System Interface and Included Software
The ES-10 comes in both SCSI or parallel-port versions, for both Macintosh or Windows environments. We tested the SCSI version for the Mac, although (based on a perusal of the manual) operation appears very similar on both platforms. On the Mac, the software interface is via either a standalone program (which saves files to PICT format), or a Photoshop acquire plug-in, giving you the full range of Photoshop's (or other compatible host program's) file format translation capabilities. The situation under Windows is similar, with a TWAIN driver substituting for the Photoshop plug-in. Also included in the package, for both Mac and Windows environments is Pictra Album, a presentation and image-sharing software package, InMedia's Slides & Sound Plus, a multimedia presentation package, and Adobe's PhotoDeluxe. (Cross-platform support is commendably excellent.)
On our Mac host system, we found system setup to be very simple and straightforward: A shipping lock screw needs to be removed from the bottom of the unit before scanning, the power and SCSI cables must be attached, and the software installed. All of this took well under five minutes, and we were happily scanning almost immediately. The ES-10 includes switches to both set the SCSI ID (with no arbitrary restrictions on allowed SCSI ID numbers, a sometimes overlooked necessity), and to enable or disable the internal SCSI termination. Another nice touch for existing SCSI chains is the provision of two connectors on the back panel, allowing the scanner to be inserted anywhere in the SCSI chain. (Some scanners provide only a single connector, forcing them to be the last device in the SCSI chain, a profound inconvenience in some situations.)
Operation and User Interface
Overview
Essentially all scanner operations are controlled from the main window of the ES-10's driver software, shown above. (The user interface is identical, whether within the dedicated software program, or the Photoshop plug-in.) Sub-windows provide for color and tone adjustment (more on this later), and the creation of an index scan if you are using the A-10 APS adapter. Focus mode is also initiated from this window, although the focusing operation itself is manual.
Focusing
Given the extraordinary resolution achieved by slide scanners, focusing is generally an important issue. (Although some units do employ "focus free" optics.) In the case of the ES-10, focusing is achieved by clicking the focus button on the main control screen of the driver program, positioning a "focus bar" in the preview image, and rotating a small thumbwheel on the left-hand side of the unit's top deck. Clicking the focus button puts the software into focus mode, and allows you to place a cursor on the preview scan indicating the portion of the image you want to use to focus the scanner optics. In focus mode, the scanning software continuously scans a single column of pixels across the width of the film, calculates the total pixel-to-pixel contrast difference (an excellent measure of "sharpness"), and displays the result on a thermometer-type display on the right-hand side of the screen. As you adjust the focus knob on the scanner, the thermometer bar display will move back and forth, indicating focus accuracy on a relative scale: The further the thermometer bar moves to the right, the sharper the focus is. If you go too far with the focus knob, the bar will begin to recede, leaving behind a small red mark showing the position of its furthest advance. In practice, a little back & forth will result in a sharply focused image with 15-20 seconds of effort. (We also found the focus adjustment fairly forgiving, the results of a fairly quick approximation being nearly as good as those resulting from a minute or two of obsessive twiddling.) The ability to choose your own focus point on the film is a decided plus, as choosing a high-detail area results in both faster and better focus results than using one with less detail.
Exposure and Color Adjustment
The ES-10 provides controls for both overall "exposure bias," as well as tone-curve-based adjustments for highlights, shadows, and gamma (think of this last as a brightness control for the midtones), either on an overall basis, or for each color channel (red, green, and blue) independently. The controls predictably do what you would expect them to, with the exposure bias slider providing a fairly strong adjustment to overall scene brightness, and the curve controls offering more subtle tonal and color correction.
The tone curve adjustment panel is accessed by clicking the "Color" button in the lower right-hand corner of the main control screen. This brings up the "Color" window, shown here at right. Here, the Red, Green, and Blue buttons select which of the three channels will be adjusted by the controls, while the RGB button lets you move all three channels together. Generally, you'll use the RGB control first to set the overall tonal balance of the image, and then make any necessary color corrections using the individual color controls. The "Monotone" button converts color images to gray-scale ones. (We didn't experiment with it, but the manual mentions that you can create "sepia" and other toning effects by converting an image to monotone, and then adjusting the RGB controls to create the desired effect.)
