For information on how to scan different types of originals simultaneously, see Batch Scanning

Choosing the Scan Resolution

Resolution refers to how m any dots per inc h (dpi) or dots per centimete r (dpcm) you want your scanned image to contain. These sections tell you how to selec t th e best resolut ion for your image:

◗ Factors to C onsider in Selecting Res olution ◗ Changing the Resolut ion

Factors to Consider in Se lec ting Resolution

The best res olution for a sc anned image depends on the type of image you’re scanning and your final outpu t d ev ic e. T he higher a resolution you select, the larger the res ult ing image file . Fo r ex ample, an 8.5 × 11-inch original sc anned at 300 dpi can produc e a 24MB file. T he same origin al scanned at 72 dpi creates only a 1.3MB fil e. If y our scanned im age is intended only for on-sc reen viewing , yo u c an scan at 72 dpi t o reduce your file size.

Large files ta k e longer to proc es s and print, so co ns ider the prac tical limitations of your computer system and hard disk drive when selecting a resolution. To keep your file size manageable, select the lowest possible resolutio n t hat gives acceptable qualit y .

As a rule of thumb for any im age except line art, use a scanning resolutio n t hat is approxim ately one third of your output resolution. F or example , u s e a s c anning resolution up to 100 dpi wi th a 300 dpi laser printer, an d up to 200 dpi w ith a 600 dpi laser printer.

Basic Scanning Page 20

For ink jet printers, such as an EPSON St y lus s eries printer se t to 1440 dpi printin g m ode, use a sca nning resolut ion of approx im at ely 300 dpi (select a pproximately 240 dpi for 720 dpi pri nt ing mode).

For a list of re c om m ended resolutions for sp ec if ic im age types, see

Setting Up and Using Your Scanner

Changing the Resolution

To chang e t he resolution to a sp ec if ic s et t ing, move the re s olution slider to the left to decrease resolution or right to increas e res olution. Yo u c an also ente r a res olution in the fie ld and switch bet w een dpi (dots per inch) and dpcm (dots per centi m et er) measure m ent units.

click to switch between dpi and dpcm

If you select an appropriate resolution for your image, and then enlarge it by scaling it or selecting a larger output size, SilverFast Lite automatically increase s th e res olution proportionally so yo u don’t need to adjust the resolutio n t o retain your image quality . For example, if yo u’re scannin g a 2 × 2-inch photograph at 300 dpi and then enlarge the output s iz e t o 4 × 4-inch (a 200% enla rgement), Silv erFast Lite aut om atically scans the image at 6 00 dpi, even though the reso lut ion slider is sti ll se t to 300 dpi.

If you adjus t th e res olution to a hi gh s etting, keep th e f ollowing in min d:

◗ You’re sc anning at a reso lut ion that gives great results for photos, and ◗ You’re creating a very large file size us ing your curre nt s et ti ngs

Basic Scanning Page 21

In some instances, you may you’ll be enlarging a sm all s c anned origin al in your applic at ion program and want to retain a high image quality. In that case, you may want to select a resolution between 1200 and 2400 dpi so you can enlarge it later with good results.

In other instances, you may be your image. For example, if you’re enlarging an image’s size in SilverFast Lite so the s c anned file loads int o your applic at ion already enlarged, you may not need to select a s h igh a resolutio n fo r a s uc c essful scan. Your settings are c reating a file that may be slo w to p roc ess and burd ensome to your system resources.

If you move t he resolution s lider to a very high resolution fo r it s siz e, you see a mess age warning y ou that the soft w are will be “inte rpolating” the resolution you selected. This means that the software must add pixels to your imag e t o ac hieve the resolution you ch os e, but may not increase your image quality. If you see this warning message, you may want to lower the re s olution settin g.

Creating Frames

When you fir s t p res c an your docu m ent, SilverFa s t L ite places a default frame (the dotted line) around the border of the entire scan area. I f the Original setting is set to Re fl ective, the sca n area is the entire documen t table (8.5 × 11.7 inches). If you select Transparency or Neg.

Transparency, the entire scan area is 4 × 5. If you selected Spectra Polaroid, the maximum scan area is 4 × 3.5 inches. If you selected 600 Polaroid, the maxi mum scan are a is 3 .5 × 3.5 inches. (See Choosing the

Resizing and Moving Frames

You can resize or move the default frame or the active frame, if you’ve created multiple frames.

To resize a f ram e, move the m ous e pointer ov er t he frame bord er; t he pointer cha nges to a two- or four-headed arrow. Clic k and drag the frame border to the size you want.

To move a frame, move the mouse pointer anywhere within the frame; the pointer ch anges to a han d. C lic k and drag the fra m e t o t he position you want.

You can’t c reate multipl e fr am es if the active frame is zoomed. Click the

Unzoom button before c reating multipl e fr am es. If you create multiple frames and then zoom, the inactive frames disappear from the zoomed prescan image.

