Review: Epson Perfection v600 vs. v850 Photo Scanners

[ Disclosure: I purchased both these scanners for my own use. Updated March 17. 2024, with better information on dust removal technology.]

[ Update: Dec. 31, 2024. I just did a quick test comparing the scanning speed of a 2018 Intel Mac mini with an M4 Pro Mac mini using an Epson V600 scanner and SilverFast 9. While the processing was faster (i.e. descreen, color correction, dust removal) the scanning speed was the same.  Since the actual scan takes the most time, a faster computer delivered results only about 7% faster. ]

[ Update: Aug. 13, 2025. After a comment from a reader, I went back to retest automatic dirt removal. This involved rewriting the whole last section. ]

I am a long-time fan of the Epson Perfection V600 Photo scanner (V600). I’ve owned and used one for many years and it has provided highly reliable, high-quality scans. It has never failed in years of use.

Recently, though, I inherited hundreds, perhaps even thousands of historical slides that need to be digitized. After researching a scanner that would allow me to scan more slides faster but with precise image control at high-quality, I selected the Epson Perfection V850 Pro (V850).

Why? Because the V850 has all the resolution I need, saves into uncompressed formats like TIFF and PNG, has the image controls I need for high-quality scans from 35mm slides, and can scan up to 12 slides at the same time in a batch.

Both Epson scanners are very similar, but there are clear reasons to choose one over the other, depending upon your needs.

EXECUTIVE SUMMARY

In one paragraph, if all you need is to scan documents and photos, the V600 is the scanner of choice. It is fast, creates great images and is affordable. However if you need to scan transparencies as well as photos, are scanning dark, damaged or faint images, need somewhat  better dust and scratch control, or want faster performance scanning multiple slides, the V850 is the better choice. While both scanners scan at close to the same speed, the 850 using SilverFast software, can scan three slides at the same time.

Epson makes excellent scanners which live in the sweet spot of providing high-quality, high-resolution professional-grade scans without breaking the bank. Both systems, depending upon the scanning software you use, can scan up to 6400 dpi and save into PDF, PNG, TIFF, and JPEG. Epson scanners are popular (which means lots of third-party support), reliable and high quality.

NOTE: Both scanners offer interpolation for higher-resolutions. However, interpolation is like scaling a video image beyond 100%; all you are creating is fatter pixels, not better quality.

Scanners are one half of a two-part system: To make the most of your scanner, you also need high-quality scanning software. Both scanners come with Epson Scan 2, Epson’s scanning software. The latest version of Epson Scan 2 has problems running on M1 Macs. I’m disappointed in it. Epson seems to be taking the software in the wrong direction. Better scanning software is LaserSoft Imaging’s SilverFast SE Plus 9, which I cover in a separate review. (Read it here.)

Both scanners scan photos, 35mm slides, 35mm negatives and medium format film. Both have optical resolutions up to 6400 dpi (which you will never need). Both scanners work at 48 bit depth for color and 16 bit depth for black and white. Both scan images up to 8.5 x 11.7 inches  though both reserve about 1/4″ around all images that won’t get scanned. The V600 has an optical density of 3.4 Dmax, while the V850 has an optical density of 4.0 Dmax. (Dmax only applies when scanning slides, the higher the Dmax, the greater the image detail in shadow and highlight areas.)

Both can remove dust and scratches, though the V850 does a better job. As well, dust removal works best with slides, rather than prints. Both scanners are excellent at scanning documents as well as photos.

NOTE: Though, truthfully, if you are just scanning documents, one of Fujitsu’s SnapScan family of scanners is probably a better choice.

If all you need is to scan photos and occasional slides, the V600 is an excellent choice. If you need the highest quality slide and film scans, along with great photo scans, the V850 is a better choice. The V850 is also marginally faster than the V600.

GET STARTED

Both scanners include all the hardware you need to get started: scanner, power brick, plastic trays for holding transperencies, and Epson scanning software. However, the V850 (shown above) is also bundled with SilverFast. I’m not sure whether this software is included in the V600.

Connecting these is no different from any other computer hardware: plug it in and turn it on.

Installing the Epson Scan 2 software is also relatively straightforward and doesn’t take long. However, please read the manual. Don’t connect the scanner until after the software is installed.

SCANNING PHOTOS

From a spec point of view, the two scanners are essentially identical. Epson Scan 2 supports connecting and scanning from multiple scanners on the same computer, though only one scanner can be active at a time.

So, as a test, I used the Epson Scan 2 software to scan the same images on both scanners. Images can be scanned into TIFF, PNG, PDF or JPEG. I generally prefer TIFF, but PNG is uncompressed as well.

