Which tool you find best in Adobe Photoshop??? That you think works better than any other tool in any other similar software.
The thing unique to Photoshop that I most appreciate are the smart layer filters. I can apply levels and colour changes as filters without actually changing the image.
The brushes and color correction (management) features in PhotoShop are quite good compared to other photo editing tools. I can be assured of professional results in a streamlined workspace.
i like layers,filters and rendering stuff which is sometimes useful, i even use some 3rd party tools for photoshop
I mainly just love all of the short cuts. Research how to use them and you will increase your speed significantly -cf
