Error configuring application listener of class Log4jConfigListener

SEVERE: Error configuring application listener of class org.springframework.web.util.Log4jConfigListener

In most cases, the described problem is caused by an error inside the application contex file (the applicationContext.xml file, or xxx-servlet.xml.) For instance, a bean definition contains a property that does not map to a setter on the actual class, a “property-placeholder” points to a location that is not found, or, the XML itself is invalid, etc. Unless you configure Tomcat logging to output Spring log statements, you won’t see the details.

Advanced sharpening techniques

November 6, 2011 at 5:51 pm · Filed under Photoshop

1. Duplicate the background layer and set the blend mode to Overlay. Select ‘Overlay’ from the blend modes menu in the layers palette.

2. Choose Filter > Other > High Pass. Increase the pixel radius until you achieve the correct amount of sharpening. A pixel radius of 1.0 if printing to Gloss paper and 3.0 if printing to Matte paper would be about normal.

3. Click on the Foreground color swatch in the Tools palette to open the Color Picker. Enter 0 in the Hue and Saturation fields and 50% in the Brightness field to choose a midtone grey. Select OK. Paint the High Pass layer to remove any sharpening that is not required, e.g. skin tones, skies etc. This technique is especially useful for limiting the visual appearance of noise or film grain.

Photoshop Easy Facial Retouching

November 6, 2011 at 4:12 pm · Filed under Photoshop

  1. Duplicate the Background layer. On the new layer go to Filter > Blur > Gaussian Blur. Enter 10 for the radius. Hit OK. Set the layer’s blending mode to color. Double-click on the layer to the right of the name to open the blending options. Under Advanced Blending, uncheck the R and the G. This makes the layer only affect the blue channel no matter what we do to it. Now go back and check out the blue channel. Looks better.
  2. Create a new Curves Adjustment layer at the top of the layers palette. Now I will use Curves to balance the color in the image. I suggest using Curves over Levels for everything. Curves just gives you much more control.
  3. Create a new blank layer just above the background copy. Select the Healing Brush (J) and make sure that “Sample All Layers” is checked on the property bar. Paint over those spots to remove them.
  4. Select the three layers below the Curve layer. Drag them down to the New Layer button to duplicate them. Hit Command+E to merge the three duplicates.

    Select the Polygonal Lasso Tool and click around her face until all the skin is selected. It doesnt need to be too neat. Now go back, and while holding Alt, click around and deselect anything that is not skin like the eyes, eyebrows, lips, and nostrils. Go back once more and deselect any areas of detail that need to remain, like the edge of the nose, her dimples, her collar bones, and the edge of her chin. This is what my selection looks like as a quick mask:Hit Shift+Command+I to invert the selection and then Delete to delete those pixels. You won’t actually notice a change because the layers below are the same as the layer we are working on.

  5. Go Filter > Blur > Gaussian Blur. Enter 20 for the Radius. Set the layer Opacity to 75%. Select and duplicate the same bottom three layers just like we did before. Hit Command+E to merge them. Put that layer just above the blurred layer. With the new layer selected, hit Command+Alt+G. This creates a clipping mask, which is indicated by the arrow pointing down on the layer. This means that the layer on top will use the bottom layer’s transparency as a mask.
  6. With your new layer still selected, go to Filter > Other > High Pass. Enter 4 for the Radius.Now you can really see how that clipping mask is working, but not for long. Set the blending mode of the layer to Linear Light and set the Opacity to 40%. Done!

Distinguished Paleness


				

				June 4, 2011 at 3:23 pm				· Filed under Photoshop												


				

									
For a distinguished paleness, copy the background layer and set its blending mode to “Screen.” Use Image → Adjustments → Desaturate or “Black & White,” then “Shadows/Highlights” to increase the effect. The exact adjustment options can vary according to your image content.

The effect will cover the entire image unless you click on the “Create Layer Mask” button while holding the Alt/Option key, and then paint the pale areas with the brush tool and white color. You can control the effect’s strength with the opacity slider.

Easily fake an HDR effect


				

				June 4, 2011 at 2:23 pm				· Filed under Photoshop												


				

									
[ 1 ] We’ll call the original layer “ORIGINAL”, now duplicate ORIGINAL and place it above that layer. (We’ll call this “BLACKWHITE”)


[ 2 ] Change the Blending option of BLACKWHITE to “Overlay”


[ 3 ] Go to Image > Adjustements > Desaturate (SHIFT + CTRL + U)


[ 4 ] Now invert BLACKWHITE: Image > Adjustements > Invert (CTRL + I)


[ 5 ] And add a gaussian Blur to it (Filter > Blur > Gaussian Blur) around 40 pixels (This causes the so called ‘bleeding’ of the edges, tweak the amount to personal likings)


[ 6 ] Now duplicate ORIGINAL and place it above BLACKWHITE, name this layer “LINEAR_LAYER”


[ 7 ] Change the blending type of LINEAR_LAYER to “Linear Light”


[ 8 ] Give LINEAR_LAYER an opacity around 62%. And you’re done (For better results, tweak this percentage)

Dodge And Burn Look


				

				June 4, 2011 at 2:22 pm				· Filed under Photoshop												


				

									
Start with your image, copy the layer twice with ctrl + j.


Then set the blending mode of the top copy layer to “Vivid Light”.


Use Control/Command + I to invert the top layer content, and apply Filter → Blur → Surface Blur with a radius of about 70 pixels and a threshold of 40 levels.


Now flatten this layer and the untouched 1st copy together, leaving base layer as original image. Set the blending mode of the combined layers to overlay.


Apply a “Gaussian Blur” of 1px -2px to make the contours a little softer,


and then click Image → Adjustments → Desaturate, if you prefer flatter colours.

Reducing Noise


				

				June 4, 2011 at 2:20 pm				· Filed under Photoshop												


				

									
Copy the background layer by pressing Control/Command + J, switch to the Channels palette, and select the channel that shows the least noise. Drag that channel down to the “New Channel” icon (next to the trash can) and go to Stylize → Find Edges. Then apply a Gaussian Blur with a radius of about 3 pixels.


Click on the new channel’s miniature icon while holding the Control/Command key to select the content. Activate the “RGB channel” (top-most), and switch back to the Layers palette. When the duplicated background is selected, click on the “Add Layer Mask” icon.


Click on the Layer Miniature icon, and select Filter → Blur → Surface Blur from the menu. Play around with the Radius and Threshold sliders until the noise has been reduced as much as possible. Thanks to the mask you created, the contours are safe.
