How to generate a timelapse from DNG images with Tikee?

In this article, we will only detail how to capture images in DNG format with Tikee, what to pay attention to when developing images, and how to generate a timelapse on our platform.

We will not detail the specificities of the development of the DNG for the timelapse (temporal coherence of the parameters, antiflicker, etc.). This will probably be the subject of a future blog post;)

The Tikee lets you capture in DNG format. This standard format, created by Adobe, allows to store RAW (raw sensor) image as well as information about the camera and shooting conditions in order to be able to “develop” it in a dedicated software (Adobe Lightroom CC by example). This workflow is highly appreciated by photographers because it allows to obtain a personalized rendering of the colors, and to make anti-noise and edge enhancement adjustments different from those proposed by the camera.

Capture images in DNG format

 

This mode is currently only available for “long-term” timelapses.

When setting up your time lapse sequence, select “Raw” for the “Image Format” (see image below). You will notice that the “uploading of images” is automatically de-selected: the size of the files generated would have an impact too important on the autonomy of the camera if we transmit them by Wifi or 4G. The files are stored on the SD cards and you will have to recover them at the end of the capture sequence. The rest of the configuration is done as usual.

Importing images

 

Once your SD card is recovered, import the files into your favorite development software. For Lightroom: Import> “Copy” will copy the files to a folder on your computer and add it to your library.

Import DNG

At this step, you must be careful not to rename the files.

In addition, if you are used to editing import metadata, be careful not to touch the “DateTimeOriginal”, “Maker”, “Model” fields to import them to my.tikee.io later.

Image development

 

At this stage you can give free rein to your creativity.

However, keep in mind that the images are intended to be merged later into a panorama. So avoid treatments that are not uniform in the field such as:

  • vignetting
    radial filter
    graduated filter

One imperative* (if you want to use the panoramic format): no cropping, correction of the objective, or other geometric transformation.

*not necessary if you only use pictures of the right sensor or of the left sensor.

Exporting images

 

When exporting, do not:

  • Change the name of the images. For example, an 000123_LEFT.dng image should be exported as 000123_LEFT.jpg.
  • Delete the metadata. The same fields as during the import are to keep: “DateTimeOriginal”, “Maker”, “Model”.

Some additional tips:

  • JPEG quality can be changed. It’s up to you to find a good compromise between the weight of the output files and image quality. We recommend a value of 70. See our comparative study here.
  • The output resolution can also be changed. But be careful, this will have an impact on the resolution of the generated panorama. We recommend leaving the maximum resolution.

Creating a project on my.tikee.io

 

In your personal space on my.tikee.io, create a new timelapse (“+” button). Drag your files to the area provided for this purpose to start the upload, or click on the “cloud”.

Projet DNG

It takes at least 100 pairs of images to start the merge and 150 to create a video.

After a few moments, your video will be ready.
