Question re M240 colours

Help please. Recently got my M240 and have a question or two re colours. With the M8 and M9 I used PS CS3 and 5 for post processing and don't recall any colour issues. Using the same methods with the M240 (Haven't strayed into Lightroom yet...), I've noticed that yellows (those nice autumn golden yellows) are rendered "mushy" and the sensor seems to have even more difficulty with that colour if it's surrounded by greens (conversely, the greens seem to get 'lost' if surrounded by the mushy yellows). Also, the sensor seems to like to make some dark tones blue or purple (e.g. power lines (should have been black, came out blue in parts) or tree branches - the latter example of purple edging when underexposed (deliberately), and some shades of foliage turned form greens into petrol blues). Early days yet with the camera and it's possibly me being a numpty, but any ideas?

Lots of lengthy threads on this topic already; search box will bring them up.

 

Short story, as jip alludes, try a custom profile, e.g., using something like ColorChecker Passport, and/or simple white balance card; and, yes, do make sure you have the latest FW loaded.

 

As far as blacks becoming purples in some instances, this is no different in some circumstances than the M9 (and to a greater degree the M8), whereby a UV/IR cut filter may yield better results, depending on the subject matter.

 

Of course if it's prints you're assessing, then there are other variables like printer, inks, papers and profiles, etc.

Thanks for your replies. Jip, yes it's the latest firmware and I used daylight WB. Yes Jeff, I know there are threads on this. I did search the forum but didn't see this particular issue. I'd thought (mistakenly?) that the IR problem had been resolved with the M9. I'm viewing on screen. Anyway, will have a go at LR5 etc and see how that goes.

Set the camera to AWB and not one of the preset settings. Try LR and use the "auto" WB setting. Next, for the purple wires use the defringe option in LR. In LR you may want to desaturate the colors for this type of subject. Also, you just can't over expose any color channel; especially easy to do with red. IR is now a small issue with the M240, but so far in 6,000 photos it hasn't ruined anything for me. Color in the 240 with the latest update has been reported here by most to be good. Good luck.

Mostly, but not completely; a filter is sometimes more effective, but generally with synthetic fabrics..telephone wires more likely fringing, as Rick says. Nonetheless I don't use them, as I get the results I want with the M and LR, using the actions I cited.

Thanks Rick and Jeff. Will take your suggestions on board. I have the Scott Kelby book for LR5, so should have finished it in a couple of months if I start now;-).
In my experience, watching the various videos by Laura Shoe and Julieanne Kost is a faster and more effective way of learning Lightroom. You can find these with a google search. I would start with the videos on "What's new in LR5," because there may be some LR4 videos that have not yet been updated for LR5 — and by starting this way you can also watch LR4 videos, already knowing the aspects that have been improved in LR5.

You can keep CS3 as i do for tweakings but you need another raw converter. C1v7 does it for me.

 

do you know how to make custom profiles using capture one and a gretagmacbeth color card? I'm using LR5.2 which is ok but I would prefer C1

 

thnx

I just did what Capture One calls a "User Style" before the firmware update but i don't need it anymore. With the current 2.0.0.11 firmware, the M240 generic profile of C1v7 works fine if you choose the "linear response" curve and adjust afterwards in PS (in my case CS3).

I also have a question in regard to colours. I hope you will all indulge me...

I've only been using my M240 for a couple of weeks; and I have no experience with the M9.

 

My first event, was indoors and outdoors during the day, in natural light. The M240 performed magnificently; and minimal post processing was required.

My second event, was indoors for a friends wedding. I'm not happy with the colours. I confess, that it was partically my fault. I used a speedlight. Sometimes on camera, sometimes off camera. This had created a complex mixed lighting issue. which resulted in a few things (1) face glare / highlights. (2) orange oompa loompa skin tones (3) deep sea blue highlights in the hair.

 

Lesson learned, and will learn to adapt and control flash better in the future. Getting to grips with CTO's and gels and the like.

 

In the meantime, how do you postprocess your files on the M240? Any presets?
