Even a close-up, zoomed-in examination will not give you a clue as to the real color of the model’s eyes. This is because I’ve used the Color Replacer option in Photoshop to replace the color. In fact, Marianne (the model) has killer blue eyes. She could just as easily have had brown eyes, though, and you’d never know for sure if that was the color I replaced.

The reason that it’s so hard to tell that the color has been replaced is that all of the surrounding shades of blue in the eyes have been replaced with corresponding shades of green in the middle third and with brown in the bottom third of the image.

The best part of the process, in my opinion, is the ease with which it’s executed. The hardest part is making the selection. You’ll need to select the areas you want to change, otherwise any areas in the image that contain the same color(s) will be changed, as well.

Because of the nature of the tool, though, you don’t have to be too exact in your selection unless the area you’re selecting is surrounded by areas with similar colors. If, for example, Marianne was wearing blue eye makeup, it would have been prudent to exclude that area as I selected the eyes. I simply used a circular marquee and removed some of the selected areas using the Lasso tool.

To show you the process and how it works, I’ll use another image with this scenario: Say you’ve just finished working on an image for a client. The photo shoot has been done, the image(s) selected and retouched, the layout almost done, etc. when the client decides that they want to go with another color of lip gloss for the campaign. Panic sets in, right? Wrong!

Load the image into Photoshop, select the model’s lips, and choose Image, Adjust, Replace Color.

To get started, I’ll zoom-in on the area I want to work on.
I’ll then, select the area using the Lasso tool. Depending on the image you’re using and the area you need to select, you may want to use a different method and/or tool.
You can see that I’ve already started the process.
I’ve zoomed-in, made the selection and run the Replace Color option. As well, I’ve chosen the initial shade that I want replaced and I’ve chosen the color I want it replaced with.

To do so, I selected the middle Dropper tool (the one with the small plus sign), shown with a red pen mark around it , and clicked on the color I want to replace. Because of the nature of the replacement, I chose one of the brightest reds in the models lips.

After choosing the primary color I want replaced, I used the sliders to set the color that it should be replaced with. In this case I simply set the Hue to -31 and left the Saturation and Lightness alone.

To complete the change I simply clicked the other red pixels that were unchanged. Doing so replaced them with corresponding shades of the new color I had chosen.

I told you the process was easy!

The Adobe Gamma control panel should be located in the Program files/Common
files/Adobe/Calibration folder which can be easily accessed on a PC by going to My
Computer and selecting Control Panels.

Adobe Gamma will now work with most PC
computers, providing the video card will allow Adobe Gamma to interact with the
monitor tube. Do not use the older Gamma control panel which shipped with
Photoshop 4.0 or earlier. This older control panel must be discarded.
When you launch Adobe Gamma, you have a choice of using it in either Control
Panel or Step By Step (Assistant) mode. Select the Assistant radio button and click
Next. If you already have a monitor profile, such as a canned profile supplied by the
manufacturer, click the Load… button, locate this profile and use that as your starting
point. Any existing monitor profiles should be found in the ICM Color Profiles folder.
If not, any will do as a starting point here. You will be asked to set the monitor
contrast to maximum. The single gamma display box will only allow you to adjust
the relative brightness. But since you will want to neutralize the color as well, uncheck
the View Single Gamma Only box and adjust the three color boxes as outlined in the
Mac OS X calibration routine.
The Windows default gamma is 2.2 and this is the best monitor gamma setting for
most Windows graphics cards. The white point should be 6500 K, if unsure, try
clicking on the Measure… button and following the on-screen directions. The next
screen asks if you want to work with a different white point other than that entered in
the previous screen. Unless you have a particular need to alter the white point, leave
this set to Same as Hardware.

If you are using a thirdparty method of profiling the monitor on the Macintosh, other than a system
utility, you may be required to manually load this profile next to where it says Display Profile in the ColorSync Control Panel (OS 9), or in the ColorSync System preference (Mac OS X). On a PC, you will probably need to carefully consult the instructions which came with the calibration device. These should guide you through the intricacies of how to configure the Windows system setups.

Open your photo in Photoshop and get to work by resizing it, copying it to a new document, or whatever you want to do with it

