Mixing Channels - The Making of a B/W Picture

A brilliant Sunlight day with lots of bright blue sky and plenty of clouds, just right for a bit of infra red photography. Pity the wind was so bally cold.  A good job I'm not related to any brass monkeys. I was trying out a new IR filter on the 'full spectrum' 1200D. This one is infinitely adjustable from 530nm  to 720nm.

This photo was taken with it set to 530nm and the camera white balance set to the green grass.

Result as seen and taken by the camera:

IMG_8628

The RAW file was adjusted for contrast and black level in Affinity Photo. Then the channel mixer was used to adjust each Red, Green & Blue level independantly on each R G & B channel:

Finally that was changed to B/W (greyscale) with a tad more tweaking:

Closer by Tube

No, not underground photography but using extension tubes to take macro shots.

A short while ago I spotted a set of extension tubes for sale on eBay. Lightweight alloy by the feel of them. Full electrical contacts are fitted so auto focus works as normal. This set is designed for Canon DSLR cameras and consists of three tubes of different lengths so you can choose which to use depending how close you want to get.

DSCN7092

These hand held photos (uncropped) were taken with the 'full spectrum' 1200D set for B/W, 21mm tube with 24-105mm zoom lens. Live view was used on the camera:

A small cactus: (1/100  f8  67mm) middle branch is bout 6mm across

A miniature daffodil: (1/160  f8  92mm)
IMG_8595

I was pleased the outdoor daffodil worked as there was a breeze wafting the flowers about.

The advantage of using tubes is no extra optics so no added distortion. The disadvantage is the longer the tube used the more light is lost = slower shutter speeds and / or wider apertures for the same exposure. The 21mm is about 2 f stops slower compared with no tube.

This set seems to be a snip at just under £15 with free p&p.

Video Title Experiment

It's nice to have something new to exercise the remaining grey cell. This time it's animation. A couple of days ago I spotted the Mac app called Crazy Talk Animator 2 Standard Edition had gone free for a while so I just had to download it and have a play. This is about the most basic version they make and you have to work with the backgrounds, figures, animation they supply. I've always wanted to make a short animated intro for my videos so thought I would have a play.

Some rather poorly lit, grainy video of Blue Tits taken earlier in the year:




Small Tortoiseshell and Peacock butterflies filmed earlier in the week:



The animated sequence was saved as a .MOV video file then imported in iMovie and added to the
video clips with associated music where needed.

Of course the idea of giving away the basic version is to entice people to buy the Pro version for £75.

Home From Home

A few years ago I installed an insect house but all I ever saw in it were spiders webs.
It has now rotted away and been replaced with a new one:

DSCN7103

I fixed the new one in different place a couple of weeks ago. I was wondering whether it was in too much direct Sunlight but as I went to move it I saw it has its first resident already:

DSCN7101

A bit closer crop:

DSCN7102

Yes, a 7 spot Ladybird.
Needless to say I left the house where it was.

Early Flutters Feeding

Yesterday started cool but the Sun soon came out so I decided to trim some of the evergreens in the front garden. Pleased I had my trusty pocket Nikon with me as I saw some 7 spot Ladybirds:

DSCN7071

Some bees enjoying a feed on the Heather:

DSCN7085

But what caught my eye was about five Small Tortoiseshell butterflies on the Heather:

One looked very much well worn and tatty but the rest appeared pristine.

Now There are Two

This is the progress on the first Cymbidium orchid to show a flower spike. Looks as though it will lose one bloom but the remaining five seem to be progressing nicely:

DSCN7069

Joy on joy - I spied a flower spike on one of my larger Cymbidium plants:

DSCN7068

Looks as though last Spring's dividing and re-potting is showing results.

A Frog He Has a Wooing Been

To be honest I haven't seen or heard a frog yet this year but when I had a look at the pond a few minutes ago there was plenty of frog spawn to be seen:

 DSCN7065

Having a quick search through recent years this looks to be the earliest by about a week.
Most years it appears around the 20th of March.

Hoping for Big Things

I spotted some seeds of giant strawberries for sale so I thought I would give them a try. The seeds spent about 3 weeks in the freezer, as per the instructions, and are now sown in pots on the kitchen windowsill. Now it is a waiting game to see whether they start growing as, apparently, they are not an easy plant to get started. The seeds are tiny as can bee seen with the two I found still in their plastic bag, now planted with the others:

DSCN7064

The 5p coin is about 19mm across.

I wonder whether this is a similar variety to the Spanish strawberries available in shops at the moment.

Not so Grey After All

Although I set the 1200D (converted for full spectrum photography) to take B/W photos it appears that it stores all the colour information in the RAW files. This can be seen depending which program is used to process them. None of these have been adjusted for exposure or contrast, etc..

The photo as it will be seen on the camera's screen:

IMG_8563lyn

When pasted in Dramatic Black and White:

When pasted in Affinity Photo before processing as B/W:

IMG_8563ap

And when pasted in Simply HDR:

Lots of possibilities from the same photo.

A Walk on the Grey Side

Today has been a beautiful Sunny day though with a really biting cold wind. Anyway, I decided it was good enough to take the 1200D (full spectrum converted) with us when we went for our mid-morning walkabout. It was also a chance to test out a new (to me) lens which I had bought, used, on eBay. True to the listing it is in pristine condition. A Canon EF 24-105mm 1:4 L IS USM lens. All shots were taken using live shooting which, though much slower in focussing, is the only way to be assured of properly focussed results with a camera converted to accept near IR as well as visible light as they focus at slightly different points.

The start of the walk takes us through the small estate just behind my property.
First glimpse of the village church without its scaffolding:
IMG_8541

A bit closer view:
IMG_8543

On to the main street and a view of one of the old trees:
IMG_8544

Cross over the street for a quick look down Old Mill Lane:
IMG_8547

A howling icy blast down there so back to the main street:
IMG_8545

Cross the street again and down Mill Lane:
IMG_8549

Until we reach a footpath which will take us to the back of the churchyard:
IMG_8551

IMG_8553

Then in to the old part of the graveyard to get a better view of the church:
IMG_8557

Back on the main street looking back. The building on the left used to be our village post office and general store until it was decided to reduce the number of small post offices in the country:
IMG_8563

A quick look at the old rectory which is now home to Penny's doctor:
IMG_8564

Finally back to our own lane:
IMG_8567

A walk on the grey side? Well, I had decided that this outing I would concentrate on B/W (greyscale) photography. All were taken as RAW and then processed using Affinity Photo. Lots of fluffy white clouds an hour before we went ou and a couple of hours after our return but virtually clear sky just when I wanted some cloud!

Full Spectrum

I recently purchased a used Canon 1200D body which has been modified to a 'full spectrum' camera. The original internal filter over the sensor has been replaced with borosilicate glass. This has a high transparency in visible, near Infra Red and Ultra Violet light. The latter two being filtered out in a standard digital camera.

A couple of photos taken to test out the camera, unfortunately on a dull day.
They were processed using Serif Affinity Photo.

Colour:

and one converted to grey scale (B/W):

Orchid Progress

The flower spike on the Cymbidium seems to be coming along well:

Looking forward to being reminded what the colouring is on this one as it's two or three years since it last flowered.

Last Week's Weird Wednesday

This Tiny Planet:

DSCN5060_HDRw

Started out as this HDR scene across the fields at the end of my lane:

with some added clouds and star trails.
