image combination and creation - the power of photoshop

Posted by Jen in design & art, tutorials on May 30th, 2009

I’ve been amazed by the special effects created in Photoshop for a long time, and this time I would like to make one by myself.  Steps are as follows:

kevin_originalimage 1: boy and ground
layer mask to select the part of the boy and ground that I want. and clone stamp to create the ground and ground edge.
shadow/Highlight was used to correct the brightness of the image. use the sun image as the color match source file, to apply it to boy and ground.
seaimage 2: sea
free transform to stretch the pic and get rid of the sun. save it as the displace map. render light to the sea. and do displace of the sun shine. reflection of the clouds on the left side of the sea surface, filter used is motion blur and blend mode is softlight with opacity 20%.
sunsetimage 3: sky and orange clouds
clone stamp to create part of the sky and get rid of the mountain. Free transform, perspective and scale to have more depth and to get rid of the mountain and composite with the sea.
crystal_ballimage 4: crystal ball
techniques used: inner shadow, inner glow, linear gradient, sphere distort, hard brush, soft brush, square to polar distort.
sunimage 5: sun
techniques used are as follows:filters: render clouds, render difference clouds, find edge;
image adjustments: levels, hue & saturation;
blend mode linear dodge.

FINAL IMAGE - the enlightened universe:

enlightened_universe_final

Gestalt is well accomplished in here. I separate the image into 5 objects: the sky with orange clouds, the surface of the sea, the boy and the ground, the fake sun and a fake crystal ball. The first 3 are from photos, the last two are made up by myself with Photoshop techniques and tools. Now, all the objects look like in one environment.   I was trying to make the image match the color of the fake sun, since it is the shiniest part of the image. Therefore, the tone of the image will be yellowish orange. The theme of the image will be mystery. Sun is abnormally huge, the boy is standing in front of the sun on a high and steep ground, holding a crystal ball, just like a little witch.

There are quite some challenges I met in this project, like the colors of the original 3 images don’t go along with each other, the surface of the sea need to have reflection of the sun shine, etc. Therefore, in this project I would say this biggest effort I made is to integrate the objects to make it look like in one environment, which required the techniques in image adjustment and level adjustment.

Toy Room - Photoshop: brush, vanishing point transform and more

Posted by Jen in design & art, tutorials on May 27th, 2009

With given components of the toys, I designed a 3-D environment (walls and floor and window) and a colorful toy box with shadows and vanishing point, plus a photo frame.

A few highlights of this photoshop creative:

The brush I created is for the surface of toy box.  The original brush is from the Assorted brush set, named concentric circles.  I basically modified its master diameter to 200px and  set the shape dynamics settings: size Jitter to 100%, minimum diameter to 15%. For the colorful background of the toy box, I actually customized another brush from Assorted brushes, called texture 6.  I modified its master diameter to a much larger one and added the color dynamics feature to make it vary in Hue and saturatioin as well. In order to make the white circles integrated into the whole painting, I used the blend mode Lighten and opacity 90%. Then I think the white concentric cirle really goes with the abstract background of the toy box painting.

I am using the CS version, therefore, I created the 3-point perspective all by transforming, without the vanishing point filter. I used the lines as the guide for the perpective, as shown in the image of the perspective box.

I set the environment as a corner of a room with a window on one side. I think this way, it will make it clear to the audience where the light source located. And having a little witch floating outside the window make the picture more interesting. Everything including the window, wall, floor and toys in the enviroment is transformed into 3-D.

The shadows are made according to the light source from the window. As the window is on the left side of the environment, all the shadows are heading toward the right side, except the shadow of the motocyle, because it is leaning on the left side wall, just underneathe the window, its shadow is on the wall.

The first frame is made from the texture of the roof on the house (one of the toys). The 3-D effect (bigger pattern in the middle, small pattern on the sides) are achieved by utilizing the technique of alpha channel. I like this effect, it looks pretty real.

How can you use words and pictures together to improve the unity of a design?

Posted by Jen in design & art on May 27th, 2009

shadow_titleWhen it comes to graphic design, Unity is also referred as Integration, meaning all the elements in the work appear to belong to each other, and make a whole of composition.  This is a very basic and important goal of any graphic design work.  Components in one design work are not supposed to compete with each other or hide from each other but rather support each other in a certain priority order to give a flow to the design to provide messages.

