Epson 4490 + epson soft: understanding the color scan process ?

[Rom]

Dear all,

Would like to ask your advices on something that i do not understand.

I had a lot of troubles in finding a way to scan my 35mm negs with my epson 4490.

I only shoot B&W.

The best way that i found is to scan in color scan mode, 16 bit, 2400dpi and then, inside photoshop, i use channel mixer, levels, exposure (the same process that i do with my digital frames to translates it in B&W).

What i don't understand is on the same roll, some of my scans turns yellow and others turn red !!!? Why ? How a color scan from a b&w material can create color ?

Please find below 2 raw scans.

It seems that on the yellow ones, i can work on them more easily.

I know that the 4490 scanning machine is not the best but it's the best that i can afford for the moment and i am just doing scans for sharing not for printing.

Thanks in advance for your help.

All the best

Rom

Why dont you scan monochrome, 16bit greyscale?

Because it seems that color scan gives me more details than monochrom.

Why ? i cannot explain that.

Thanks

I have used this for a long time with my Epson 4490 scanner with its original software and it was giving me brilliant results.

Please let me know if you need any help translating these settings to your Epson scanner's settings (I am a bit rusty as I use Minolta scanner now but I should remember

Cheers.
