Photoshopping Canada’s Ice Hotel #9 Peter Greenberg Worldwide Share post Share post Under the B tab, I boosted the Contrast and Blacks, changed Color Temperature to 4300 to “cool” the colors, boosted Sharpening to 100 and set Luminance and Color sliders to 30. I created the warped effect using Photoshop’s Warp feature. Text & photos by Rick Sammon
