View Full Version : Adventures with the new HP G4050 - A newbie's review

A little background on me first:

I'm not experienced with scanners, the only scanners I've ever owned were the very cheap ones (such as the $50 canon lide25). I've been "scanning" my 4x5's by photographing them on a light table using my dslr and although I can get some pretty decent results that way, I wanted something that would give me better quality.

My goal is to have a scanner that will allow me to have web-res images as well as prints as large as 11x14". Anything larger than that and I'll send it out to my pro-lab to be drum scanned.


Now to the review:
Quick drive to my local staples, they had it in store. Paid $215 including tax, they have a 14 day return policy without restocking fee, so it was plenty of time to install it, do a few tests and return for refund.

I tried to install it on my Vista machine. Big no no. The HP website gives you some provisional drivers that as they state will provide basic functionality. Basic functionality doesn't include scanning transparencies. I called the HP's tech support and for my surprise, in less than 3 minutes I was speaking with a (indian) tech support guy. He confirmed the info, saying that they are working on a full functionality driver for Vista and will release it very soon, but he didn't tell me when. I understand that. I'm a software engineer and I should be working on the Vista compatibility issues of our software right now instead of writing this review...

So, Vista right now is a big no no.

Repeated the whole process on my XP machine. Normal process, in less than 10 minutes it was done.

The scanner is supplied with a few adapters: for 35mm strips (5 strips if I'm not mistaken), 35mm slides, medium format film (120?) and one specific for 4x5 (one sheet). It's plastic, seems to work fine.


I didn't like the user interface of the software. Looks old and it is confusing. I liked the buttons on top of the scanner. It's a nice shortcut to launch the software.

I got one of my trannies that I sent out to my lab (scitex eversmart pro), so I could compare with something I know is good quality. Then I scanned it at different resolutions and parameters. I'll show you below, but here are my conclusions:

1) The quality of the scitex is greater than of the g4050, but for the same size scan (8x10 @300dpi), I'd be plenty satisfied with the g4050.
2) For large scans (greater than 1200dpi), it is veeeeery slow.
3) You can define dpi and a "resize" parameter. In some situations, if you define the resize to larger than 400% (600% or 800% for example), it will completely mess up. The scan will be stretched horizontally and the RGB layers will be misaligned.
4) Even though HP software will warn you against it, I found it better to set resize to 100% and calculate the dpi in order to scan at a given output. For example, I found that scanning at 1200dpi will give me a good quality scan without taking the whole day to perform the scanning.
5) Given its slow speeds, I doubt I'd be using it to scan lots of 35mm film
6) It says it has digital ICE, I honestly couldn't tell if it was enabled or disabled... I had to spend some time in photoshop cleaning my scan (luckily my film is very clean).
7) The 6-color scan: either it is pure myth or I didn't know how to use it. I saw no improvement on quality and it took longer to scan. I wouldn't use it.
8) I tested mounting the film directly on the glass, with another sheet of glass sandwiching the film. Focus was identical (sharp) to mounting the film on the adapter.
9) Given 8 above, I felt tempted to wet mount the film, but since I wasn't planning on keeping the scanner, I didn't. When viewing at 100%, you can see some artifacts typical of dry scanning, I guess that it can be improved a lot when wet mounted.



My final opinion:
I will buy this scanner again at a later time for two reasons: 1) Because it is very cheap compared with others. 2) Quality is reasonable.


I'll post some images here for comparison.

Seems that the Dmax on the G4050 is the greatest difference. Even the D-SLR and lightbox combination seem to have better shadow details. This should not be that surprising in a low cost scanner.

If you did not have many night images, nor images with shadow detail areas, then it looks like the G4050 might be okay for internet usage. If you decide to wet scan with it, perhaps you can pull a bit more out of your transparencies. The lack of speed and what sounds like limited software would make it a non-starter for my uses.

Thanks for sharing your results. While obviously not scientific, I think the results are a good indication of performance.

Ciao!

I took a quick look at the 4050 when it first came out on the European market and decided not to test or review it because of its very limited capabilities.

Gordon, you hit the nail on the head stating that it is adequate for web scans.

I still have to test the V700, but I have the impression that it won't give me better results than the scitex.

Therefore, for small to medium prints (up to 11x14), I would live with the limited capabilities of the G4050 and spend the remaining $300 elsewhere. But that is with my needs in mind.

I still have to test the V700, but I have the impression that it won't give me better results than the scitex. . . . .

Assuming that the V700 is no worse than the 4990 that I've used for a couple years, and recognizing that evaluating the technical aspects of photographs on a computer monitor isn't the best way to do that, still the V700 should give you much better results than what I'm seeing here.

Continuing with my saga of pointless tests on cheap scanners, I bought a canoscan 8600F. My first surprise: the slit on the top of the scanner isn't wide enough to cover a full 4x5 tranny. Big show stopper.

Since I had it in my hands, I decided to go ahead and use my test tranny and see how it compares with the scitex, the dslr and the hg g4050.

Well, it at least had drivers for vista. If you have 35mm negatives, slides or 120 film, this scanner may be a very good option (paid $180 at best buy). It does a very good job at identifying individual frames and the speed is not so bad. Comparing the 8600F and the G4050 is like comparing a bicycle and a gsxr1000.

I scanned the tranny in two parts and merged it later in adobe elements. I didn't have photoshop in my laptop, so I had to struggle a bit with elements. The driver software is a bit cumbersome, especially when you're trying to scan something directly from the glass.

Anyways, here's a comparison again:

To the few still lurking this thread...

I finally gave up testing cheap scanners. Just bought an epson v700, it should arrive in the mail in the next days. I'll post my final comparisons when it arrives.

Thanks for the comparison. I have a Canon 8600F that I got for my 6x7 film scans and found out that it can not scan 4x5 but I have not yet decided if I will get something else. Normally the scanner has holders that keep the film above the glass, so I don't know how it behaves in terms of sharpness when set up to scan film that is placed directly on glass. Keep us posted with your impressions.

Regards, Stefan

The scan above of the 8600F is of a 4x5 transparency scanned at the glass. I laid another sheet of glass on top of the tranny to make it flat. The real bummer is that you need to do 2 scans and then stitch them together in photoshop if you want to scan 4x5s.
