anyone have a photoshop primer?
Here's one I wrote on another forum regarding this pic I did:
Pic of my miata
Original
My workflow isn't too formulaic, but the general concept of it is to get the main subject in focus by minimalizing distractions.
I generally try to achieve this by the manipulation of lighting and color. In the original miata pic, the sky was too bright, and the car was too dark. There were colors everywhere that distracted from the scene and didn't blend well. So basically, for your image, you want to figure out what's distracting the main subject in the picture.
1. To manipulate the lighting of an image, the blending modes in photoshop are REALLY powerful for this. You could very easily darken the lighting just by using the paintbrush tool with the soft light or overlay blending mode, and black as the color. Furthermore, you can add red lighting by using a red paintbrush or blue color with the blue paintbrush.
The gradient tool on the overlay/soft light very useful to seamlessly and quickly change the lighting. For example, the most simple black to white gradient can allow you to darken one side of the image while lightening up the other side. So in the case of my miata pic where the sky was too bright, and the car was too dim, just using this tool would instantly bring the car out of the picture, and subdue the bright sky.
Furthermore, you can change the color intensity just by duplicating the original layer and setting the blending mode to softlight/overlay. This works since you're basically casting a light that's identical to the picture. I also like to use this to increase the contrast. Use curves on the new duplicate layer to fine tune the contrast. Another great thing with this is that you can just the burn tool to darken objects that you find that are too bright, or the dodge tool to brighten up things that are too dark.
2. To selectively manipulate certain colors an image, I find hue/saturation and selective color to be the most useful. In the miata pic, I desaturated the green with the hue/saturation by selecting green from the menu, and using the eyedropper tool to color sample a patch of grass.
I used selective color to color balance a specific color. For example, if I find the shade of blue a bit too green, I can neutralize it by using selective color.
3. Local contrast. Here's a guide that talks about it indetail
Basically you use unsharp mask with a high radius. This really creates a lot of pop in your images. This technique was really powerful in giving the cars a high luster shine.
4. Depth of Focus. This one is really optional, but it's a quick way to subdue the backdrop. It's hard to get it to look genuine though, so I generally don't use it.
To bring things out of focus, Lens Blur is obviously the best choice.
I generally just duplicate the original layer, and lens blur the whole image. Then I use the eraser tool to get the subject back in focus. You want to make brush size of the eraser tool very big with minimal hardness in order to get a smooth transition between blurriness and non blurriness.
Don't worry about erasing too much of the blur. You can then go back and fine tune it with the history brush tool.
So that's basically it. It mostly just boils down to lighting and color. You really just have to play with the tools in photoshop, and to tinker with different settings to taste. But the goal of retouching a picture is quite simply to bring the main subject out as the primary focus of the picture.
