step1 analysis poster
When we start designing the poster effect, we first look at the Sin City movie poster and know what we need to do to achieve this effect, such as "what makes him look like a (mysterious, horror, fairy tale, comic, etc.) effect" ? ” “What colors, contrasting features, type and composition, more effects will be used? ” etc.
We see there are black/white images, with high contrast halo effects still raining down!
There are also many special effects, mainly most of the White Sin City logos
Some pictures in the poster contain black and white effects, and some pictures are pure black and white effects. In the poster tutorial, we will use pure black and white effects.
Step2 converts to whitening effect
First create a new layer for the black and white effect, press CTRL-J (this will duplicate the background layer) and name the new layer black and white. We need some contrast and retain some details for the black and white effect. Let's look at the channels (press CTRL-1, then CTRL-2 and CTRL-3 to view the R, G and B channels, and finally CTRL ~ back to RGB). Among the channels, the most contrasting ones are red and green, blue The color channel effect is slightly worse. In order to make good use of the red and green channels, we use the Channel Mixer, select Image>Adjustment>Channel Mixer, your settings are as follows, you can also experiment to achieve the effect you are most satisfied with.
step3 changes day to night -1
To switch to night, we have to first invert the sky constituency. Select the sky using the Magic Wand Tool (press w). If the opportunity is good, you won't have to choose too much. Select the Rectangular Marquee Tool (press M ) then hold down the ALT key and deselect unnecessary areas. After selecting, press CTRL+I to deselect the sky. The sky will turn black. Cancel (press CTRL-d).
step4 turns day into night -2
We already have a black sky, but there's still some sunlight on the roof. Don’t worry, I will teach you how to use the real skills of PS to use the burn tool and press O to darken parts of the image.