Basic Scanning Page 25

Creating Multiple Fra me s

You can cre at e m ult iple frames on one image or frame several images at once. Then you can either scan the frames one at a time or batch scan them all at once. You can even select dif fe rent settings f or each frame, allowing y ou to try variou s set t ings for the same image or scan multiple images of different types, such as color photographs, grayscale images, and line ar t.

To create multiple frames, move the mouse pointer inside the prescan area anywhere outsid e t he d efau lt fr ame b ord er. ( In Wi ndo ws, th e poi nt er becomes a crosshair.) Click and drag the mouse to create the new frame.

The new frame border is a dotted line, indicating that it is the active frame. Any other fra m e borders bec om e solid lines .

If you’re creating multiple frames for batch scanning, select the settin gs fo r one frame before creating another (s ee Batch Scanning for details).

You can copy settings from the active frame to another frame by holding d ow n t he Alt key (Windows) or the option key (Macintos h) and clicking th e t arget frame.

To view the frame numbers of each fram e (on the Macintos h only), press the control key.

To duplicate the active frame, hold down the Alt key (Windows) or the option key (Macinto s h) and click in the upper left corner of where you want the new frame pos it ioned.

The active frame is the last frame you create, unless you change it to another frame, as described in Moving Between Frames

Moving Between Frames

Once you ’v e c reated multiple frames (as described in Cr eat ing Multiple

Frames), you can modify each frame as necessary for your scan. To

modify a frame—such as resize it, delete it, or select settings for it—it must be th e ac t iv e f rame (indica te d by t he border with th e dotted line).

To select a different frame as the active frame, move the mouse pointer over the solid border of th e inactive frame; the pointer becomes a w hite arrow. Click the border; it becomes a dotted line to indicate it is the active frame.

Sizing the Image

The amount of computer memory or disk space required to store an image depends on several factors. T he following sec t ions describe these factors an d ex plain how to res iz e y our scanned im age:

◗ Factors A ffecting Reso urce Require m ents ◗ Changing the Size of th e Sc anned Ima ge

Basic Scanning Page 28

Factors Affecting Resource Requirements

These fac t ors af f ec t th e resources required to store a scanned im age: Type of Original The size of a scan ned image depe nds on t he type

of original. C olor images re quire up to 24 bit s of

each

computer memory or disk space for dot in the image. Howev er, grayscale im ages require on ly 8 bit s per pixel, and blac k and white line art requires only 1 bit per pixel.

Scanning an original as a color image requires three times as m uch storage as scanning it as a grayscale image, and up to 24 times the s t orage requirement of a black and white line ar t image.

Size Scanning a 2 × 2-inch origin al creates a smaller

file than an 8 × 10-inch original.

Scaling Scaling (enlarging or reducing) an image changes

the file size accordingly. For example, scanning an image scaled to 150% of it s original size req uires 50% more s t orage than scaling it at 100% .

Scaling ch anges the actual output size; zooming changes only the view on your screen.

Changing the Size of the Scanned Image

When you scan an image us ing the defa ult s et ti ngs, the outpu t image is scanned at the same size and proportion as the original image. However, SilverFa s t Li te let s yo u c hange the size of the output im age, either by changing the scale of the original or b y se tting the size of the final image .

The relati ons hip betwee n t he size of the fram ed original, t he s c ale, and the output size is:

Frame siz e × Sc ale = Output si z e

For example, a 2 × 3-inch frame with a scale of 200% makes your scanned out put size 4 × 6 inches. It also increases your scan resolution by 200% to ret ain image quality; see Ch anging the Re s olution

Maintaini ng Size Ra tio (P roportional Scaling)

If you were to sc ale the width on an image differently from the height, the scanned im age would look s t ret c hed or distorted. Proporti onal scaling keeps the proportions of an image (wid th and height) the sa m e w hen enlargin g or s hrinking the im age.

When you use proportional s ca ling and you chang e th e wi dt h or height of an image, Silv erFast Lite aut om atically adjusts the other dimension to maintain th e s am e width-to-height ratio.

Adjusting Tone Curves

When an image needs adjustment, it’s usually because it is too dark or too light. However, sometimes only parts of an image need adjustment. In such cases, you can use a tone curve to adjust only those tones that are too dark or to o light. You can adjust the ton es in t he middle range (midtone s ) as w ell as the highli ghts and shadows by chan ging the shape of the tone c urv e.

For example, you may hav e a group pho to w here everyon e is w ell-lit except one person in th e f oreground who was too clo se to th e f las h and looks washed out. Since the other subjects in the photo look fine (they are in the midtone ranges), you can adjust the washed-out area (the highlight range) by decreasing th e highlight val ue of the image. Or s uppose you have a phot o w here some objects are too d ark and others ar e t oo light (such as an outdoor phot o on a bright, sunny day). D ark ening the highligh ts and lightening the shado w s ca n balance the ton es .

There are several to ols you can use to adjust the tone curves. It may take some practice to find the best ways of using these tools for optimum results. S ee t hese section s fo r details:
