Merry Christmas 2017 - & Happy New 2018!

Christmas has been and gone for another year, and a new year is just around the corner. But it's not here quite yet, so I figure I can sneak in a Christmas post just before 2017 ticks over to 2018!?

Christmas Angel. Olympus OM-D E-M1 with 12-50mm EZ lens. f5.4 @ 1/3rd sec, ISO 200.
Every year, a week out from Christmas, Greymouth holds a Christmas Tree Festival. Local businesses sponsor a tree and decorate it, and then the public give a gold coin donation to come and have a look at all the trees decorated - and to vote on their favourite. It's a local fundraiser and a very popular event. It's also an excuse every year to get the camera out and have a 'play'.

Christmas Light Painting. OM-D E-M1 with 12-50mm EZ lens. f10 @ 1sec, ISO 200.
A very dark room, with very brightly lit trees, is just crying out for some long exposure experimentation. Last year I concentrated on shooting out-of-focus lights (see the post here), whereas this year I decided to go for long(ish) exposures and camera/lens movement. With the Christmas Angel I zoomed the lens out while taking the exposure. For Christmas Light Painting I simply used a 1 second exposure and moved the camera while taking the shot. Both simple, yet effective techniques that I don't do all that often.

Blue Icicle. Olympus OM-D E-M1 with 12-50mm EZ lens in 'macro'. f6 @1/100th, ISO 640
I don't just experiment with long exposures. I also try to shoot some of the lights and decorations as they appear. The macro function on the 12-50mm EZ Zuiko lens is great for this. It allows me to get some very detailed shots - hand-held - with the aid of the amazing IBIS (in built image stabilization) that Olympus is famous for. Even at f6, ISO 640 was giving me a hand-holdable 100th of a second exposure time. Even so, the RAW file was quite dark when I opened it in Light Room. But a quick move to the left of the shadow slider and a fantastic amount of detail appeared in the shadows. And ISO 640 is pretty clean on the E-M1, so no noise reduction was necessary.

Christmas Bell. Olympus OM-D E-M1 with 12-50mm EZ in 'macro'. f6 @ 1/20th sec, ISO 3200 
This ornate Christmas bell also caught my eye, but it was in a very dark corner of the display. I had to go to ISO 3200 to get this image, and even then it was only giving me 1/20th of a second shutter speed! But it's pin sharp (where it should be at the front edge of the bell), thanks again to Olympus's incredible IBIS technology. Image stabilization isn't a cure-all for everything, and is certainly not an excuse for sloppy camera technique. But when you need it, in situations like this bell in low-light, it can be a miracle worker! Hand-holding a camera in low-light, with a 100mm equivalent focal length lens, and shooting pin-sharp images at 1/20th of a second was practically impossible in the film days. IBIS technology not only makes it possible - it almost makes it easy!

Christmas Town. OM-D E-M1 with 12-50mm EZ. f7.1 @ 1/10th sec, ISO 3200
In every town and city up and down the country (and indeed in any country where Christmas is celebrated), decorating your home with Christmas lights is a much loved tradition. And some people go all-out! As well as going to the Christmas Tree Festival, we also drove around to check out some of the more spectacular home displays.

Christmas House. OM-D E-M1 with 12-50mm EZ. f5.9 @ 1/4 sec, ISO 3200 
Here's another great example of Olympus's superior image stabilization in action. At 1/4 of a second, hand-held, everything is still nice and sharp. The E-M1 has 5 axis image stabilisation, while the new E-M1 Mk2 has an even better IBIS system. Apparently people are hand-holding for anywhere up to 10 seconds and still getting sharp images! That's just plain crazy talk!!!

Christmas House ultimate winner. OM-D E-M1 with 12-50mm EZ lens. f5.6 @ 1/15th sec. ISO 3200 
Our final stop for the night was the truly impressive 2017 Christmas House winner. There was a lot of light to shoot by, but even so I was still at ISO 3200. The RAW file needed to be opened up in the shadows to bring out some of the light, and in doing so, there was definitely some noise at ISO 3200. But dialing in some noise reduction in Light Room cleaned everything up very nicely, and I'm very happy with the final images at high ISO's from the E-M1.

Ho Ho Ho! OM-D E-M1 with 12-50mm EZ lens. f5.6 @ 1/15th sec. ISO 3200
Boosting shadows and lowering highlights has given a slight HDR quality to some of the images - especially after adding a little noise reduction and sharpening. I like the effect, since it looks very similar to what my eyes were seeing at the time. Our eyes can take all the detail in, our sensors can't (without a little help later on in software). It's a balancing act to get enough detail in the highlight so that they aren't too burnt out, but still look like points of light - and enough detail in the shadows so you can see what's there, but it still gives a sense of depth and darkness. As much as people worry about dynamic range and noise in the smaller micro four third sensors, I think the E-M1 pretty much nails it!

