The Night Vision Thing


A Night Vision Device (NVD) works by using either image enhancement or thermal imaging techniques. Whichever method is used, photos from night vision devices are instantly recognizable by their greenish glow.


I visited some online stores to study night vision goggles and scopes (research!) and found that images from NVDs also tend to include some noise, some blur, and dark areas near the edges. So I'll incorporate these visual elements into our project to add realism.

Going Gray
Adobe Photoshop tutorialThe first step is to convert your source file to Grayscale. ChooseImage> Mode> Grayscale.

Once in Grayscale mode we can create our night vision green, which we'll do by applying a Duotone.

Two Shades Of Green
Choose
Image> Mode> Duotone.
This will bring up the Duotone Options dialog box. Now we need to pick two different greens. Our Ink 1 green will be 25BF21. Just click on the little color square and enter the number via the Color Picker. You must name your Inks so name this one NVD1 (or whatever you wish). Repeat this for Ink 2 and enter A8D9A7for the color and NVD2 for the name.

We'll go back to RGB mode now. Choose
Image> Mode> RGB Color. Next we'll increase some of the light in the source file.

Tweak With Levels
Adobe Photoshop tutorialCopy your Background Layer and name it. Select your new layer and choose Image> Adjustments> Levels.

In the Input Level dialog box enter (from left to right): 70, 1.00, and230. This will boost the contrast and give us more of a glow from some of the light.

Selective Blur
Choose your
Blur Tool and set it to a low opacity, about 20%. Choose a medium size brush and run it across the bottom of the photo, in this case to make the runway approach lights slightly blurry.

Add Noise
Now we'll add some noise into the file. Choose
Filter> Noise> Add Noise. EnterAmount: 3%, Distribution: Uniforn, and make sure Monochromatic is selected.

Levels - 2nd Pass
Choose
Image> Adjustments> Levels. This time in the Input Level dialog box move the Left Slider toward the right to darken the image uniformly.

Final Adjustments
Choose the
Burn Tool, set it at Midrange, Exposure 50%, and carefully apply your brush in a circular motion to the outside of the image. This gives a nice subtle darkening effect to the edges. Finally choose Hue/Saturation and perform final tweaks by moving the 3 sliders in very small increments.

So Why So Many Steps?
Each NVD photo will come out slightly different because of the specifics of the source file. The point of having so many steps is to give you a chance to tweak the night vision recipe so you can achieve the desired result by experimenting at different key points.

Pixel Fonts To The Rescue



Adobe Photoshop tutorialGraphic designers working on web projects often complain that when typefaces designed for print are set to lower sizes that they become harder to read and unattractive to the eye. Even using anti-aliasing (the smooth option in the Character Palette) is not enough to help these fonts look better on screen. The solution when this happens is to abandon the printer fonts altogether and to try using a Pixel font, which will produce a crisp, clean image at very small sizes.


Pixel Fonts — Limits & Restrictions
Pixel fonts were created specifically for computers, with each pixel of the font designed on a grid that is exactly the same grid that is on your computer screen. Because of this Pixel fonts have certain limitations. They cannot be scaled and must be used at the sizes at which they were designed, or else at exact multiples. This is to prevent them from distorting. It is also important to never apply any anti-aliasing to them.

Let's Pick A Pixel Font
Some great pixel fonts can be found at Joe Gillespie's
minifonts.com site. One of his font creations, Mini 7, is considered to be the most popular Pixel font in use on the web today, and it is one of my all-time favorites.

Pixel Fonts In Action
Pixel fonts are great for website photo captions, because you can get a lot of text into a small area, and it will still be very legible. (The screenshot below uses Mini 7). They are also great for website interfaces, especially navigation buttons.

Pixel Font Troubleshooting Checklist
Adobe Photoshop tutorialFollow these guidelines (from minifonts.com) to avoid the most common problems:
Pixel fonts should be set on a page with a 72 ppi resolution.
Anti-aliasing (font smoothing) should be off.
The type size should be the 'designed size' or multiple of it. You will find this size in your ReadMe file.
All tracking and kerning should be set to zero and character widths to 100%.
Leading (line spacing) can be specified as required.
Always specify your font sizes in pixels, not points. A ten pixel font is not necessarily the same as a ten point one. Change your setup to work in pixels and set your document resolution to 72 ppi (pixels per inch).
Do not use a centered paragraph style. The math required to center text can result in fractional spacing and vertical rows of pixels can mysteriously disappear. Always set your pixel fonts ranged left and center it by moving the whole layer.
Save as GIF images at a 1-bit color depth, resulting in a small file size.

Inspiration
If you're curious as to how far you can take the pixel look, visit
Kaliber 10000 (The Designers' Lunchbox). Now that's a "pixelated" website.

