EPSON flatbed scans are slightly stretched

[dave_roberts3]

Hi Everyone -

I am having a problem with distortion in many of my digital files. At

first I thought it was a photoshop problem, but it seems to be

popping up in all of my image editing programs.

 

The problem is horizontal distortion. It is particularly noticable

with human faces - they are wider than they should be. Many (but not

all) of my images look too wide until I scale the horizontal

dimension by about 97.5%. The 2.5% reduction in width makes

everything look natural again. This is happening with digital files

from my Canon EOS 10D and scans from my Epson 2450 and Minolta scan

elite 5400. This has also happened with files from a Canon EOS 1D.

 

I thought the problem might be in my monitor, but if that were the

case, then the prints should come out normal (I think) and they also

look too wide until I correct them by scaling as mentioned above.

 

My computer is an Athlon 1GHz with a Matrox G450 display card and 512

MB RAM. Monitor is a LaCie Electon Blue III. I use Colorvision

Optical software to calibrate the monitor and that seems to work

well...

 

Anyone run into anything like this before? Any suggestions?

 

Thanks for any assistance, Dave

Dave, I don't see how this can be anything but the horizontal sizing on your monitor. Create a blank 72ppi 6x6" image in photoshop, and measure the onscreen ruler with a physical ruler to verify that both dimensions are the same. If the H dimension is off, adjust the H on your monitor until it's correct.

I seem to have the same problem and would love to hear an answer. I have an epson 1640 and it happens when I scan ,but my g2 files seem ok.

Is your scanner software set to use output proportions other than 100% of the input? Or if not 100%, is the output demension not in proportion to input? For instance, if your original to be scanned is 4x5" and you set out put to be 11x14", the program will do that exactly even though the original is 4:5 (short demension is 80% of long) and the output is 11:14 (78.57%).

It can be at least three different things. One is your monitor. Number two is that maybe your negative drooped abit during the scan. Number three is that the linearity of the scanner is off. <BR><BR>Scan a reference glass negative; piece of graph paper; or a XY grid on Mylar; by using the flatbed in "reflective" mode; ie with no transparency unit. <BR><BR>WE have about 8 scanners; and have seen the distortion ususally to be negative droop with a large 120 and 4x5" negatives. Many times we are doing maping work; and this distortion REALLY is a PITA to deal with.
