In photoshop there is an option called opacity, and you can edit it through a slider or inputting a percentage (0-100).

Its found on the layers tab, and is effective for what you want.

What are you on about? Do you have this need to post in every IT thread despite the fact its already been answered?

But since you just want to make the background lighter, then you can just use the 'Brightness' option in Photoshop.
Why would you use that? Brightness can screw up how the image is supposed to look without making it 'brighter' as you might want. It works alright with photos to a small degree, but on smaller images for websites, you're more likely to obscure text than make anything 'lighter' :\ :\ :\

Yes there can be two answers to every question, but if the question has already been answered and acknowledged (not in this case), it becomes rude and borders on spamming.

It's a simple grey on white image. Brightness will have no such effect on such a simple image.

So...

your answer isn't relevant towards the original topic since it doesn't have much effect?

How helpful an answer is that? :|

As you can see, by upping the brightness to a similar level, you get rid of certain details, and on more complex photos, the levels would be totally kicked up.

Sure does look different to me.

I can see where you're coming from on it politik, and in really basic images it probably won't be an issue, but in the one provided it is, and it's been said a few times, and now demonstrated.

Quite aside from that though, if someone is looking to make something transparent, is there actually a good reason why one would use brightness to do it instead of adjusting opacity?

It certainly seems more logical to use the latter. In addition to that, it makes a lot more sense to me to learn the opacity method over brightness, so that the ability is able to used in relation to everything, rather than just incredibly basic grey images on white backgrounds.

This is:

Original, Opacity (75%), Corrected Brightness/Contrast (+35/-25), Brightness (+50).


The difference being Opacity was a one touch concept. Correcting the brightness/contrast was more of a chore, particularly if you happen to be working with more than one layer, this becomes an issue, and not explicitly what it was made for, since it will fail to account for any transperacy.
