On Friday afternoon I had a walk along the river at Denso Marston Nature Reserve.
Over the years I have wandered along the river from Dowley Gap to Esholt and along every part I have seen or heard a Kingfisher at some time. The river on Friday was no exception.
With a pose like that this Kingfisher, if turned to black and white, looks like a Corvid, except that it is about a quarter the size.
In this shot the length and shape of the beak means there is no chance of confusion even if those gorgeous colours had not already shouted “Kingfisher” at you..
This bird was a pleasant surprise for me, a Pied Flycatcher, a first for me. They are Summer visitors to the UK and seeing one at this time of year is a bit on the early side. I think Baildon is on the edge of where you can expect to see them. They can be spotted on the coast as they pass through to areas West of Baildon, another reason to be chuffed to have seen it. It appears to have been ringed at some time.
Other interesting sightings were a detectorist (?) and someone hiding from the sun.
Other things spotted were Mandarin Ducks (above and featured image) Goosander, Mallard (+chicks), Crow, Jay, Blackbird, Wood Pigeon, Blue Tit, Great Tit, Bullfinch, Kestrel, Chiff Chaff, Wren, Mistle Thrush, Magpie, Grey Heron, Moorhen (+chicks), Canada Goose, Frog, Orange-tip butterfly, Comma butterfly, Small Tortoiseshell butterfly, Brimstone butterfly
As you know it is the breeding season for birds and today I saw that Mallard and Moorhen have hatched their young along the river and at the reserve. One Mooorhen pair at the reserve has 6 little balls of black fluff that float around with little pink/red beaks stuck out. A Canada Goose is also breeding there. Steve has very sensibly put some extra signs up about the need for dogs to be on a lead in the Nature Reserve. Not only is their a risk of dogs scaring the adults away from nests (a Moorhen nest was lost last year due to this) but the geese will be very protective of the nest and young and will attack anything invading its space in a rather noisy and alarming manner. These are not pets.
I have spent far too much time recently trying to sort through my photos so I decided I was long overdue for a wander or two. This time it was up to Baildon Moor.
It was great to hear Skylark up in the sky and I even managed to spot them on a couple of occasions. Tiny dots fluttering away high overhead.
I did spot one on a wall with its crest up. It spent most of its time looking down to the other side of the wall where it seemed a Skylark was singing. I thought they sang when up in the air.
At this time of year Lapwing are breeding on and around Baildon Moor and this one is trying to distract me from its nest. They often fly up into the air to dive bomb larger birds that fly by.
After moving away from it I could see that it had gone back to its nest.
A couple of Hares showed themselves for a few seconds….
.. before running off to deeper cover.
I was a little surprised to hear a Snipe calling and spent some time looking along walls and fence posts until I spotted one. At about the same time I heard one calling to my right and then another making a thrumming noise with its tail feathers during its dive but didn’t spot them. I’ll be trying later in the year to get a decent shot of a diving Snipe.
I was also pleased to see and hear Golden Plover. A couple of times about 60 took to the air and flew around a bit before settling down to feed on the insects and worms.
The Plover tend to stay together but one slowly wandered away from the others feeding as it went.
It looks as though it heard my shutter a couple of times or perhaps saw me move.
Most of the others seemed to be disturbed as a Crow flew over and flew, as a flock, further away. The lone one kept perfectly still for a while before running then flying off to join the others.
A couple of times the whole flock took to the air and I did try using a photo of that as the header image, the one right up near the top of this post, but it just looked like 200 black dots across the screen so I swapped it for a zoomed in crop of a flock. On a phone the black chests of the male Golden Plover in the photo above probably look like little black smudges – it looks better on a 27 inch monitor. 🙂
This is a rare posting to the Photography side of my website. I should do more of them. If I do I might get comments that point me in a better direction. This post seems quite long but I find the process quite quick and simple.
RAW files from my camera are, as the name suggests, the raw data from the camera and its sensor. I am sure I am simplifying things a lot, and I may actually be wrong for some cameras, but it helps in the understanding of the principle. Each pixel in a camera is made up of 3 sensors that record one of 3 colours and the data from these sensors form part of the RAW data along with how the camera is setup. To view a RAW file the application has to be able to understand the data and then apply the recorded camera settings to that data before displaying. For example the file contains all the data for the 3 colours for each pixel but you might have set your camera to black and white. The application reads the RAW colour data and then displays it as black and white. This is what the DPP software that comes with my Canon camera will be doing.
On my Canon 7DMkII the RAW file includes an embedded JPEG where the camera settings have been applied to the RAW data. I suspect that image viewing software uses this embedded JPEG which is probably stored within the file in a standard way – at least with a particular manufacturer. In that way the image viewing software will still work with the embedded JPEG when a new camera, with new RAW data, is released.
On my computer I find that Irfanview, that I use to do the first review of image files, displays JPEG files quicker than RAW files. This means it can be quicker to go through the many files and get rid of the first 90% of them.
There are times when I am not interested in the RAW file and its mass of data, say when I am taking some shots of the change in use of buildings in Baildon for nostalgia/history record purposes, where the JPEG with perhaps some simple contrast, cropping and straightening applied is more than adequate.
For the 2 reasons above I often use an Open Source program called UFRAW in “batch mode”. UFRAW has a user interface that lets you manipulate the data of RAW files and export as graphics files e.g. JPEG. I no longer use the user interface – I use Canon DPP instead. But I do use UFRAW in batch mode to quickly extract the JPEG from RAW files.
This command tells ufraw-batch (installed in the Program File (x86)) to read the RAW files (*.CR2) in the directory and extract the embedded image and put them in the “embedded” directory.
I copy this .bat file to the directory containing the RAW files and run it.
The routine very quickly extracts the JPEG files so that I can either use them straight from there or use a file viewing application, in my case irfanview (and “Yes” I know Microsoft photos viewer probably works quicker, but old habits and all that….), to review and delete those not needed. I then delete the RAW files associated with the JPEGs I have deleted and start processing the remaining RAW files where I probably delete another 90%.
But why go through all this process? Why not tell the camera to save in JPEG in the first place? To put it simply:- by saving in RAW I have the data from the camera and so the image I can get from that is limited only by the camera. If I save as JPEG I am then applying the limitation of the JPEG file format on top of the limitations of the camera. Each pixel will be limited to a range of colours (admittedly enormous, but it still applies) and the file compression used throws away information that can then not be recovered – and each time you load, edit and save the JPEG more information will be thrown away. (This is why TIFF files are used when you don’t want to loose quality with each save after edits but that’s another topic.)
You can’t beat “getting it right in camera” but there are times when you don’t get it right, or when using one file from the camera, processed once, doesn’t give you what you want. I’ll cover the first example below but the second example is covered in another blog post here.
The image above is taken straight from the camera with no processing. It was shot as RAW and shown here as its JPEG. In this case it was deliberately under exposed but I can assure you that in the past I have had examples like this where I have got it seriously wrong .
I have then taken the JPEG and processed it as much as I dare. The colours are all wrong and it is very noisy.
The image above was processed as a RAW file before exporting to JPEG. It is still not a good photo but the colours are much closer to reality, there is a lot less noise, it is usable. Since taking this photo I have upgraded my camera and would expect to be able to get more from the RAW file, but the JPEG would still be the same.
The photo of Adam was taken during a Baildon Camera Club session.