Pixel Fonts — Where To Get Them — Free Font Resources
DaFont.com — DaFont.com has some great free pixel fonts. Just do a search (top right of screen) for "pixel" to find them. I like Snoot.org px10 by Divide by Zero.
04 — On the front page click on "extra" and then you'll see "bitmap font" and "font ps.tt" - which are free downloads. This is a very nice collection of pixel fonts.
Wanted Fonts — Lots of free fonts. On left side navigation you'll see categories. Look for "pixelated" and search through the collection. "Endless Showroom" looks nice.
HighFonts.com — Another nice site with a great collection of free fonts you can download.
Silkscreen - Free Pixel Font — Silkscreen is a free four member type family for your Web graphics created by Jason Kottke. Available in both Mac and Windows versions.
How To Install & Remove Fonts In Windows — This font installation guide will tell you everything you need to know.
MiniFonts.com — Joe Gillespie's site showcases the individual fonts he has for sale (over 200), or you can try the free samples. The site also features some in-depth articles on the history of pixel fonts, pixel font usage tips, and a pixel fonts FAQ page.

How To Resize Images



Adobe Photoshop tutorialYou have a nice big beautiful photo. It is gorgeous. But you need it much, much smaller, and by the time the file is down to the right size, you might find that the image has started to take on a blurry look. This is a real problem with resizing images, but luckily in Photoshop there's a very simple solution.


This tip will only work with Photoshop CS and CS2. If you don't have a CS version yet I recommend you try and get one as soon as you can, because they are full of powerful new features. For earlier versions of Photoshop there's a workaround at the end of this tip.

When you want to reduce an image go to the Image> Image Size menu. Click onResample Image and choose Bicubic Sharper from the drop-down menu. This is the best setting for making sure that an image doesn't blur. The example photo of the flower started at 2,000 pixels across. I stepped it down to 250, and then again to 125 with almost no loss of sharpness. For enlarging an image select Bicubic Smoother.

Adobe Photoshop tutorialI found this to be such an effective trick that I wished it had been the default setting in Photoshop for the Image Size menu from the start. Then I discovered I could set it as the default myself. All you need to do is go to Preferences> General and you'll see Image Interpolation and there you can pick Bicubic Sharper from the choices.

Another thing to keep in mind when resizing is to try to do it only once on an image. Many people will resize repeatedly as they search for the perfect fit for a design element, and then end up with an image with a lot of blur. It's always better to experiment on a duplicate of the image. Then, when you've settled on the final dimensions, you can go back to the original and resize it just once.

Pre-CS Workaround
In earlier versions of Photoshop simply zoom out so that your window and image are at either 50% or 25%, and then take a screenshot of the image window at this new reduced size. You'll find that the image will maintain its sharpness. Now open the screenshot in Photoshop, and crop and save. The trick to making this work is to use either a 50%, 25%, or 12.5% view size before making the capture. If you view the image at 66.7%, 33.3%, or 16.7%, the image will not be as sharp due to the way Photoshop draws images at those sizes.

Photoshop Web Template


Many people new to web design are confused by slices and Javascript rollovers and end up abandoning their projects out of frustration. The point of this Photoshop web tutorial is to keep things simple by creating a web page that uses only 2 graphics.


Website Plan
We'll create a banner and place it in a table that will contain 5 rows and 1 column. The banner will be placed in the top row. The next row will contain the text for your site and any photos you may wish to include. Row 3 will hold a separator, row 4 will be for your text links and a copyright notice, and row 5 will hold a second separator.

Let's Get Going
I'm going to name this site Designer Girlz Network. The next step is to find a graphic for the banner. You might find a good image at one of the free stock photo sites (I've listed some below), but I was looking for something a little more professional, so I tried the iStockPhoto galleries and found an illustration by Vinaya Prashanth that cost only $3. Sweet. That's a reduced version of it on the right.



Choose A Website Color Scheme
The colors of the banner and the website will be taken from the various pinks used in the image. There are 3 pinks I want to use — a dark pink, a middle pink, and a lighter pink that I made myself from a shade of the darker pink.

I find that by using the opacity slider on a sampled color you can create a nice variation. Open a new document and copy and paste the main graphic you've chosen into it. Now from the toolbox select the eyedropper tool and sample a color by clicking on it in your graphic. This will change the foreground color square in your toolbox.



Now open another new document and in the Background Contents select White. Click OK. With this document open, create a new layer by going Layer> New> Layer. Then go Edit> Fill and select Contents, Use: Foreground Color. This will fill your document with the color you just sampled. The trick here is to lower the opacity using the slider and to keep playing around with it until you find a nice shade. When you settle on one, flatten the image by going Layer> Flatten Image. Use the eyedropper tool again, this time to change the foreground color square in your toolbox so it is the same as your newly created color. Now click on the color square and the color picker will come up, and you can write down the numbers of your new color.

Choose A Font
I went through my fonts and settled on Onyx regular. When you find a font that works for you, try playing with the tracking, the leading, and the scale — or a combination. It makes it more personal and unique when you include some tweaks.



To select a font in Photoshop go Window> Character. In the palette you'll see a list of your installed fonts. To tweak the settings you'll need to bring up the Paragraph palette. You can do this by going Window> Paragraph.

Looking for new fonts? At the end of this tutorial you'll find a list to some free font resources.

Designing A Website Banner
Create a new document that is 600 x 300 pixels. You can change this size to suit your own design when you pick your own stock photo and plan the layout accordingly.



