You should not be having this problem unless you have serious problems with development or odd light when you shoot! Scanning is part art and part science, though. It would be best if you experimented with your scanner and some well made test shots (like a Kodak 'Judy' portrait with true primary color objects, a grey card, Macbeth color checker chart all included) until you can create a profile to use as a base when scanning your problem film.

This has a permanent effect on the film image/record, and trying to balance in software after the fact can get you closer to the original scene, but can not add back the missing information. When you think about histogram curves for each color (channel) you'll see that using a particular filter will remove information from the other channels. Not sure the analogy of FL-D and car brakes applies to me given the information but that's okay ) I am also fairly competent in PS so will not shy from PSing my scans. Using filters for on-camera adjustment is something I do regularly. I am used to shooting E-6 so my adjustment has the original baseline which are in the original slides. So that is what I mean about 'manually adjusting'.

Having lived in the old parts of the world where film is still used, I've seen varying quality of prints depending on the technicians and labs and how to compensate for the C-41 mask. So certain adjustment in PS will be required. I realize the color is more the skill of the technicians when dealing with all C-41 film.

The prints I got from them have the full color saturation that I've struggle to duplicate from my scans due to that greenish cast.

The pro labs have the color profile for Ektar and the experience.

The Ektar color cast remains after scanning with the provide Epson V700 software. My main goal is to reduce the work load of color correction when scanning Ektar film, especially when shooting landscape. To OldUncleMe: Thanks for tips about using FL-D filter. Justin Berger edited this topic ages ago. Your mileage may vary but an FLD filter here is sort of like saying 'Oh my brakes are shot-but that's complicated to deal with, so lets get new tires and see if that helps.' What's 'manually correcting in PS'? Are you starting with gray balancing off the thing you want grey? or are youstarting with something else first? You've been having this problem for a while- what scanner are you using? Have you profiled it with an IT8 target? Are you trying to scan with a negative profile or are you scanning as an RGB positive and reversing? Have you given your negs to someone else to print and do they have problems with them? Unfortunately scanning is not the most intuitive or straight forward thing to do, so I understand the frustration.įirst of all, there is no such thing as a 'straight scan'. The incandescent will tend to other shifts, probably heading toward yellow/orange/red, but with the green/blue of an FLD and and unknown color temp light source, it's hard to say exackly. I've tried to manually correct with PS but would like to reduce the work load as much as possible.Īn FLD filter may work for you, but generally it will give a magenta cast for most people, assuming a daylight or even incandescent light source.

It does a great job of giving you accurate inversions without color casts. I make linear positive scans of my color negatives, and invert them using a Photoshop Plug-in named ColorPerfect. I think the color cast stems from using the wrong profiles in your scanning software or the wrong inversion method. I find this is the easiest way to remove colour casts. Scan the neg and then do separate shadow, mids and highlight correction to each colour channel. I suggest doing the correction in RAW or PS. I am trying to fix the Ektar color cast on the film rather than tweaking the settings on the scanner or in Photoshop. Has anyone tried to use the FL-D filter to reduce the green color cast in Ektar film? The FL-D is designed to remove the florescent light color cast in C-41 so I am thinking it may do the same for Ektar as well.
