My preference is for the B&W one sheila. Tinting filters (Corel Photopaint) and Sepias seem different from color filters in how they add colors. Intuitively I go for the slow color slide effects of tints first off. The psychadelic style Photoshop color changes can work but the secret of natural color change is to 'see' color saturation and tone as a fine tuning device. I don't know how to explain this, it is a 'that feels right and too much is overkill type sensitivity' Photoshop can radically alter images quickly but I think it takes practice to really master them. Like the piano... practice, practice, practice... have fun!!!