Now I'll create a new layer, Layer> New Layer and I'll call it Designer Girl. I'll place the illustration on this layer and shrink it to fit. You shrink your graphic by choosing Edit> Transform> Scale. The bounding box will have handles. Use the Shift Key to constrain proportions, and shrink your image by selecting the top left handle and pulling towards the bottom right. To move the graphic, drag inside the bounding box. Click enter when you're happy with the results.

Next we want a tinted background. I'm going to go with the light pink.

Adding A Background Color
I select the background layer, Layer 1, and I fill it with the light pink by going Select> All, then Edit> Fill, and in the dialog box in Contents, I select Use: Color and in the Color Picker I enter FBE0EC.



The result is a 600 x 300 banner with a gentle background color and with the art placed on the left. We're getting there.

Apply A Thick Stroke To Create A Border
I decided to apply a thick stroke to the background layer to make the design more interesting. First make sure the background layer, Layer 1, is active, and create a copy by going Layer> New> Layer Via Copy. Next double-click next to the layer name. This will bring up the Blending Options in the Layers Style dialog box.



Select and then click on the word Stroke in the Styles options on the left side. I changed the settings to Size: 7px, Position: Inside, Blend Mode: Normal, Opacity: 100%, Fill Type: Color, and I clicked the color swatch and entered D04E8C in the color picker. Click OK.

The border is just to balance out the design, so by all means make changes and get creative with your own ideas.

Website Name & Section Titles
We're going to put the names of the major sections right on the banner. These will be the links. Since it will be just one single graphic we will be using image maps.



Create a new layer for your words. Use the type tool to create the section names and then use the move tool to position them exactly to where you want on the banner. Remember to pick a color for your text that is darker than your background color to avoid finding yourself screaming obscenities and suffering major hair loss! Do this by going Window> Character. In the Character palette you'll find a color square. Click on it to change colors.

You'll need an HTML editor like GoLive or Dreamweaver to automate this process. It's really very simple. You make little "maps" over each word and then enter the link destination. If you don't have an HTML editor you'll need to do a Google search on image maps to find a tutorial, or buy a book like Elizabeth Castro's HTML Quickstart Guide to help you out.

Plan B
You don't have an HTML editor, you don't want to search for a tutorial, and you don't want to buy Elizabeth Castro's book? That's ok. We'll go to Plan B - using regular text links right inside the web page itself. That means we have some empty space on the banner now, right below the website name. Use this space to add a descriptive phrase about what the user will find on your site.

The Separator
Create a new document. The width should be 600 pixels, and the height should be about 12 pixels. Fill this with your background color. Then, using the text tool and a dark color, type some periods, like this:........... and place them in the file, centering them. Change the size and the spacing until it looks perfect. Now save this as a GIF file.

Build A Simple Table
In your HTML editor of choice build a simple table that contains 5 rows and 1 column. If you're going to use text link navigation below the banner instead of image maps on the banner, create an extra row so you end up with 6 rows in your table. Now place your elements into the individual rows of the table and you're done.

The Final Result
It's time to have a look! Here is the final website page design.

How to Use Photoshop


INTRODUCTION

Photoshop's Variations and Free Alternatives

I have a different page that explains what Photoshop is, what the versions are and less expensive, or free, alternatives, here. I also talk about all the other software I use and photoshop plug-ins there.


I've been using Photoshop every day for years so its cost is negligible for what I get out of it. If I was starting from scratch and didn't have $560 for Photoshop CS or didn't get Photoshop elements for free with a scanner I'd first try iPhoto that comes for free with every Apple Mac computer, or Google's free Picasa 2 for windows, and learn those. iPhoto and maybe the others even read RAW files, so don't ignore them.

How to Learn Photoshop

A huge advantage of Photoshop is you have more ways to learn it, like this page here, than any other program. So many people know it it's easy to learn just about anywhere.

The best way to learn Photoshop is to take a class at your local community college to learn the basics of Lightening Underexposed Images and Correcting Color Casts and White Balance Problems. These basic adjustments are covered in every introductory Photoshop class and book so I'll just cover them quickly below. You must be fluent in these to get anywhere with Photoshop for optimizing images.

Photoshop also has built-in help as well as free tutorial usually included in the box. All you need to do is choose how you learn best and go that way. Personally I learn best from an in-person class or having an expert show me in person. When I have a question about how to find some obscure tool or how to make a command work I just choose help from the HELP menu.

Basic Operation and Tricks of the Trade

All these adjustments work with every kind of image. That's why skilled photographers feel sorry for people who toil away with RAW files just so they can correct exposure and white balance later. You can do it all to any JPG image in Photoshop without all the hassle.

The tricks below presume you have at least a basic navigational familiarity with Photoshop. You can get that from any book or community college class, or even the built-in help!

Photoshop has been around since the 1980s when it was only used by professionals. It therefore uses terms from traditional professional photography and the commercial printing press trades. Often these terms are exactly the opposite of what you'd expect! The most obviously labeled tools are sometimes the worst way to do things, so read up below.

People spend entire careers learning Photoshop. There is more to learn than any single human will be able to master. Each of us learns what's relevant to our own work.
