The people who hire DPs are not the same people who hire you in other classifications. I don’t know if the work you’re referring to is within the camera department (AC, OP), as a gaffer, or something else. Unless you are working for money as another head of department (Editor, Production Designer, etc.) who are also hired by the people who hire DPs, you’re okay.
Here’s what I suggest: 1. Keep making money in your classification to support yourself and save for the future
2. Build relationships with the people who will know you and hire you as a DP
3. Build your reel as a DP
4. Keep the two separate unless you are 100% sure that your current crew is supportive of your desire to transition
If you have a question, put it in the comment section.
To your success!
