Sometimes when editing a photograph, you might want to add some radial filters… but you don’t want them to really stand out… you just want a hint of light.. For instance take this photograph.
I didn’t want to add too much light in places, just subtle hints.. but the problem is after adding a few radial filters… and with each radial filter being given such a small exposure value my eyes become accustomed and I couldn’t see how much of an effect I was creating.
When the white square is at the bottom the effect is off… So in my case with the above photograph once I put the Radial Filters to the OFF position I could see the changes of my radial filters by flicking the little icon on and off.
You can also use the ON and OFF button for all your adjustment tools except the Crop Tool
As well as the different panels within the Develop Module should you alter any of the sliders… Take for instance the Effects Module, where you have added a vignette…
By clicking the Button to the OFF position on the Effects Panel.
Here is the photograph without the Effects added.
