Stabilise and speedup movie – Death road Bolivia

This year we spend our vacation in Peru and Bolivia with Arja. (20160606-20160704)

We did the Death road in Bolvia, wellll Arja and me. Coline fell ill the day before.

I tried to get a sense of what it was using a action cam mounted on my helmet and speeding it up in afterprocessing.
Shamefully i have to admit, that most of the times my camera was recording my frontwheel ..

To post: script/program to create this effect

This movie has been stabilized and sped up.

See https://en.wikipedia.org/wiki/Yungas_Road for more information.

Starting at 4700 meters and on the good parts going down @70km/h. Then the dangerous parts started. Feeling like ‘offroad’ narrow corners, where you can expect to see a minivan coming around the corner anytime. Steep drops without barriers. Water and land slides.

(Whole story in dutch)

Nikon Lenses

Created a graph for my Nikon lenses. It shows me what lens i can use at what Aperture / Range.

( https://media.henriaanstoot.nl/websites/lenses/ )

It uses canvas to draw lines and text, but thats only interesting for static stuff. ( https://www.w3schools.com/graphics/canvas_drawing.asp )
My example uses a php script to load information from a csv file. And loops though those entries and draw lens info.

Piece of canvas script to draw 17-70mm lens info.

ctx.fillStyle = 'rgba(0, 200, 100, 0.9)';
ctx.lineWidth=2;
ctx.beginPath();
ctx.moveTo(189.98560128675,163.25813588993);
ctx.lineTo(359.81942904592,202.49237972319);
ctx.lineTo(359.81942904592,250);
ctx.lineTo(189.98560128675,250);
ctx.strokeStyle="rgba(0,0,0,0.9)";
ctx.closePath();
ctx.fill();
ctx.stroke();
ctx.fillStyle = 'rgba(0,0,0,0.9';
ctx.save();
ctx.translate( 189.98560128675,153.25813588993);
ctx.rotate(-Math.PI / 4);
ctx.fillText("17-70mm", 0,0);
ctx.restore();

Making a lot of graphics for a book.

Protographing a bonsai we made (360 we made )

Coline is publishing a book for her thesis.

So we had to design Covers and graphics for this.

I used Scibus to make a mockup design.
The graphics in the book are made using Inkscape.

The book itself was written using Indesign.

Inkscape is perfect to create vector graphics. These can be resized to any resolution. So always perfect.
https://simple.wikipedia.org/wiki/Vector_graphics
In the past i’ve used a program like sodipodi, there is something like it now integrated in Inkscape.
This is a tool to convert bitmap to vector graphics.
(Using a small jpg, i could convert it to vector graphics and print it in a huge size)

Inkscape work


Some designs

Web controller for Acdsee

Leave a comment

UPDATE: 2023 It’s still working

I made a webcontroller for viewing images on a big TV.

Using a Acdsee instance with MCE Controller installed and a webserver.

https://tig.github.io/mcec/example_commands.html

Rate the picture 1-5, clear rating, slideshow start, escape, open/close image, zoom-in out and zoom-reset. Previous and next image fullscreen and delete/yes

Some used defined keys (see php file)

 if ($cmd=="I"){ $put="chars:+"; };
 if ($cmd=="O"){ $put="chars:-"; };
 if ($cmd=="R"){ $put="chars:*"; };
 if ($cmd=="Y"){ $put="chars:y"; };
 if ($cmd=="F"){ $put="chars:f"; };
 if ($cmd=="D"){ $put="delete"; };
 if ($cmd=="N"){ $put="right"; };
 if ($cmd=="P"){ $put="left"; };
 if ($cmd=="ENTER"){ $put="enter"; };
 if ($cmd=="ESC"){ $put="escape"; };

Staircase pictures

Leave a comment

Maybe you also have a white area to fill, here is a suggestion.

For years we collected picture frames, weird and ugly.
We wanted to have a collection of images in our staircase, to fill the white area.
The images are all something we like, have interest in or are personal.

It needed to be on 3 walls, so here was my first design.

Most left .. picture around the corner
In the end a total of 110
Around the corner picture frame i made
