Adobe Tutorial

1. Select Background layer in layers palette
2. Select the complete eye area ( including the white part ) using any selection tool (i used quick selection tool). Right click over the selected portion and say Layer via Copy. Name this layer in layers palette as Eyes by double clicking the layer in the palette.
3. Now select the background layer again and make a selection for the eye ball regions only. And right click and select Layer via Copy and name this layer as Eye ball.
4. Now Conrol+Click on the layer Eyes to show the eyes selected in the image. Click on Background layer and Select Inverse from right click on image area followed by Layer via Copy. Name this new layer as Blur. This constitutes the whole image except the eye region.
5. Now select the layer Blur and Filter>Blur>Gaussian Blur. Modify the blur to something like 2.5 or lesser. This is done to rest of the image leaving eyes so that eyes are prominent in the image. Click Ok. You can later on modify the opacity of the layer making it more transparent if you want to decrease the blur effect. You can do that by selecting this layer in the layer palette and moving the opacity slider on right top of layers palette.
6. Now select the layer Eyes. Go to Enhance>Adjust Sharpness. Now make changes to the amount and radius. Click Ok. You can vary the sliders as per your needs and preview it side by side in image area or preview area in the dialog. Do not oversharpen as it makes the eyes look artificial.
7. Now select only the layer Eye ball and select Enhance >Unsharp mask.
I changed the amount to near 50% and radius to near 16. This details out the pattern inside the eye ball and brings more focus to the eye region.
8. You can now also increase the saturation of this layer by Enhance>Adjust color>Adjust Hue/Saturation. You can select the Grrens from the combo box if you obly want to saturate the Green of the eyes using the Saturation slider.
Click Ok.

Here are the initial and the final images :

Make a photo more contrastive

This tutorial will show you how to turn a normal image into a contrastive one!

Step 1: First download the original photo below:


Step 2: Next we use some popular tools to adjust its contrast and brightness like Curves tool (Image>Adjustments>Curves)


and Color Balance (Image>Adjustments>Color Balance) with these settings:




Our photo now looks like this:


Step 3:Duplicate your photo (Ctrl-J) and go to File>Blur>Gaussian Blur and choose a radius of 2 pixels to blur this layer a bit


Step 4: Then from the Layers tab, change the blending mode of this layer to Soft Light


And your photo will become more contrastive like the photo below:


This method is commonly used to emphasize something you want on a photo by making it more contrastive with the background. The model now looks lovely and lively!

First, Select the picture that you want to make more clearly.
This is my picture, Its not good :


1. Before do anything, for safe, we create other layer by Press CTR + j to Duplicate Layer .



2. Use Filter -> Sharpen -> Unsharp Mask. In this step, we make a picture more clear.
With parameters:
Amount : 75 %
Radius: 1.5 pixels
Threshold: 0 levels

3. Next, we use Filter -> Blur -> Surface Blur. As follow:
Radius: 10 pixels
Threshold: 10 levels

We have result of 3 steps above:



Then, we will use 4 tools of Image -> Adjustment: Brightness/Contrast , Color Balance , Levels and Curves.

5. Brightness/Contrast: with parameters
Brightness: -5
Contrast: +5

6. Color Balance:
Check Preserve Luminosity (if it is unchecked)
Select Shadows and set parameters into Color Levels: -25 -5 -7
Select Midtones and set parameters into Color Levels: -15 +11 -31
Select Highlights and set parameters into Color Levels: -5 +5 +5

7. Levels (or CTR + L)
Channels : RGB
Input Levels: 6 0.88 235
Out Levels: 0 255

8. Continue with Levels:
Channels : RGB
Input Levels: 0 1.00 255
Out Levels: 0 245

9. Curves: You set as figure :
First, with Channel: RGB



Channel: Red



Channel : Green



Channel : Blue



10. Final, we have a new picture

While debates continue over which of Photoshops two main sharpening filters is better, "Unsharp Mask" or the new (as of CS2) "Smart Sharpen", one method of sharpening images remains not only highly effective but also much easier to use than either of those sharpening filters, and thats by using Photoshops High Pass filter.

The reason the High Pass filter technique works so well at sharpening images is because any areas in the image which are not an edge are left untouched. The only areas that have sharpening applied to them are the edges, which is exactly what you want, and also what all of those confusing options in the "Unsharp Mask" and "Smart Sharpen" filters are trying to help you achieve.

With the High Pass filter, you can often get better results than either of the sharpening filters can give you without fumbling around with confusing options. In this Photoshop tutorial, well look at how to use it.

