About: "Avelac Lightning"

October 12, 2017

 


This image was created in 2015 during my Ayacucho-ambassadorship in Peru. It was an experience never to forget. As a photographer and an Ayacucho ambassador, I created the photo project 'Dreaming without fear of heights'. Along with twelve other ambassadors we tried to spread the story about the Ayacucho brand and to contribute to the wonderful reputation it enjoys worldwide. This ambassadorship was made possible by the AS-Adventure CompanyBever, and Solid International. I will always be thankful for that opportunity and lifetime-experience 🙏🏾.

About the image. When I first posted this photograph I received a lot of questions about it. How did you do that? What's the meta-data of the capture? Where was this picture taken? Here are the answers... 
 

The image was shot at Avelac. During our days in Peru we visited a lot of companies supported and guided by Solid International. Avalac is specialized in breeding dairy cattle and offers products and services to improve the breeding of lifestock and the living conditions of the farmers and their families. Avelac is a self-sufficient social responsible company that offers quality dairy cattle in the Ayacucho area. Avelac also acts as a model farm and educational center. When visiting the company we got stunned by forces of nature. Together with filmmaker Ben Steensels (www.bensteensels.be), we decided to go for some footage when we were on 4000 Altm. 

The image like you see it, is a time-stacking of 16 images. A what?
I will try to explain. An image stack combines a group of images with a similar frame of reference, but differences of quality or content across the set. Once combined in a stack, you can process the multiple images to produce a composite view that eliminates unwanted content or noise. 

So it is Photoshopped? Yes, of course! This image needed to be post-processed in specialised software.  

You can use image stacks to enhance images in number of ways:

 

  • To reduce image noise and distortion in forensic, medical, or astrophotographic images.

  • To remove unwanted or accidental objects from a series of stationary photos or a series of video frames. For example, you want to remove a figure walking through an image, or remove a car passing in front of the main subject matter. 
     

So, if we are more specific. Stacking photographs made from a locked off tripod over a given duration is not a new technique, and has been commonly used for creating star trail images where single super long exposures can be troublesome. In this image, I wanted all the lightning in one single photograph. This application of the process is particularly interesting and beautiful. An extension of timelapse photography, the Time Stack technique’s goal is to show the passing of time in a single photograph, rather than through a moving video. For best results, images contained in an image stack should have the same dimensions and mostly similar content, such as a set of still images taken from a fixed viewpoint, or a series of frames from a stationary video camera. The content of your images should be similar enough to allow you to register or align them to other images in the set.

 

About the meta-data. Hereby the basic summary of a single capture in this image.

  • Model: Nikon D800

  • Lens: 70-200 f/2.8

  • Focal Lenght: 70mm

  • Exposure: 25,0" - f/16 - ISO400 - manual - Matrix metering


Hopefully you get the "picture" now. 😁

Feel free to contact me if you have more questions.
