It is very easy. I know, most of you know how to do it. But may be some of you find something new in this tutorial. Let’s start. Open your photo that you want to re-size and adjust for web.
Step 1 – Manual Levels adjustments.
In this step we will make the image more bright, contrast and crisp.
Image ->Adjustments -> Levels
Level adjustments in Photoshop
This tutorial is not about using levels in Photoshop, so if you don’t know theory, but want your photo looks good, this is an universal solution. This idea works good if you have a correct white balance on your image.
Simple move sliders to both ways on 5 points starting with color channels and finished in RGB.

You can see before and after your adjustments by clicking check box “Preview”
Step 2. Re-size the image
Image -> Image Size -> Pixel Dimensions (for example width 600)
Don’t forget to choose Bicubic Sharper (Best for reduction)

Step 3. Sharpening photos for web in Photoshop.
There are many different ways to get sharp clear images. I will show you only two basic methods.
First – Unsharp mask
Filter -> Sharpen -> Unsharp Mask
Unsharp mask
I apply these settings (use it for most images):

Unsharp mask settings
Check and uncheck “Preview” to see changes.
Second method is Filter “High Pass”
Duplicate layer. Change the Blending Mode of this new layer from “Normal” to “Overlay” from the drop-down box.

Change normal mode to overlay
Remove saturation on this layer. Image -> Adjustments -> Hue/Saturation

Remove saturation
Apply The “High Pass” Filter To The Duplicate Layer:
Filter -> Other -> High Pass.. (I prefer Radius value 0.2-2)

Use the Opacity slider on the High Pass layer to adjust the effect as desired.
Step 4 Mark your image with your Signature or Copyright
Step 5 Save your photo for web
File -> Save for Web & Devices

Save photo for web
I save my pictures as JPGs, usually 68-75 quality.
Then click the “Save” button, type a file name, browse to the desired folder on your computer and click “Save”. You now have an optimized, web-ready photo.