1. Colourise: Create a new layer (layer > new > layer) then get out the Gradient Tool. Using the gradient tool, add a very bright radial gradient onto your new layer, Try a few different layer modes and see which one looks best to You. You might also want to try a few different Solid Color fill layers, then mess with the settings for those, but this will be fine for now.
2. Shapes / Details: For this part of the tutorial you might want to hide the layer we previously made (the gradient layer). Start by getting out the Custom Shape Tool and finding the heart shape (or any other shape you think would look cool). Create a new layer and make a few white hearts on your canvas.As you can see in the above image, I also rotated a few of my heart shapes to make it look a little more interesting! Finish off with the hearts by adding a larger, pink-filled one in the background (behind your white shapes).
3. Halftone Effect: Now we want to add something really interesting on top of our hearts/shapes. Start by opening the Channels tab (window > channels) and creating a new channel (create a new channel by clicking the icon at the bottom of the palette). You might need/want to make a new layer before doing this channel business. Now to make an interesting effect out of these boring dobs — go to Filter > Pixelate > Color Halftone and use an appropriate setting (you’ll have to press OK and check if it’s good enough). Using 32 as your Max. Radius should be good enough. Now, holding ctrl down on your keyboard, click on the thumbnail for your new channel, this will select the pixels. Go back to your layers palette and select a new/blank layer. Fill your newly-made selection in the fresh layer with the very bright & colorful gradient that comes with Photoshop.
4. Image Adjustments:  would probably have made more sense to do the image adjustments at the start of the tutorial, but now we know what our outcome is mostly going to look like, we can make some photo adjustments to our stock. The main thing I did was add a levels adjustment layer below our screen gradient layer (note: layer > new adjustment layer > levels).

Ukuran diatas adalah ukuran umum yang dipakai distudio cetak foto, sekarang berkaitan resolusi image (foto) yang akan dicetak, bisa dilihat di Photoshop: klik [image]>[Image Size] lihat dibagian resolution:

Contoh Image Size diatas adalah untuk ukuran foto 4R, dengan besar Resolusi 300 dpi. Jadi format foto yang akan dicetak ke studio cetak foto adalah ukuran 4R. Sebaiknya gunakan format JPEG dengan mode RGB color. Besar Resolusi 300 dpi adalah yang paling ideal untuk setiap ukuran cetak, tetapi tidak harus sebesar itu, 150 dpi pun menghasilkan hasil cetak yang bagus.

Saat ini sudah ada jasa cetak foto via internet dengan mengupload file foto keserver tertentu. Tetapi berkaitan ukuran data vs kecepatan koneksi internet, maka perlu penyesuaian ukuran data. Berikut adalah tabel yang menunjukkan relasi antara ukuran foto dengan ukuran resolusi:

Before you scan an image, make sure that the software necessary for your scanner has been installed. To ensure a high-quality scan, predetermine the scanning resolution and dynamic range your image requires. These preparatory steps can also prevent unwanted color casts from being introduced by your scanner.
Scanner drivers are provided and supported by the manufacturers of the scanners, not Adobe Systems Incorporated. If you have problems with scanning, make sure that you are using the latest version of the appropriate scanner driver.
You can determine the resolution for your scan using the original and final image dimensions and the resolution of your output device. Scan resolution translates into image resolution when you open the scanned image in Photoshop.
To estimate scan resolution:
Do one of the following:
For laser printers and imagesetters, multiply the printer’s screen frequency by 2. To determine your printer’s screen frequency, check your printer documentation or consult your service provider.
For inkjet printers, check your printer documentation for the optimal resolution. Many dye sublimation printers and devices that print directly onto photographic paper have an optimal resolution of 300 to 400 dpi.
Determine the ratio of the final image dimensions to the original image dimensions. For example, the ratio of a 6-by-9-inch final image to a 2-by-3-inch original image is 3.
Multiply the result of step 1 by the result of step 2.
For example, suppose you are printing to an imagesetter with a screen frequency of 85 lpi and the ratio of the final image to the original is 3. First multiply 85 (the screen frequency) by 2 to get 170. Then multiply 170 by 3 to get a scan resolution of 510 ppi. If you are printing to an inkjet printer with an optimal resolution of 300 dpi, multiply 300 by 3 to get a scan resolution of 900.
Note: Different color separation procedures might require different ratios of image resolution to screen frequency. It’s a good idea to check with your service provider or print shop before you scan the image
If your scanned image contains an unwanted color cast, you can perform a simple test to determine whether the cast was introduced by your scanner. If it was, you can use the same test file to create a color-cast correction for all images scanned with the scanner.
To identify and correct a color cast introduced by a scanner:
Make sure that your monitor has been calibrated.
Open a new Photoshop file, and use the Linear Gradient tool FPRIVATE “TYPE=PICT;ALT=Linear Gradient tool ” to create a blend from pure black to pure white.
Choose Image > Adjustments > Posterize, and posterize the blend using 11 levels.
Print the 11-step gray wedge on a black-and-white printer, and then scan it into Photoshop.
Note: You can also perform this test using an 18-percent neutral gray card or an 11-step gray wedge from a photography store.
Open the Info palette, and read the RGB values on-screen for each of the gray levels. Uneven R, G, and B values indicate a color cast.
Use Levels or Curves to correct the color cast, and then save the dialog box settings.
Open the scanned image you want to correct, reopen the dialog box you used to correct the cast in step 6, and load the saved settings.
