[Note Guidelines] Photographer's Note
Another picture from Lake Louise from my Canada trip last year.

One question to the TE members: The sharpness of my pictures is OK, but when I reduce the size for uploading to TE they are not sharp anymore. The size of the pictures is reduced by Photoshop. How do you avoid this????

Hello Andreas,
Beautiful image. Good choice to take the stones first.
I would have removed a bit more of the top, we don't need to know that is was cloudy that day. Nice colours too.
Re. the size, I modify my pictures on Gimp. I first choose the size and I can size increase the quality up to 200kb. You can certainly do the same on Photoshop and someone will probably tell you in a few minutes!

Hi Andreas,
Oh,sharpening...that is a problem:)
Generally speaking, sharpening should be the last operation you do for your photos, even after resizing for web.
I usually do it before resizing for web, when the image is still at full size.
Then I resize it to 800 pixels and I do it again, because the images softens when is being resized. For the small size image I use the following settings for the Unsharp Mask:300/0.2/0.
This is how I do the sharpening:
Method one, in RGB Color Mode:

1. I duplicate the background layer and set the blending mode to "Luminosity”. Let’s name this layer "USM Sharpen".
2. I make another copy of the background and set the blending mode to "Darken". I will name this layer "Remove white halos”. Make the layer invisible by clicking the eye aside of him.
3. Apply the Unsharp Mask filter to the layer in the middle ("USM Sharpen"). For the settings go for the maximum, let`s say 500/0.3/0.Now the image will look way too over sharpened.
4. Make the upper layer ("Remove white halos") visible. Now the image will not look sharpened at all because this layer isn`t sharpened and its opacity is still at 100%.
5. Reduce its opacity until the image will look sharp but not over sharpened.

Method two, in Lab Color Mode.
This is a superior method of sharpening because you only sharpen the lightness channel, which carries all the detail information.
1. Convert the photo to Lab color mode.
2. Duplicate the background layer
3. Select the Lightness channel (Press Ctrl+1)
4. Apply the USM
5. Convert the image back to RGB and for the web, to sRGB.
6. Done.
I hope it helps. If not, give me a shout and I`ll send you more detailed info.

Hallo Andreas,
Top-Bildaufteilung und Proportionen.
Ein kleinerer lebendigerer Teil und eine größere einheitlichere Fläche ergeben immer ein spannendes Ensemble. Sieht man oft in abstrakten Kunstwerken.
