Hue/Saturation

[SandyDiVa]

I’m very new to the app, just leaving PS for iOS.
In
PS I’d select with the lasso tool then choose hue saturation and only the lassoed area would be affected.
In this app, even though only a small area is selected with the lasso, the entire image changes! What an I doing wrong? please help!

i am using ArtStudioPro 2.3.27(530) on iPhone8,the situation you mentioned could not show up.In my App,everything is ok,only the content inside the lassol tool is changing by adjusting these hue/saturation parameters.

Remember:Every bug report without mention its version is NONSENSE.

If you use adjustmnet layer - it will be applied to the whole layer. You can also limit it using Layer Mask.

To quickly apply any adjustment tap for example Adjust > Brightness/Contrast in the top menu. This will work with the selection
