Opacity problem

[Mila5C5B]

Hi all,

I am making a flyer and wanna lower the opacity of a picture, but then the background color gets darker. It's really annoying and I don't know what to do. I have the background locked and even then it happens. The picture and background are NOT linked in any way.

Does anyone know how to fix this?

Transparency can affect everything on the page.

Is the "background" object filled with a spot color?

Which Transparency Blend Space is selected?

If your meaning the photo gets darker it maybe the background showing through? Add white fill to your picture to see if that helps. Click your photo and go to fill/white.

It also happens if I add drop shadow to text. The vibrant blue color I picked turns really greyis. I never had this happen before, maybe rgb colors aren't supossed to work?

Please answer this crucial question: what transparency blend space is selected?

It says "object" I think that is was you meant. I'm not sure.

I made a screenrecording of the problem.

There is no fix since is doing what it should, the opacity is going down and you are adding transparency to the image, so we can see more of what is behind it.

The background should stay white or you should have no background if you want to see what is behind the image as you make it transparent.

It’s happening because you have your Edit>Transparency Blend Space set to Document CMYK. When you add any transparency to a spread (your drop shadow), all out-of-gamut RGB and Lab color gets displayed as its nearest CMYK equivalent. You can change the blend space to Document RGB, but keep in mind the blue that is changing in your capture is out-of-gamut and the preview is showing an expected print soft proof.
