which iPad are you on?
I Pad air
I Can select the fx pair brush tool and then i select pencil as the effect and then touch the photo and its all changed to pencil but it does not save and then goes back to the picture and then just when you think you might be able to draw the peculiar effect on the photo then nothing when you touch the iPad .... Noting happens to the photo...
So just to be sure, once you have selected the effect you press the ok/checkmark button and start painting over the image.
Does restarting the application help?
If not - does restarting the device help?
OOnce I start painting over the image I get nothing it does nothing incan see a circLe that represent the brush head...and I run it over the area that I want to change...and then I get the program thinks with the boxes like it thinking to do it but nothing happens at all. It does not make any changes at all... Even when I save it no change... The eraser works but not the effect festure... feature.... YYes I have restarted the iPad nothing changes I really need this featuressap....
How many layers do you have btw?
Have you checked the settings in the brush, opacity, size e.g.?
Exactly what iOS version are you using?
Have you tried to quit all other running applications and then restart the app or device?
It can be that its by some reason is low on resources if this isn't a brush thing.
version iOS 8.1.1
as I said the latest versions
jjust one layer btw
YYou I can see the brush size yes I have checked it ... I just quit all other application and restarted photoshop
