Kodachrome 64 Preset - feedback needed!
May 5, 2012

Hi,

Warning - for users that don't have wide gamut displays the photos will just show a blown out red channel.

I've been working on an attempt for an automated Kodachrome 64 preset for RAW processing. I started with ACR 7/6.7 and LR 4.1, but as they really can't show the actual colours that Pentax DCU and Silkypix 5 Pro deliver I continued my work in Silkypix 5 Pro. It's a two step process tweaking WB, levels, contrast, microcontrast, etc. and then in the second step the colours are selectively adjusted by channels.

All my presets are 100% based on perceptual evaluation of the K64 colours from endless quantity of slides.

One of the problems is that the red channel is key to the K64 experience and it is really lost when converting to sRGB for the web. This is the reason why I post my samples in ProPhoto - viewers with wide gamut displays will be able to 100% evaluate the actual difference.

Please - I will really appreciate feedback on these as the preset is a bit raw in terms of selective colour tweaking per channels. It will really benefit from feedback of users that HAVE Calibrated Wide Gamut monitors and KNOW how Kodachrome 64 looks.

And to answer some questions - yes I know and have all the available plugins and the only thing getting close is RPP for MAC. Still it doesn't deliver well with the Pentax K-5 and Iliah, although promised, still is too busy to look for a solution. The second problem is that one has to keep a VMWare machine with MAC on his PC just because of RPP.

Sample 1 - actual Silkypix colours:

Sample 2 - actual Silkypix colours:

Thanks!

Have a great day/evening!

If there is anyone willing to work on this with me I will send more samples, colour checkers etc.

And I will of course share the presets in this case!

Cheers!

Yanko I am very impressed with your last PP the detail coming through the orange/red is excellent, its showing a lot more form and shape.

Hi,

Thanks for the feedback!

I forgot to add that both the Silkypix original and the K64 versions have been processed in terms of Kodachrome levels and contrast, clarity, etc..

My impressions regarding the Kodachrome Red are the same - it delivers a more 3d volume and punchy look. It actually also enhances the volume of the flower too as the red is deeper with much more contrast in the shadows.

Cheers!

That's really hard to tell…. to be honest I would say...
In reply to Yanko Kitanov, May 5, 2012

Just use DXo RAW and use their Kodachrome 64 preset I find it does seem to do rather well:

I have found that Dxo solves every color quip I had with the K-5- Yellows can be really yellow without green cast, greens look solid, blues look pretty solid and reds never go magenta land.

I am using normally now their film presets (Fuji astia, kodachrome or provia). Works like a charm.

Their normal default can work good too. Here's a photo ( a bit "too busy" though) that shows quite a range of different colors and to me they are all spot on.

I have yet to create a preset that I am 100% happy with for Kodachrome. (Lightroom) The problem I have always had is that if I get it right for one particular type of image and then apply it to another it doesn't translate. P.S. while I have a IPS monitor it is not wide gamut so that may have some bering

I do like what you have so far the flower conversion looks good.

Exactly - DxO colours may not be bad or may even be spot on, but they have nothing to do with the actual Kodachrome 64 colors.

The K64 colours were definitely not spot on. The reds are closer to ornage, a bot darker and less saturated, the blues have higher saturation and are much darker, the yellows are in the orange land and are a bit undersaturated, the greens are a bit more yellowish and are waaay undersaturated, etc., etc...

And nice photos - thanks for posting - I like your PP.

Cheers!

Hi,

Thanks - Now I have changed the preset already since I work with colorcheckers and I found that the reds of the car are a bit oversaturated and a bit too light, now they are a bit darker, deeper and a bit less saturated bringig them much closer.

I am close to getting a couple of presets that work well on many images - one is fr images that include skintones - the effect there is more subtle in the red channel, so that I don't get brownish lips. TYhe second effect is stronger and is perfect for landscapes and images with predominant red.

Thanks again!

Cheers!

One more sample
In reply to Yanko Kitanov, May 5, 2012

While I continue improving the preset here is one more sample:

Again - ProPhoto RGB, so it will be visible only for users with wide gamut displays, sRGB displays are too limited to display the actual colours and thus the differences, sorry. On sRGB displays these shots will look poor with blown out channels, etc.

Standard colours and levels:

Kodachrome 64 slide preset colours and levels:

Hi!

The shot was taken on the North-East coast of Sri Lanka, near at a fisherman's beach house near Trinkomalee.

These places were the scene for war. terrorism and a huge tsunami in the recent years, but still they remain a peace of Paradise...

Cheers and thanks for looking!

Ok to be clear what I mean is Dxo gives you the Kodachrome look (sort of). I haven't looked at too many slides. But yeah, the color will be a bit off and that's how the film was. I agree.

The K64 colours were definitely not spot on. The reds are closer to ornage, a bot darker and less saturated, the blues have higher saturation and are much darker, the yellows are in the orange land and are a bit undersaturated, the greens are a bit more yellowish and are waaay undersaturated, etc., etc...

And nice photos - thanks for posting - I like your PP.

My post processing is literally choosing the film emulation in DXo and play with global contrast just a tiny bit. I was suggesting, give Dxo a try and see if you can get the Kodachrome 64 look easier.

Cheers!

I have DxO installed and I use it sometimes (mostly for batch processing when lens correction is need and I don't have the time to go through each and every image) I have tried the film presets and I like the look it is just not Kodachrome - especially the reds are way of the original.

Portrait Sample
In reply to Yanko Kitanov, May 5, 2012

Here is the effect used with skin tones in the frame - as you see it doesn't effect the skin tone much and the subtle effect is quite often a benefit.

Again - for wide gamut monitors, it's simply invisible in sRGB and these photos look poor on sRGB monitors due to channel clipping.

Original colours:

Kodachrome 64 preset:

Presets
In reply to Wallace Ross, May 6, 2012

Having used LR for 3+ years - I wouldn't lean on presets. You can usually tell when someone is doing the old noob preset 'button-press' ... weird things like black grass, clownish/fake looking skin tones, shadow noise, and just a general 'fit' that has nothing to do with the image. Process shots individually - no two shots are the same (nor were two film frames); presets intended for one shot will always disappoint when applied to another.

Hi,

Thanks for your opinion! I absolutely agree with you on the level of jpg processing, but at RAW level the RPP for example uses quite consistently it's film presets and my Silkypix preset is also made to work universally on all shots.

Of course there is always the other question - although the preset can be applied to any shot, still it is quite clear that not every shot benefits from such presets.

Cheers!

Actually - the Kodachrome 64 was one of the slides that rendered volume very beautifully, due to its curves. The high contrast and clarity gave the slide a great 3d "pop". This of course went hand in hand with the narrower DR of such colour positive films.

Here is another fast sample - the whole frame feels a bit more 3d even at such small sizes:

I only shoot RAW; presets on JPEGS are even less of a good idea. Presets = what you do when you don't know how to process. When/if every shot you take has the same exposure, color, focus, etc. .... then your presets will work "universally". Give it some thought.