Santa Clause. OM-D E-M1 with 12-50mm EZ lens. f5.6 @ 1/15th sec. ISO 3200
Would a full frame camera like the Canon 5D Mk3 give a 'cleaner' file at ISO 3200? Of course it would. But so what? It would have also been a lot heavier to lug around for the evening - and I may not even have bothered? Am I unhappy with the files from the E-M1? Absolutely not! In fact, I'm thrilled with them. I've owned a lot of DSLR's in my time, both full frame and cropped sensor (admittedly from a few years ago), and I wouldn't have been comfortable going past ISO 800 with any of them. The E-M1 (and E-M5 MkII I had previously) is the first camera I'd happily shoot at ISO 3200 if I needed to. The results above show why.

I hope that Christmas 2017 was good to you, and I pray that 2018 will be even better! Father Christmas was good to me this year and I managed to get quite a few photographic goodies that I will be testing, using, and blogging about very soon! I also turned 50 at the end of 2017, and my family surprised me with a new monitor for my computer! So I will also be writing about my new office space and using a dual monitor set-up at home. Looks like 2018 is getting off to a good start already! :-)

Sunset on an OM-D EM-5 MkII

In my last post I pondered the oft quoted 'best camera is the one you have with you' line of reasoning in relation to using my Samsung Galaxy S3 to take sunset photos. My argument (and I'm sticking to it), is that unfortunately the 'best' camera is often the one you don't have with you, and you have to settle for second (or third) best.

Why do we spend large amounts of money on camera bodies and lenses? Why do we (some of us at least) agonize over different systems, kit configurations and accessories? Even if we aren't hung up on image quality to the extent of 'pixel peeping', why is it that many of our photography decisions have to do with technical considerations like noise, sensor size or chromatic aberration?

Maybe it's because in this digital age, these are the things that are more easily quantifiable? Let's not talk about composition, or subject matter, or story telling - these are far too subjective and ephemeral topics. Much easier to compare low-light images, sensor formats or lens characteristics. With all the agonizing over IQ or individual sensor pixel density (is that a real thing?), it's a wonder we have any time for actual picture making at all!?

Or maybe, just maybe, these things really are important? And by that I mean individually important. Subjectively important. Important to me. Let me explain what I mean...

Photography is a visual medium. We are visual artists. We like to be visually creative. And so, just like a painter who chooses their paints carefully, we  - as artists - like to choose our tools carefully too. I've heard people say that some photographers spend too much time worrying about the gear and that painters never get together and talk about the brushes they use. Really? I guess these people have never spent much time with painters? All the artists I know have their favorite brands of paint/brushes/paper/canvas that they swear by (and that they have sometimes taken years of trial and error to perfect). So much so that they will almost refuse to use anything else. Does it mean that they can't paint with something else? No, of course not. But does it also mean that they should just paint with anything because surely anything will do?

As a photographer, I have my own set of criteria for how I want my 'tools' to perform. I know the level of noise that I am comfortable with at certain ISO's. I have a sensor size and megapixel number that I am happy with, and certain tolerances within which I want my lenses to perform. I've come to these quality decisions from years of trial and error with different systems and configurations, to the point where I now have a set of expectations of how I want my images to turn out with the tools I've chosen. When I use tools that I know will produce an image inferior to my set of (subjective) criteria, then I feel a slight disappointment at the final result. Even if only from a qualitative standpoint.

Let me be very clear  - my criteria for acceptable IQ is NOT your criteria. You must find you own. The trouble comes with photographers who try to force their own set of criteria onto others, as if it was some kind of law. "You must have a full frame sensor or you're not a real photographer. You must have at least 40 megapixels or you're not a real photographer. Your images must all be noise free at ISO 640,000  or your camera's no good" - blah, blah, blah....

I'd like to end by saying that my image criteria isn't set in stone. It's a fluid, evolving and changing thing - and technology plays a large part in this. A few years ago I couldn't have conceived of hand-holding a sharp image at 1 second. But thanks to the OM-D EM-5 MkII , I can. I was also a full-frame snob for a very long time (yes, one of those). But not anymore. I am also finding that the older I get, the less things like noise and megapixels seem to matter.

And yet they do matter. And I know that they matter when I use my smartphone as a camera and am somewhat unhappy with the results. In a way that I am not unhappy with the results I get from my OM-D EM-5 MkII.
