blending modes of photoshop...

                                                                                        ::LINK COMMAND::

We dont find link layer command in CS and more. Because we can now select more
than one layers and move them, align them.



            ::BLENDING MODES::


Normal:            Default mode.

Dissolve:        Best to use as Brush effect.

Darker:            Compares the two layer. Lighter colors are transparent and darker colors
            are visible. Works best with two different images.

Multiply:        Multiplies the two colors of the two images(layers) and outputs the darker
            color.

Color Burn:        Compares the two layers and Burns/Darkerns each colors to its fullest.   

Linear Burn:        Same as Color burn but it reduces the lightness of the image.

Lighten:        Compares the two colors. Lighter colors are visible and darker colors fade
            out.

Screen:            Compares the two colors and multiplies the lighter colors giving a glow
            effect. Works best for making darker pictures brighter.

Color Dodge:        Multiplies both the colors( shadows, midtones and highlights) leaving a very
            glowing image.

linear Dodge:        Same as Color dodge but it increses the lightness of the image.

Overlay:        Blends two layers(images) nicely calculating its midtones, shadows and highlights.
            Works best for adding textures in faces like scars, burns etc.

Soft light:        Compares two layers(images). Lighter colors are made much lighter and darker colors
            are made much darker as in real life scenario. Good to make shadows.

Hard light:        same as soft light but adds in more light to the resulting image.

Vivid light:        The result of Color burn and Color Dodge.

Linear light:        The result of Linear burn and Linear Dodge.

Pin Light:        Midtones are transparent, Darker and lighter colors are blended.

Hard Mix:        Mixes the two layers' colors to its fullest resulting a unique image high in both
            color and midtones. Black colors are much more visible.

Difference:        Blends two layers comparing the lighter and darker colors. Lighter colors are visible.
            Darker colors are darken resulting a negative kind of effect.

Exclusion:        Similar to Difference but darker colors are not darkened but faded to grayish.

Hue:            Blends with the second layer and tries to increase the orginal color value of both layers
            creating a lighter color overlayed. Doesnt works with black color.

Saturation:        Blends with the second layer and tries to increase the saturation of that particular
            color say red or green. Black and white colors are grayed.

Color:            Tries to color the image with the selected layers color but also blends in the second
            layer. Best with color correction.

Luminosity:        The opposite of color mode, .ie. color the image with the color of the second layer
            but again blends the first layer.






  

about photoshop...

INTRODUCTION:

We usually use Photoshop for image editing, digital painting. Photoshop mostly deals with colors. That is why it is called
as Raster(bitmap) graphics.

 For the editing of a photo at first the page should be selected as per need.
for that such thing should be considered....


1. Pixel:
    Pixels are tiny colored value or also we can say pixels are small dots which contains a color value and its location.
We can see pixels when we zoom any picture element. Pixels are measured as pixel dimension= no. of pixel(height) x no. of
pixel (width). For eg: Pixel dimension 300x300=90,000 pixels.

2. Resolution:
    Resolutions are output quality of any picture. Some used are:
Web layout= 72 dpi
Onscreen  = 96 dpi (100 is the best)
printing  = 150 (black n white) - 300 (color)dpi.







TOOL BAR:

1. MARQUEE:
    Use this tool to select any particular image parts. This is also used for background coloring, banners etc.

2. PEN TOOL:
    Used for selection. While using pen tool press "CTRL+ENTER" to stop at the middle of selection.

4. TO FILL FOREGROUND COLOR IN SELECTED AREA: "ALT+BACKSPACE"

5. TO FILL BACKGROUND COLOR IN SELECTED AREA: "CTRL+BACKSPACE"

7. DEFAULT foreground color is "BLACK" and default background color is "WHITE". To switch to default fg/bg color press "D".

    If you want to apply a foreground, background color to images, goto image>fill. One dialog box appears.
Change the content, blending and opacity as you like and click ok.

    This command will select the back or float portion of any image which is not selected. To use this command:
1. Select an image using any tool for eg. marquee, magic wand, lasso tool.    
2. Press "CTRL+SHIFT+!" or goto SELECT>INVERSE.



NOTE:   Press "]" to increase brush size.
    Press "[" to decrease brush size.
    Press "CTRL+ENTER" for selection.

decrease your document size also.






HEALING TOOL:
    Open a damage photo. Choose healing tool and press "ALT" and slowly by clicking, move your posture.
