Diary

This contains images from activities I have worked on.

Audio

Audio is an integral part of the images that I display.  Images such as waterfalls, waves, landscapes, trees all have audio as a background experience when capturing “a moment/period in time”.  This can applied whether the image is displayed at a rate of one per minute or 24 frames-per-second (video rate).

I have been taking advantage of the Australian spring weather (little or no wind) to go out and record various ambient sounds.  I then “clean them up” for playing as typical for the location of the image capture.

Here are some short examples.

Magpies have a beautiful song but are aggressive in Spring and “swoop” from behind to protect their young.

 

Port Elliot waves.  I used this for a background video that shows waves breaking on rocks.

 

Para Wirra Conservation Park Frogs.  These are found in many of the creeks and wet areas in the Adelaide Hills.

 

Seagulls. I will use this in various ways in my sea-waves images.

 

Waterfall.  This clip was recorded at the bottom of Morialta Falls.  I had to place the microphone close to the bottom of the falls to get the sound of the water hitting the rocks.  I then added some bird and frog sounds from the valley below the falls to give more representative ambience.

 

Blackbird.  This bird introduced into Australia can be heard in many locations around the world.  This was recorded outside my office window in suburban Adelaide.  I use it as part of various landscape image sequences.

Changing flower images

I like to look at flower images.  However – not as single images.  The clip below is a summary of an image sequence (250 images) of a daffodil rotated through 120 degrees.  Thus each time I walk past the picture frame, a different view is shown.

Update on 360 degree videos and panoramas

My son has been travelling in Europe and has been posting 360 videos (using the Nikon 360) and panoramas on Momento360   [https://momento360.com/ ] .  This is way better than conventional smartphone narrow images in terms of ambience and experiencing the location.  When he returns I will be able to put the fixed panoramas on an electronic display as a reminder of what he experienced.  Love it!

Morialta Falls video

As part of my project to collect videos to run on background electronic displays, I have added a recent video “Tryptic” of the Morialta waterfall.

The actual video runs for 20 minutes and includes ambient sounds from the area.

360 degree videos and panoramas

I have been exploring the new world of immersive images.  This could be considered an extreme version of the continuum from paper prints, to electronic wall displays, to displays that you interact with, to displays that you wear.

Using a Nikon KeyMission 360 camera that captures a 360 Field-Of-View I captured various scenarios.  The video below contains some clips that I captured on a walk through the Morialta Conservation Park in Adelaide, South Australia.

When you play it via Vimeo, make sure you select 4K video.  You can use your mouse to scroll left/right and up/down.

Morialta walk 200717 from victor demczuk on Vimeo.

It poses some challenges in terms of soft imaging (4K is inadequate when spread over 360 degrees), sun flaring, and operator visibility.

The video can also be viewed in a Head Mounted Virtual Reality Display.  These can be bought for $100 or less and use a smartphone that clips into the display.  The user just moves their head around to see the full 360 degree image.  I used this technique on a couple of dinner party videos and it was very engaging and even hilarious!

I am loaning the camera to my son and daughter who are going to Europe (son) and Japan (daughter).  It should be great for tourist type videos and stills.

Speaking of stills – the camera takes 360 degree panoramic stills.  These can be displayed on electronic wall displays using the still picture sequence technique that I talk about on this site.  Thus I could display a series of still images that over say, 30 minutes does a full 360 degree rotation of a particular scene – great for memories of various locations.

[7 July 2017]

When I first printed the image below, I was pleased with it.

However after a while I got bored with it.  So I have now converted it to a zoom sequence of 480 images that when displayed at a 5 second rate takes 40 minutes to cycle.  So, as with other sequences below, each time I come into the room where it is displayed – a sightly different version is displayed, which I find more interesting!

Instead of a single image of a flower, this is a set of images of a flower from different angles, thus capturing more of its characteristics.  It was taken by rotating the flower in front of a fixed camera.  The flower was rotated at discrete 5 degree steps (approximately).  This allowed me to take a series of images (16) at varying focal points that were blended so all the petals were in focus and the background was not.  When each angle is displayed for 5 minutes the sequence takes some 80 minutes to repeat.

This is an image sequence of a sunset I captured a couple of months ago. The clip is a speeded up (time lapse) version, but I have converted it to some 480 single images that when displayed for 5 seconds takes 40 minutes to repeat.

[15 June 2017]

I recently photographed an Orchid show.  I tried out a feature in my Panasonic GH5 camera – it can automatically take a number of images at different focus points.  This is ideal for close-up flower photography as the full flower can be in focus and nothing else.  I was happy with a number of resulting images.

Since I have only limited wall space to hang photographs, this was ideal for electronic picture frame display.  I let each image display for 5 minutes and 50 images takes just over 4 hours to cycle through.  Again, each time I walk through my dining room a different image pleases me.

Port Adelaide Wharf panorama

I display two panorama on a 10 inch display in my kitchen.  It displays day and night panoramas of a part of the wharf.  The panoramas each consist of some 3000 still images at a resolution of 1920 x 1080  pixels.  Each image is displayed for 5 seconds.  Each panorama takes 4 hours to go from left to right.  Unless you look closely, you don’t notice the image change.  Thus each time I wander through the kitchen area there is a slightly different view of the wharf area.  The view could also be a day or night view. The images take up some 2GB of storage.  The display is set to turn on at 7am and off at 11pm.

Second Valley Rocks

I have had some single images of a cliff face at Second Valley, South Australia displaying on a 15 inch (308mm) display for some months in my dining room.  What was lacking was the variety of textures in the rocks.  A single image, while interesting, was inadequate.

So I rephotographed the rocks, this time making multiple images which I then stitched together as “panoramas” in LightRoom.  I then made an image sequence in Panolapse of some 900 images at 1920 x 1080 pixel resolution (2.6GB).  With a 5 second delay the full sequence takes 1.25 hours to cycle through.

 

I am happier with how the variety in the rock texture is now captured.  I will now add a number of image sequences from various viewpoints that captures the dramatic variation in the cliff face.
