CONTINUED – Examples

Let us see the effects of SHAREN and STRUCTURE on real photos.

Please watch them while comparing both effects carefully. Light gray line effect appears at the edge on SHARPEN result. The brightness level of dark area around edge such as shadows is darker on STRUCTURE result.

Example 1. CHARACTERS

Original photo: Wall at Sagrada Família in Barcelona, Spain
STRUCTURE result : Dark parts such as shadow of characters became darker
SHARPEN result : Light gray line around edges of characters can be seen

Example 2. HAIR STRANDS

The original photo : brown, light brown, and blonde hairs
STRUCTURE result : Shadow between hair strands became darker. Its effect is like CONTRAST.
SHARPEN result. Details around brightest parts such as shine on hair strands can be seen clearly.

Example 3. FOODS

The original photo : Ramen noodle
STRUCTURE result : Shadow and soup color became darker
SHARPEN result : Shine on the soup became brighter. I set a maximum value of SHARPEN to show you the effect clearly

Example 4. FIGURES

The original photo
STRUCTURE result : Black level became darker
SHARPEN result : light gray line effect appeared at the border of figures

Example 5. Golden Buddhist Statue

The original photo
SHARPEN result
SHARPEN result : : The effect looks an aura of the statue

SUMMARY

Can you see the difference clearly? Let us summarize the sharpness functions. From left to right: the original photo, STRUCTURE result, SHARPEN result.

Hannya Mask

You can see clear photos on both SHARPEN and STRUCTURE results. STRUCTURE lowered the brightness of dark colors such as shadows as a result the photo have a contrast. SHARPEN adds light gray line effect as a result, the photo became shinier such as shine on the mask.

Let us summarize the Sharpness functions.

SHARPEN

It makes your photo shinier

STRUCTURE

It makes your photo clearer and produces a contrast

I explained the difference between SHARPEN and STRUCTURE. However, in reality we need to improve our photos using both functions. Please see below.

This is a Ginger Ale with Samurai design photo

From left to right: the original photo, STRUCTURE result, SHARPEN result
SHARPEN & STRUCTURE result

You can see the Samurai clearly on SHARPEN & STRUCTURE result because of the powerful contrast around edges. There is a big difference between black color background and light gray outline of the Samurai. STRUCTURE lowered the brightness of black color more and SHARPEN added light gray line effect at the boundary of the Samurai. As a result, we can see clear edges at the boundary of Samurai and see whole photo clearly.

You can see the powerful improvement. SHARPEN increases shininess around edges. In contrast, STRUCRURE darken around edges. They implement each other and produce a big gap in brightness level around edges.

Hope you can understand Sharpness deeply.

Enjoy!
