How to use the custom shapes with the image modes (RGB CMYK etc) in Photoshop tutorial. You can set Photoshop into number of color modes such as RGB and CMYK and LAB etc and this is done via the image menu and mode and then select the required image mode as well as the color bits per channel such as the standard 8bit or 32bits per channel / 16bits per channel etc for better color. The custom shape can be added to the duotone image. The custom shape can be added to CMYK channels in Photoshop (and separate channels) by changing the image mode to CMYK. You can add the custom shapes in Photoshop to 32bits per channel RGB etc and then use the GDR toning to create amazing color shifts with the custom shapes in Photoshop (such as shapes with fill content of gradients and patterns). All the Photoshop image modes can be used with the custom shapes. You can also change the image mode after you have added the shapes. This tutorial shows you some of the image modes such as duotone image mode in Photoshop as well as 32bits per channel etc and custom shapes added to the mode.
CMYK or 32bits per channel etc
add custom shape via the custom shape tool in Photoshop toolbar
You can add the artwork as a layer or pixel in RGB / CMYK / LAB image modes etc. as well as duotone image mode
image menu and mode and duotone
set type to duotone image mode
set inks such as blue and pink (give them names)
set duotone curve
Simply select the custom shapes tool in the Photoshop toolbar (found normally beneath the rectangle tool but now with the new toolbar customization this tool can be anywhere in the toolbar)
select pixel option for the shapes.
You will see the colors of the shapes never stray from the colors of the inks entered. Many of the adjustment layers and effects are not available unless you return back to RGB image mode
You can add the Photoshop custom shapes / vector layers and pixels to CMYK as well. You can also select the individual channels of cyan and magenta etc and add the artworks to those as well as below where the baubles are added in different locations on the image. Any number of vectors can be added to the image and the color of the vector can be the same or different in the individual channels. You can do the same in 8bit CMYK as well as 16bit CMYK
window menu and channels panel
select the cyan channel
go to the custom shapes tool
select the color and set to fill option
select the custom shape
apply in cyan channel
select magenta channel
apply shape again in that etc
You can also add the Photoshop custom shapes to the image in RGB and 16bit and 32bit mode. You can add them as a layer as well as a pixel in 32bit mode (though not layers in the individual channels). You can also use a selection of effects to combine with the shapes such as the color lookup adjustment.
When you convert back to standard RGB 8bit mode then HDR toning panel appears and then you can tweak the color conversion in numerous ways and create some very subtle color works as well as some truly extreme ones as well as blurry and smooth changes.
32 bits / channel
set custom shapes tool
select custom shape in panel
set to "shape layer"
set the content for the shape fill to gradient and select gradient

go back to image menu and mode and 8bits / channel
modify shape using the HDR toning panel (allowing for all kinds of color manipulation of the shape in Photoshop)
