When opening an image for editing in Dehancer, the image does not appear.

Unfortunately, this error occurs for some users of Dehancer Photo 2.4.0/2.5.0 beta2. The developers are working on a solution to the problem. As a temporary solution, you can install version 2.3.6.

Dehancer may not work properly in Windows if system paths contain Unicode characters. To solve the issue, follow these steps:

1. Sign in as Administrator

2. Open the Start menu and click the Settings ‘gear’ icon.

3. Click the Time & Language → Language on the left side.

4. Click on the Administrative language settings link on the right side.

5. Select the Administrative tab and click the Change system locale button. Depending on the Windows version, this setting may be found in an alternate location, for example: Start → Settings →Time & Language → Date, time, & regional formatting → Additional date, time, & region settings → Region →Administrative → Change system locale

6. Enable the checkbox BETA: Use Unicode UTF-8 for worldwide language support and restart your computer.

How do you adjust the look of Dehancer after closing it once? Right now my work process is to make some base adjustments to calibrate the image, then open the Dehancer plugin and set my film look, then close it, add some highlights or boost/take out colours but how do I then go back and edit my film look? How to do it in Lightroom?

It’s technically impossible within Lightroom plugin image processing pipeline. 

1. Use the Last Edits and Presets functionality to store your intermediate image state. 

2. Use the built-in Dehancer tools for highlights adjustment (Film Compression, Film Developer, Expand, Analogue Range Limiter) and Color Boost.