As you make adjustments in the various color settings, the preview image is updated to reflect the changes you've made. This does a fairly decent job of giving you feedback as you work. For best results though, you need to click the "Preview" button again to generate a fresh preview based on the new settings, particularly if major adjustments were made. If you want to get back to where you started, the "Reset" button will set all controls back to their neutral positions.
We found the color adjustment controls of the ES-10 to be powerful enough to deal with typical color-correction needs, but would liked to have seen a few additional features to ease the workflow a bit. Highest on our wish-list would be some way to save the control settings to a file for later recall: When switching between different types of color negative film, some color adjustment is almost always necessary, and it would be nice to be able to recall prior settings. (The scanner software retains the previously selected control settings between sessions, but if you switch to slide film, you have to start over again when you go back to negatives.) We found we could work around this by using the arrow buttons to adjust the sliders, recording the number of mouse-clicks we adjusted each up or down, but this was more work than it needed to be. If most of your work involves a single type of film though, this won't be much of an issue.
Perhaps a more fundamental issue in the software's user interface is that we couldn't get numeric feedback on the effect of our adjustments without hopping back and forth between the Color panel and the main preview screen. The preview screen will display the RGB values of the pixel under your cursor, whenever you move the cursor over the preview image. This display doesn't update in a "live" fashion as you make adjustments on the Color screen though, making it a trial and error process to adjust highlight and shadow values accurately, or to neutralize color casts. (Our personal preference for color adjustment controls are histogram displays of the sort provided in Photoshop's Adjust/Levels tool.) Of course, having just mentioned Photoshop parenthetically, many of our complaints about color adjustment can be overcome by using the ES-10 plug-in within Photoshop, and then making your final adjustments in Photoshop itself, rather than in the scanner software. (Photoshop also allows you to save color-correction adjustments to disk for later recall, eliminating that concern as well.)
Resolution/Scan Size
The ES-10 control software operates in either "pixel" or "resolution" modes. The screen shot included earlier shows the control layout for "pixel" mode, in which you choose from a set of fixed pixel dimensions for your final scan. This was the mode we ran the scanner in almost exclusively, as we wanted to be know the exact pixel dimensions of the images we were scanning, for future comparisons. Most users will probably find the "resolution" mode more convenient though.
n pixel mode (screenshot clip shown at left), you specify the desired size and resolution of the final image, rather than the pixel dimensions. This corresponds to the way most users will probably work: For instance, once you've established that 240 dpi is the file resolution that works best with your 720 dpi printer, you can simply select 240 dpi for the output resolution, and then type in either the width or height of your desired image output size. The scanning software will automatically compute the pixel dimensions required, and set up the scanner accordingly. While we didn't play with this mode extensively (give that none of our work was specifically intended for print output), we found resolution mode very intuitive and useful even in our limited experimentation. Were we to use the scanner regularly for printed output, we suspect this would become our mode of choice.
Previewing, cropping, and rotating
The ES-10 provides a good-sized preview image to use as a reference for color adjustments, but does not allow you to zoom in or out on the image for fine adjustments. We also would liked to have seen a control in the interface for cropping images prior to the scan itself. This is really minor point, as it is easy enough to crop once the image is in the image-editing application (if you're using the plug-in or TWAIN interface), but it would still be nice to eliminate the separate step.
A nice touch in the ES-10's user interface is the presence of the "Rotate" button. Each click of this button rotates the preview image another 90 degrees clockwise. This makes it easy to handle accidentally-inverted images, and prevents the natural inclination to twist your head while viewing "portrait" images laid on their side. The orientation of the preview image is preserved in the final image file.
Scanning Speed
(NOTE: The times reported here are for the SCSI-interfaced Mac-based product. Scan times for an ES-10 connected to a Windows PC via a SCSI connection should be quite similar. The parallel-port version will undoubtedly operate slower, especially at higher resolutions where the slower transfer rate of the parallel port becomes an issue.)
One of the things we liked about the ES-10 was its speedy preview: The scanning head intelligently scans in whichever direction is appropriate, depending on where it was left after the previous operation. Previews of 35mm film took about 12 seconds once we clicked the "Preview" button. Full-resolution (2400x1600) scans took 80 seconds, while half-resolution (1200x800) ones took about 66 seconds. Based on our current (6/98) knowledge, these scan times appear to be average to slightly faster than average for personal film scanners.
