Digital arts 18 - Drawing - Flower man

After learned how to use tools like Gimp, Inkscape and GMIC and etc., I hurried for my ultimate goal. It is to create some drawing with these tools. So I started to make my first creation. As green to the world of digital arts. I used very simple tools in Inkscape to create simple linear figures to include part token out from my previous work to form the flower man. The background was drawn in Inkscape and brought into Gimp and applied the Fractalize filter of G'MIC on it and then blurred with Guassian blur filter. The outcome looks like drawing of little kid, but I do like it. Drawing is fun.

Digital arts 17 - Attempt to fix wrong focus

It is clear that the photo did not focus on the bird in the center but the leaves above. Of course, it is due to the auto-focusing system selected the object not intended by the photographer.

Attempts were made to correct the wrong focus problem. Most of the bird was selected by using the magic wand and the selection was copy to a new layer. The layer was then turned to gray scale and set to multiply mode with opacity 75%. A modified image was obtained and seemed to be improved.

More attempts were made to improve it with different filters and layer modes combination. finally, the Drawing filter under the sub-menu Sketch of Script-Fu was use to produce a new layer and set to Multiple with opacity 70% and merged down with the improved layer.

At last, the differences among these photos are not much.

Digital arts 16 - Playing with blurry photo again

As results of the disappointing auto-focusing of my point-and-shot camera, I have many blurry photos to play with. Practices make perfect. So, I have to practice more in order to improve my skills.

光隨影集第八十集 ─ 城門谷玉蘭美

今早晏起，就近到城門谷公園散步。喜見有幾株玉蘭花滿枝頭，十分可人。城門谷公園自栩有春玉蘭、夏荷、秋玫瑰和冬山茶四季芳華，事實上玉蘭、玫瑰和山茶在公園內的開花時間是十分接近，可以說是重疊的。所以，今天玉蘭樹下還襯托着不少山茶和玫瑰，更有近年人氣很高的黃鐘木，普遍栽植的巴西野牡丹也在展示芳姿，勒杜鵑自然也要顯現本土的力量，花壇上也剛換上悅目的鏽球花，真的令人眼花撩亂。有空的話，去看看花，拍拍照，誠賞心樂事也。
