Whenever I add a photo filter to an image, I can't use the sampler tool that automatically appears when you open the photo filter dialog box to manually select the color of your filter. Whenever I try to use it, it automatically selects white (#ffffff), no matter where I click in the image. Does anyone know what I'm doing wrong?
When you add an adjustment layer, the layer mask is automatically active. You need to activate the pixel (image) layer by clicking on it in the Layers panel.