Supported Film Types
One of the things we've learned in playing with film scanners is just how strange color negative film is! Proper color-correction of color negatives during scanning turns out to be quite an art: Not only do you need to compensate for (substantial) variations between film types and brands, but the orange "masking" can also vary in density with the underlying image content. Overall, it's far from straightforward to sort out the necessary color transforms when scanning color negatives.
The ES-10 (and most other scanners we've seen) deal with this in part by having custom color profiles for different film types. In the case of the ES-10, profiles are provided for the following manufacturers and film types.

Test Results
As always with Imaging Resource reviews, we encourage you to let your own eyes be the final judge: Look at the sample images, download them, print them out on your own printer, and decide for yourself how well the ES-10 would meet your requirements!
Overall, we were quite pleased with the output from the ES-10, especially when we compared it to the output of high-end digital point & shoot cameras. There's no question (at least for now) that the combination of film + scanner blows away even the best digital point & shoot cameras. Direct comparison with our digital camera tests is somewhat confounded by the fact that we simply have different test targets for the two sets of devices. Even allowing for this discrepancy though, it's not hard to see the superior image quality this scanner offers over the best of the digicams. (Before we're accused of ignoring the many advantages of digicams though, we hasten to point out that they do have multiple benefits of their own, including immediate feedback, a low "hassle factor," and faster turnaround.)
We found the ES-10 capable of producing beautiful scans, albeit after a little preparatory twiddling of the scan controls. If you commonly use a single type of film for most of your shooting, you should be able to arrive at a set of default settings that reduce frame-to-frame tweaking to a minimum. In exchange for your setup efforts, scans from the ES-10 carry tremendous amounts of detail, and excellent color.
The default settings for slide scans tend to produce rather dark images. We found that setting the "Exposure Bias," "Shadow," and "Gamma" adjustments upward slightly produced good scans with excellent tonal gradation. We don't have a good translation between the grayscale on our Q60 test target and numeric density values, but believe that the maximum-density performance of the ES-10 will be adequate for the vast majority of users. (On the Ektachrome Q60 target, the ES-10 resolved density steps down to about step 20.) Once the basic exposure adjustments are made, the resulting images show excellent tonal gradation, color saturation, and color accuracy.
As mentioned above, color negative film is flat-out weird! We tried a variety of color films in the scanner, but standardized on Kodak Gold 100 for our "official" test images. (We could spend the rest of our lives trying all the variations and permutations of film manufacturers, emulsion types, and film speeds.) The provided set of preconfigured color profiles for color negative films from Agfa, Fuji, Kodak, Konica, and "Others" provide a broad range from which to select basic color profiles: Chances are, even if you aren't using one of these specific film types, you'll be able to get decent results by experimenting a bit to find the best match for your film.
In the case of our primary tests, using Kodak Gold 100 film, we chose the "Kodak Gold" color negative setting on the scanner software, and achieved good results overall. The Davebox target sample shows an overall yellowish cast that was typical of this combination (and which could doubtless have been removed through proper adjustment of the scanner software's Color controls). In practice, and particularly since we weren't doing large numbers of scans with the unit, we found that a simple "Auto Levels" operation removed the color cast in one step. Colors were very bright, clean, and highly saturated.
We found the ES-10's resolution to be very good, particularly in contrast to images from the digital cameras we've tested to date. While the ES-10's maximum resolution is "only" 1770 dpi, and Olympus sells it as a "3.84 Megapixel" scanner, the actual results were quite impressive. Look at the fine detail in the "House" clip, where the pine needles are seen against the sky. Look too at the resolution target clips. We found it interesting that the resolution of the ES-10 was quite different in the vertical and horizontal axes. It appears that the scanner is doing some interpolation along the vertical axis, and less or none in the horizontal direction. Visual resolution on the WG-18 target scan was roughly 1000 line pairs/picture height in the vertical direction, and 1300 horizontally.
See for Yourself!
Take a look at the test images from the ES-10, download them, print them out, see if the scanner meets your needs!
Conclusion
The ES-10 appears to be an excellent scanner for personal use: With minor tweaking, it produces images with resolution and color quality significantly exceeding even moderately-expensive (up to ~$1,500) digital cameras. While the combination of film-plus-scanner obviously lacks some of the convenience of the fully digital approach, a personal film scanner like the ES-10 could be the best choice for those reluctant to give up the flexibility of film.
