admin — Tue, 25 Oct 2011 15:27:02 +0000

High pass sharpen is one of many sharpen techniques in Photoshop. Pros of the high pass sharpen is flexibility. With high pass sharpen, you can adjust sharpness easily and you can use layer mask to sharpen only areas you want. For more understanding, please follow the step-by-step instruction below.

1. Open your image.

2. Drag “Background layer” over the new layer icon in order to duplicate it.

3. You will get the “Background copy”

4. Go to Filter>Other>High Pass

5. Adjust radius and the acceptable level of radius is around 1-5. You just only slide the bar and see the preview. If you use too high radius, your image will look unreal. For this case, I use the radius of 4.

6. Your image will look like this.

7. Go to the layer pallet and change mode to overlay.

8. This is the original image.

9. After changing to overlay mode, the photo look sharper.

10. Not only overlay mode, there are several mode that you may use to adjust sharpness of photos.

11. Change to “soft light” = soften image

12. Change to “hard light” = sharpen image

13. Change to “vivid light” = sharpen image

14. By reducing the Opacity, you can reduce level of sharpness. Sharpen must be applied to each image carefully. If sharpen is used too much, the photo may not look like the real one. It may look like the computer graphic photo instead.

Change hair color using Photoshop

admin — Fri, 22 Jul 2011 04:31:10 +0000

I have not been writing Photoshop articles for awhile and today I would like to share how to use the Photoshop to change hair color. Let’s take a book before/after photo.

1. Open your image.

2. Select the Magnetic Lasso Tool from a Tool Pallet. The reason that I select the Magnetic Lasso Tool because this tool will help you create selection easily.

3. Draw the Magnetic Lasso Tool around hair. This tool will create the path automatically based on contrast between colors; therefore, you will be able to create selection pretty easy.

4. Draw the Magnetic Lasso Tool around and double click to create selection around the hair.

5. Go to Select>Modify>Feather or press Alt +Ctrl +D

6. Input feather value. I use 10 pixels. This step is to create smooth selection.

7. Go to Layer>New Fill Layer>Solid Color

8. Change mode to Soft Light, then press OK

9. Color pallet will be popped up and you can select color which will be hair color. For this example, I select brown.

10. You will see that you already have the girl with brown hair. However, you need to fix some part of her hair.

11. Go to the layer pallet and select the Layer Mask area

12. Select brush tool and assign white as brush color

13. Adjust its size and opacity. For this step, you may need to trial and error for few times in order to get the right brush size.

14. Please remember that painting white is used to add details. It means that we will paint into some area where hair is not brown yet. On the other hand, painting black is used to hide some details and we use it for some parts which we don’t want brown. For this step, you need to practice using brush and layer mask. There may be few times of trial and error before you get satisfied result. Try to paint until you get a good result.

15. If you want to change colors, you can go to the layer pallet. Double click at the color fill layer

16. Change colors and click OK.

17. This is new hair color.

I wish this tutorial would be helpful for you.

Remove Undesired Spots in Photos with Adobe Photoshop

admin — Mon, 05 Oct 2009 01:54:58 +0000

You may have seen some undesirable points such as hot pixel, flare, dust, etc in your digital photos. These bad spots can be easily removed by using healing tool in Adobe Photoshop. This tutorial will demonstrate you how to remove undesirable spot from your shot.

Photograph info: Location Budhamondhol Thailand.

From the photo above, I took this photo with long shutter speed and you can see that there are some flares and hot pixels in my photo. These unattractive points can be removed easily by using “Healing Tool” in Adobe Photoshop. You can see the example after applying healing tool as shown below.

Click “Healing Tool” on the tool pallet or press “J” to select it.

You can see that there are 4 types of “Healing Tool”; however you need to use only 3 tools as follow;

Spot Healing Brush Tool

Healing Brush Tool

Patch Tool

The last one is “Red Eye Tool” which is used to correct red eye causing by flash gun. Hence, this tool will be skipped from this tutorial.

1) I will start with “Spot Healing Brush Tool” . After you select this tool, click brush property which is at the top right corner to see brush’s property. You can adjust size of brush, hardness, spacing, etc.

Normally, I adjust only the diameter of brush to cover each spot, just a little bit bigger, but for the other properties; I still leave as per default valves.

This is my flare.

Adjust size of brush a little bit bigger than flare and then click where the spots you want to remove. The tool will try to find adjacent color and blend into brush area.

You can see that the flare is gone.

2) The second one is Healing Brush Tool.

Select Healing Brush Tool , click brush property which is at the top right corner to see brush’s property. You can adjust size of brush, hardness, spacing, etc.

I normally adjust brush size just big enough to cover area where I need to remove bad spots.

This is another flare that I would like to remove.

The concept of Healing Brush Tool. is to use color from sample area, which we need to determine, and blend into area where the Healing Brush Tool was painted. You may get confused what this is about. Let’s look at the example below.

Select this tool, hold “Alt” key and click the sample area which should have similar color.

Then paint around the flare as show in this photo.

After that, Photoshop will use blend color nicely so you will see that the flare is gone.

3) The last one is Patch Tool. When using the Patch Tool, you need to create selection area around where you want and drag that selection to area where has similar color. Photoshop will use the color inside selection to paint over your selection.

Let’s see the example. Select this tool and make selection around the flare.

Drag the selection over area which has similar color.

Then Photoshop will do its excellent job as you can see.

Look overall photo (100% zoom) and you may see hot pixel due to long shutter speed.

For these small spot, I would rather use Spot Healing Brush Tool to fix the problem. After I remove all hot pixels, you can see before-and-after photo shown below.

Finally, this tutorial is an example of how to use the “Healing Tool” in Adobe Photoshop to remove some spots. Anyway, the way how to correct undesirable spots of each photo is different but the concept of using tool is the same. Let’s try the Healing Tool to help you remove some undesired spots out of your nice photos.
