A question about making a semi transparent image

Howdy!

Can someone explain to me how to put a semi transparent background in an image using Photoshop?

What I’m doing, specifically, is taking the logo for my forum (let’s use my coin forum as an example), and take the text logo and have a background color in the image file that is semi-transparent.

So, I want to put a background in the header that is some old coins, then have the logo have a semi-transparent color behind it so the text logo stands out betteer.

Can’t figure out what to do in Photoshop to make that happen and was getting frustrated trying to find something searching in Google.

Thanks!

In the layers panel, try using the opacity option on the layer that you want to be semi-transparent.

To blending background what I normally use is reduce filling effect at top of layer from 100% to what I want .
