighting didn’t change during the shoot.) I had a long enough time for the ice cube to almost fully melt, it didn’t move, and the lighting was fine.  Watching the ice disappear and the cube gradually sink into the water that is progressively growing was rather fun.  This isn’t some epic revelation of the nature of melting ice, but it did teach me about some functionality of the camera.

Which Do You Prefer and Do You Care?

As mentioned in other posts, I have been playing around with lower shutter speeds when photographing planes at Boeing Field.  Getting a blurry background to emphasize the speed of the plane is the goal and it also removes some of the annoying distractions that a cluttered airfield can provide.  I use filters to reduce the light in order to get the shutter speed down without having ridiculous apertures.  Naturally, I end up with a bunch of blurred photos which get deleted but the selection process for the keepers is what this post is about.

I have some photography friends that don’t like the effect that the differential speeds of the parts of the airframe have on sharpness.  A sharp nose might mean a pretty blurry tail since the relative motions as I pan are different.  When I am filtering through the shots, I often “focus” on how the nose looks since it is like having the sharp eyes on a wildlife shot.  I care less about the tail unless it looks terrible.  However, getting the middle of the airframe sharp might result in a sharper overall shot even if the nose is a little blurry.

These are the things I was thinking about with these shots of a 777X landing at Boeing Field.  The reason for the post is to see what matters to other people.  These shots are a mix of which part of the airframe is sharp and which bits are more blurred.  I may spend a fair bit of time deciding on which is best, but I wonder whether anyone looking at them is going to like the same things as me or will even care about it.  Maybe the composition of the image is all that they care about, and the pixel peeping is irrelevant.  I would really appreciate feedback if you have an opinion.

Focus Stacking the Lily Pond

A walk in Washington Park Arboretum in Seattle took us by one of the ponds that is covered in lilies.  Unlike when I was in Juanita Bay, this pond allowed me to get down to water level.  This provided a far more interesting perspective across the pond to the trees behind.  It did put me very close to the foreground elements so I focused stacked some shots to provide a deeper focused range across the shot.  I far prefer the lower angle as it really emphasizes the foreground elements in a way that isn’t possible when higher up.

Almost Directly Under the Approach

Photographing airliners can be a little “samey” since there are lots of very similar jets and getting a shot of them from the side looks much like any other shot unless the aircraft is specially painted or the lighting is particularly unusual.  Consequently, every once in a while, it is fun to try and shoot from a different angle.  The approach to SEA when the planes are on a southerly flow brings them in over a part of Burien where you can get yourself pretty much under the flightpath.

It won’t take too long before you are again getting a sequence of repetitive images, so it isn’t going to be useful for much time, but it is a chance to do something a little different.  Head on shots from a distance are possible.  Then you can get the shot looking up from the underside.  This might be a tight shot of a part of the airframe, or a wide angle shot of the whole thing.  An opportunity to do something a little different when you are photographing aircraft that are not ones where you care about missing the shot as you might when something special is coming in.

Playing With the Bizjets to Experiment

I have been messing around with low shutter speeds for traffic at Boeing Field a lot this year.  Some of those shots have made their way into posts on here.  One sunny afternoon, I was at the field and there was a lot of business jet traffic but nothing terribly special.  This provides a good opportunity to try different things.  I had the polarizer and a neutral density filter.  The polarizer is good on sunny days for taking down the glare and it also cuts the light.  However, the neutral density can really pull the shutter speed down.

Since I didn’t care if the shots were a failure, I was willing to just keep bringing the shutter speed down and down.  I compensated by cranking up the frame rate in order to increase the probability of getting a sharp one.  This is an interesting challenge.  Normally I spend a bit of time culling out shots that just aren’t sharp but, when playing with silly shutter speeds, you need to re-calibrate just how sharp things should be.  What is a little off when zoomed in might be of no concern when looking at the full image.  That is not an excuse to let plainly bad shots through though.

Here are some of the results that weren’t too bad.  Even an average Challenger can look a little more interesting with a very blurry background!
