Render an image in its original colors (without lights inside the scene)

Hello,

I have a problem right now that I don’t really understand. I haven’t worked with Blender for a long time and hope you can help me.

I have a simple picture (grayscale). This image should be rendered as a texture on a plane. All grayscales should be displayed as they are in the image. So white should be really white and black should be really black.

My approach was to simply link the image to the color input of an emission shader. Unfortunately the picture is then grayish.

What am I doing wrong?

EDIT: I would like to use Eevee

because of the filmic color transform that is now default in blender
you can turn it to standard and everything will be exactly like in the source image:

Thank you so much, everything feels different in this new version. :open_mouth:
