Thanks I've managed it now. Had to use photoshop to crop my images then I found out there's a series of frames in Canva which did the layer mask type thing I was after. Thanks anyway!
I’d like to help out but I have never used Canva so it’s hard to understand the process or the final effect you’re after. If you need to make a gradient in PS and use it in other program then that’s easy enough. Perhaps you want to show a final image you desire to achieve?
Can anyone help with this one?
