Boa noite, as fotos que visualizo estão no modo negativo, como coloca Las no modo padrão?o

Hi, 

Hope you are doing well.

Sorry for the delayed response. As per the issue description that the photos are showing in negative. As there is no issue observed on our end. Would you mind sharing some more details to understand the issue better?

1. If possible, could share some screenshots of the issue?

2. Is it happing with a particular PDF or with all the PDFs?

3. Make and model the mobile device you are using?

4. OS name and version?

Try to open the PDF on the desktop (Win/ Mac) Acrobat Reader DC application and check if it is doing the same.

Here is a discussion link for a similar issue: https://community.adobe.com/t5/adobe-acrobat-online-discussions/my-pdf-photo-files-all-look-like-photo-negatives/td-p/9791851

Let us know if it helps.

Thanks,

Harsh