NOTE: I am not a fan of creating a high-quality image scan and mastering it as a  JPEG.

For this review, I scanned two 4×6 color prints and one color slide at a variety of resolutions and color bit depth on both scanners, then compared them.

This is the Epson Scan 2 interface, showing my two sample photos, which contain a wide range of gray scale and lots of color.

When I first wrote this article, I adjusted the Histogram of each image before scanning to get the best image possible. Epson Scan 2 provides Histogram, Curves and Color Balance adjustments. Then I realized that it would be better to use the default settings from the software for each scanner. Using the defaults gives a better idea of the results a new user would get.

NOTE: The following images were all scanned at 6K which created an image too big to post to the web. I then moved them into Photoshop and scaled them to 2K JPEGs so they could be posted. I did not make any adjustments to the image in Photoshop other than scaling. The scan settings were 600 dpi, 24-bit color, TIFF, with dust removal turned on for both scanners.

The V600 image is on top, the V850 on the bottom. Even with dust removal turned on, the V600 didn’t remove many speckles. However, from a scanning point of view, both images are very similar in quality.

(Click to see larger image – or drag to your desktop.)

Again the V600 image is on top and, again, notice the significant amount of dust the V600 did not remove using its default setting. (I explain this further in this article, it was caused by bad settings in the Epson software, not the scanner.)

Based on multiple tests, the two scanners create very similar scans at their default settings, though the V850 does a better job of dust removal. However, remember, image quality is a combination of both hardware and software; and the software was the same in both cases.

NOTE: As you can see in this second example, if the focus isn’t perfect in the print, it will look worse in a high-resolution scan. It is amazing to me how many really bad photos I’ve taken in my life.

I scanned both images as a batch and timed the total scan duration. Here are the timing and file size results for the V600:

• 48 bit color 1200 dpi: 2:21 (186 MB per print – TIFF):
• 24 bit color 1200 dpi: 2:21 (93 MB per print – TIFF)
• 24 bit color 600 dpi: 0:30 (23 MB per print – TIFF)

Here are the timing and file size results for the V850:

• 48 bit color 1200 dpi: 2:15 (186 MB per print – TIFF)
• 24 bit color 1200 dpi: 2:14 (93 MB per print – TIFF)
• 24 bit color 600 dpi: 0:30 (23 MB per print – TIFF)

When the two resolutions (1200 & 600 dpi) were loaded into Photoshop, they looked virtually identical when scaled to the same size. At actual size, both images looked blurry because the print didn’t have enough detail to support 1200 dpi scanning.

NOTE: The same resolution yielded the same file sizes on both scanners. This is what I expected. What I didn’t expect was that changing color bit depth did not change scan times, though it did change file size.

When working with printed photos, as opposed to transparencies, there is no reason to scan at more than 600 dpi or 24-bit color. Much though I would love to endlessly enlarge photos of family and friends, the resolution and color detail in the print itself just isn’t there.

NOTE: While there is no difference in scanning speed when adjusting color bit depth, there is a significant difference in scanning speed when adjusting resolution (dpi).

THE IMPORTANCE OF DMAX

The Epson v600 has a dMax of 3.4, while the 850 has a dMax of 4.0.

dMAX measures the highest density that can be captured by a scanner. What this means is that the 850 is able to pull more details out of shadows and dark images than the 600. Higher dMax captures more image details and reduces visual noise.

If you have a well-exposed, well-focused image, dMax won’t really matter. But for older, darker, faded images, it will.

SLIDE SCANNING

The V600 can scan up to 4 slides at a time. However, while the plastic slide holder holds the slides, it does not do so very securely. They can be easily bumped out of position. (The open strips to the left hold film negatives.)

If you have badly curved/bent slides, this holder won’t flatten them at all.

NOTE: Slides should be loaded into the scanner so they look correct (left / right and up / down) when you look down on them from above.

The slide holders for the V850 are more carefully thought out. The plastic guides feel a bit heavier (while you need to be careful as they can break, after two years of use, I haven’t broken any), and they hold the slides in place with little clips.

NOTE: If you have badly curved slides, these clips can help in flattening them.

The guides themselves slip into pins on the side of the scanner which assures that the position of the slides won’t change as you close the cover. I like both these features a lot.

(Click to see a larger version of each slide. Please do so to better see dust and sharpness.)

The top image is scanned from a 35mm slide by the V600 at 4800 dpi (scaled to 2040 x 1378) with dust removal turned ON. The bottom image was scanned by the V850 at 4800 dpi (scaled to 2040 x 1378) with Digital ICE dust removal turned on. The bottom image is MUCH better! Essentially slide dust removal is not properly enabled on the V600.