Type and images are two different kinds of elements in the design world, but equally important.  Type comes up with words to tell the message in a direct and straightforward way, while picture gives people more space to portrait it to a certain meaning with their own interpretation. And when we put these two elements together into one work, the design gets sophisticated and being equipped more dimensions. In a lot of design works, types are placed in front of the picture and stands out from the background picture to give a clear view for the audience.  However, there are also works that have type appeared more in an imagery way, by means of extreme dimension of the text and uncommon fonts, which are not so clear for the audience at the first sight to read text message. And in this kind of design, the image elements may in a major role of the work.  However no matter which element takes the lead, unity is always the goal to put them together, in which case, type can convert to image and image can also be shown in a type way (just like the type mask we did).  CONSISTENCY is one of the methods we use frequently to achieve the goal of unity, which include the consistency of color, style, alignment, etc.  Color – we choose a color that appears in the picture (usually appears repeatedly) for the color of the type.  Style – around the theme of story the design is telling, we choose the style of the picture and the font.  Say, the design is telling a happy story, we may use a highly saturated color image with a cheerful-looking font.  Besides that, POSITON is also a very important factor for a unity design.  This involves with the concept in our previous topic – space.  Usually for the type that is placed in front of the picture, we would choose to place it on the portion of the image that has less variety and more monotones, which is also referred as negative space.  Type on negative space can get the effect of not only standing out of the picture but also integrate with it.

I believe there are more principles than the above ones I mentioned to create a unified design.  However, the point is to achieve an integrated composition as we desired, multiple methods and principles need to be applied to one art work than just stick to one.

Sarah McLachlan & Surfacing

Posted by Jen in design & art on May 21st, 2009

Sarah McLachlan is a wonderfully talented Canadian singer/songwriter/musician. At a young age, she was trained at the Royal Conservatory of Music in Nova Scotia. She learned guitar for 12 years, piano for 8 years and spent 5 years refining her voice.

Her success in music leads to numerous awards, which includes: 3 time Grammy Award winner and the Elizabeth Cady Stanton Visionary Award for advancing the careers of women in music. Sarah has sold over 22 million records worldwide since her recording career began with her debut release, “Touch”, in 1988 and has been profiled by media the world over including cover stories for Rolling Stone, Time and Entertainment Weekly.

Her music is featured of her pure voice and beautiful harmonies along with love and loss in a depth of warmth.

song_pr3The disc Surfacing was released in 1997 and come out of nowhere in a time when the teen pop craze was going on. It had sophisticated songwriting with great piano and guitar hooks and Sarah scored some great hits from this record that were in heavy rotation in 1997 and 1998.

I chose the album surfacing to design the CD cover for, because it is such a masterpiece of Sarah. It is a singer and songwriter at the top of her talent. I am amazed every time I listen to this CD. The design of the cover is trying to match the style of “Surfacing”. The black background with Sarah’s initial in dark grey, the type “surfacing” with reflection, and the feathered type of the name in the font of Mistral are all attempting to approach the depth of the music, the meaning of the lyrics and stunning beauty of her voice.

Type - THE element in graphics

Posted by Jen in design & art, random thoughts on May 19th, 2009

Type is a very critical element in graphic design. The principle that applies to other graphic design elements also applies to typography. Those principles include asymmetry, space, contrast, unity, rhythm, emphasis and hierarchy.  However in addition to those common features of all the graphic design elements, typography as a special element has its own unique features.

Type that consists of the same letters can give very different look and feel and thus express very different emotions and convey very different meanings for the entire graphic work. Type can vary with its font, size, weight, capital/small character, leading, tracking, kerning, color as well as position to other type.  There are so many factors that can affect the look and feel of the type.

Among those factors, fonts can affect the type dramatically.  As we know, fonts have various personalities. Some fonts can be used in a very formal and official situation, while some can look very playful and childish; some are classy and stylish, while others are rough and heavy.  For some design works, just by looking at the font, the audience will be able to get a brief idea of what the design is trying to say, even before reading the content.

Due to so many attributes of the type, it can also be used to create visual variation in a composition design work.  Options for variation can be Italic versus Regular, Light versus Bold, Uppercase versus Lowercase, Sans Serif versus Serif, etc.

Special effects added to fonts can also lead to great results. Outline, Inline, Shadow are the ones that have been used regularly in modern graphics.   However, overusing those effects can result in a muddy, illegible message.

To summarize, type is an amazing element in graphic design.  It affects the look and feel of the design dramatically by all kinds of its attributes. To introduce the variation of type into the design, we should also be cautious to avoid too many special effects and variations. Because all the effects are just to support the design to convey a clear message.  Therefore, in most cases, a good design doesn’t have more than 3 types of fonts.

get date string using linux unix shell command

Posted by William in backend on May 17th, 2009

Sometimes you need to use get the date string as part of your shell command. For example, you want to do a daily dump of your MySQL database as backup. You can do that with a cron job. You want the date string as the file name it dumps to. You can do something like as your cron job:

mysqldump -hlocalhost -uroot mydb > /home/john/db_backup/mydb-`date +%Y%m%d`.sql

There are also times you want to do something for yesterday’s activity. For example, you have a daily log of some user activity, and you would like to run some script in early morning every day to process the yesterday’s log so that by morning you have the reports for yesterday. So here you need to get the date string for yesterday.

In this case, you can use the –date option together with +format. For example:

yesterday=`date –date=”1 days ago” +%Y%m%d`; /home/john/my_report_script.sh -log /var/log/mylog-$yesterday.log
