can i calibrate a plustek scanner without original calibration sheet

Using a curves layer & clipping warnings, clip black and white points in each of RGB. In Photoshop you want to use ProphotoRGB colourspace, sample the base density, use that to fill a new layer set to divide - then flatten, & invert. Some of the pre-set modes in Flexcolor are sort of OK, but for best results you should scan as a transparency with no clipping & some neg rebate, possibly using a curve to open up the areas of density that will become highlights. You can get very accurate colour from a flextight, and you will discover that the Epson's sense of 'colour' is rather poor by comparison. To obtain the same with the V750 you have to scan at 3200 and then you can reduce the image size. Anyway the Flextight is Pro machine: the 2000 dpi scan is good. If you have the problem with roll film you can also solve it with a dedicated roll film scanner, like the Plustek 8000 series, or the Plustek 120 that also makes MF.Ī Flextight will shine when you have extreme densities you want to recover, but for 4x5 film you won't obtain a substantially sharper scan than with a V750, because the flextight has a 8000 pix sensor that when scanning 4' wide it only takes 2000 samples per inch. If 'sharpness does seem vary from neg to neg' this can be because curled negatives, you first can try to address that by trying wet mounting or by simply purchasing the V850 film holders that have an ANR glass to ensure film flatness and also to adjust film height. Also I agree that the V750 makes a surprisingly good color job, this is extraordinary given the price. You always can make a device work mostly like another one by making a 3D LUT that converts from one to the other in PS, this can be made with 3D LUT Creator software for example.īeyond that Flextight systems are top notch, I've never been aware that somebody was complaining about the color interpretation of those devices, scans I've seen from flextights are simply amazing. Anyway the color interpretation may differ because the dyes filtering light on the pixels on the linear sensor, and because the particular illumination the scanner uses. Scanners are (IT8) calibrated systems tending to deliver the same colours. I'm considering buying a Flextight but I'm just wondering what the colour is like from the scanner's software? Is it difficult to get good colour balance?

The colour is 90% there straight out of the Epson software, however the sharpness does seem vary from neg to neg. I've been using my Epson V750 for colour neg scanning and it's surprisingly good.