UPDATE: The Digital ICE dust removal technology makes a big difference, though it does slightly soften the image. However, while this first scanner test used the default ICE settings, the defaults on the v600 are incorrect.

Here are the file size and timing results for the V600 scanning the image at 4800 dpi, 24-bit color. (Note: I think the key reason these times are so close is that Epson Scan 2 software does not properly implement the infra-red scan required for dust removal.)

• Dust removal off: 1:06 (82 MB – TIFF)
• Dust removal on: 1:08 (82 MB – TIFF)

The V850 scanned the sample 35mm slide at 4800 DPI, 24-bit color:

• Digital ICE dust removal off: 1:01 (166 MB TIFF)
• Digital ICE dust removal on (Quality setting): 2:28 (166 MB TIFF)

I mentioned there is a big difference in dust removal between the two scanners. Let’s compare the two, again, this time using SilverFast 9.

The reason for using Silverfast, rather than Epson scanning software is that the default dust removal settings in the Epson software essentially disable it. Once the dust removal settings are adjusted to a higher level (12 in the case of SilverFast 9), dirt disappears.

Personally, I like how the 850 handles skin tones and color correction. The slide above is 71 years old and leans red. Note the speckles of dust throughout her white shirt. While the 600 removes dirt, if you look carefully you’ll still see remnants in the image. Those remnants are gone with the 850.

Also, the 600 tends to add a bit more sharpness than the 850. To match the images, I added one step of sharpness to the 850.

Both these images were scanned at 1600 dpi, and white balanced on the sleeve of her shirt. Manual gray-scale corrections were matched between scanners and scans. The softness in the image is less from the scanner and more due to poor consumer lenses that long ago.

NOTE: Dust removal for prints is MUCH less robust due to the infra-red technology used in both scanners. And, dust removal doesn’t work at all for B&W slides or negatives. It will work for a color slide that is scanned as black-and-white.

ADDITIONAL THOUGHTS

Both scanners connect via USB 2, which is more than fast enough to support the data coming from a scanner. If you have a Mac with only USB 4 ports, you’ll need a USB adapter, which costs about $20 for a set of two.

Epson Scan 2 really does not like running on M1 Macs. It continually lost connections with both scanners. This forced multiple restarts of both the scanners and software.

UPDATE: This review was written when M-series Macs were new. I haven’t tested Epson Scan 2 software since, as I use LaserSoft Imaging’s SilverFast SE Plus 9, exclusively.

A big advantage to using SilverFast for scanning slides on the 850 is that it will scan three slides at the same time on the 850 – all those in the same horizontal row. It also supports scanning up to 12 slides at once. This cuts scanning time almost two-thirds. The 600 only scans one slide at a time, with a maximum of four.

Though I’ve used Epson Scan for many years, the latest version is really difficult to use. Epson keeps trying to streamline the software. This effort is misdirected. While everyone likes automation to speed their work, if we wanted fast and cheap, we would not spend the money for an Epson scanner. As pros working with pro tools, we need easy access to image enhancement tools like the histogram, the ability to set and load presets and Curve and Histogram screens that don’t keep disappearing.

For example, after a preview scan, Epson Scan 2 sets the histogram levels such that both shadow and highlight detail are lost; this means that the Histogram needs manual re-setting for each slide before scanning. Also, tools like the Histogram are hidden multiple menus deep and there’s no way to save setting presets to speed scanning similar slides.

SUMMARY

Epson’s Scan 2 software is OK, but should be avoided if you are running on an M1 Mac. Instead, I highly recommend Lasersoft’s SilverFast 9 SE plus scanning software (the version just above the free version). It provides much better control over the scanner with higher-quality results.

If you are only scanning documents and printed photographs, the Epson Perfection V600 Photo scanner is an excellent choice. It creates scans that are the equal of the V850 for 1/4 the price and at roughly the same speed.

If you are scanning a few slides occasionally, the V600 is still a good choice, but only if you use LaserSoft’s SilverFast SE plus scanning software.

If you are scanning documents, photos, slides, negatives, or transparencies, especially where the source image is of poor quality, the scanning controls and quality of the Epson Perfection V850 Pro is unsurpassed, especially when you want to remove dust and other blemishes without degrading image quality. It is also slightly faster than the V600.

I’m very happy with the Epson Perfection V850 scanner because I have so many slides to scan. But the V600 is an excellent choice for those on a budget. And, in all cases, I’m using SilverFast 9 as my software.

NOTE: Here’s my review of SilverFast SE Plus 9 software, from LaserSoft Imaging.