Heres the image Ill be using for this tutorial:



Heres how it will look after sharpening it with the High Pass filter:



Lets get started.

Step 1: Duplicate The Background Layer

The first thing we need to do is duplicate the Background layer, so Ill do that using the quick keyboard shortcut Ctrl+J (Win) / Command+J (Mac). I can see in my Layers palette now that I have my original Background layer at the bottom, which contains my original pixel information, and the duplicate of it, which Photoshop automatically names "Layer 1", above:



Step 2: Change The Blend Mode Of The Duplicate Layer To "Overlay"

Next, we need to change the blend mode of the duplicate layer from "Normal" to "Overlay". The reason is that the High Pass filter is going to turn all non-edge areas of the image into neutral gray, and the Overlay blend mode leaves all neutral gray areas alone, which means no sharpening will be applied to any of those areas. So to do that, go up to the Blend Mode options in the top left corner of the Layer Styles dialog box, click on the down-pointing arrow to the right of the word "Normal", and select Overlay from the list:



Your image will now appear to have way too much contrast, as we can see here with mine:



Dont worry, its only temporary. Were changing the blend mode now so that we can see a preview of our sharpening being applied with the High Pass filter, which well do next.

Step 3: Apply The "High Pass" Filter To The Duplicate Layer

Now that we have the blend mode set to Overlay, which is going to allow us to see a preview of what were doing, we can apply the High Pass filter. To do that, go up to the Filter menu at the top of the screen, choose Other down near the bottom, and then choose High Pass. This brings up the High Pass filter dialog box:



Photoshops High Pass filter is very simple to use. It has a slider bar at the bottom to increase or decrease the intensity of the filter (the "Radius" value), as well as an input box if youd prefer to type a value directly into it, and thats all there is to it except for the large preview area and the "Preview" checkbox in the top right corner. Definitely much simpler than "Unsharp Mask" or "Smart Sharpen".

To sharpen your image with the High Pass filter, keep an eye on your image in the document window and adjust the Radius value by dragging the slider bar left or right. As you drag towards the right, youll be adding more sharpening, and as you drag to the left, youll be reducing the amount of sharpening. Youre going to want to start off with a very low radius value, somewhere between 2-5 pixels, and even that may be too much depending on the pixel dimensions of your image. Im using a small version of the image for this tutorial, and I can already see that 2 pixels is too high. If you go too high, youll begin to see a halo effect around the edges of your image, and you want to avoid that, so back off on the radius value by dragging the slider bar to the left once the halos begin to appear.

For my image, and again Im using a small version of the photo for this tutorial, Im going to set my Radius value to 1.2 pixels, which gives me a nice amount of sharpening around the edges in the image without sharpening any non-edge areas:



Heres my image after sharpening it with a radius value of 1.2 pixels:



If youre working on a larger image, which you probably area if the image came out of your digital camera, youll most likely end up using a higher radius value, but again, dont go too far. Lower pixel values work best.

Theres a couple of things we can do now to fine-tune the sharpening, which well look at next.

Step 4: Change The Blend Mode To "Soft Light" Or "Hard Light" If Needed To Adjust Sharpening

Now that weve applied our sharpening to the image, one of the ways we can fine-tune it is by changing the blend mode of our duplicate Background layer. Right now, were using the "Overlay" blend mode, which is sort of the "average" amount of sharpening. If you want to increase the sharpening amount, go back up to the Blend Mode options in the top left corner of the Layers palette, click on the down-pointing arrow to the right of the word "Overlay" and change the blend mode to Hard Light:



If you want to reduce the amount of sharpening, change the blend mode from "Overlay" to Soft Light, again by clicking on the down-pointing arrow in the top left of the Layers palette and selecting "Soft Light" from the list:



For comparison, heres the same image using all three blend modes to adjust the sharpening. The image on the left is using Soft Light, the one in the middle is set to Overlay, and the one on the right is set to Hard Light:



The difference may not be easy to see on your monitor with these low resolution images, but if youre working on larger images, the difference between the three blend modes will be more apparent.

Step 5: Reduce The Sharpening Amount By Lowering The Layer Opacity

Another simple way to fine-tune the sharpening is by adjusting the duplicate layers opacity value. Lowering the opacity value will reduce the amount of sharpening. Youll find the Opacity option in the top right corner of the Layers palette, directly beside the blend mode options. Im going to set my blend mode to Hard Light and then lower the opacity of the layer to 80%:



Here, after lowering the opacity, is my final result:
