Good!
Now please make a TTL/HSS or "hypersync" compatible with Sony!
Does Phottix Indra500 still CaNikon only?

In reply to:

naththo: I am waiting to see review on Spyder5 to compare with i1 Display Pro. i1 Display Pro blows away Spyder4Elite. Spyder is having hard time trying to beat against X-Rite.

Thats why my next device will be X-Rite cos I would like to see less banding on any monitor after calibration that X-Rite can do better than Spyder does. After Spyder Calibration, the banding got worse. Not good thing.

Glad to help, I told you Argyll+dispcalGUI is good... :)
The difference in contrast is because of the calibration device sensitivity not the graphic card, here I got more contrast by using the i1display Pro than the Spyder3.
I am curious about Spyder5 as they now mention 55% improvement in tonal response.

Naththo,
Argyll can not do miracles, but can do into the realm of real possibilities.
Looks like it is a TN panel, they are not good for photo works.
For photo works IPS family is the choice.
Darker blacks is important, but not high contrast...
High contrast deviates too much from the paper prints, see
https://luminous-landscape.com/why-are-my-prints-too-dark/

Good info about monitors for photo works at

In reply to:

Razor512: Most of these color calibrators, only have meter correction data for IPS panels with constant current driven backlights. Many of the companies do not mention in detail the panel technology that they cover, e.g., I purchased an x-rite colormunki, and it worked on an IPS panel that I have, but for TN panels, it had a horrible color cast,
Here is an example of what it does to TN panels. http://i.imgur.com/DKihSvN.jpg

In contacting the companies about this, they seem to be aware of it, but for both spyder and colormunki, even though they still manufacture them, they no longer support their products to the extent of expanding compatibility.
I was unable to return mine for a refund since it technically works, so if you buy one, know that you are taking a risk when it comes to compatibility. (they only specify compatibility in vague terms (LCD, and white LEG, or RGB LED backlighting; no mention of qualifiers such as PWM VS constant current, or TN VS IPS) (no support for PWM)

If it is TN or IPS does not matter, the main factor is the panel backlight like CCFL, WGCCFL, White LED etc...
I have an i1Display Pro(it is the same hardware, but not castrated to be slower) and can calibrate TN very well...
Maybe it is the monitor that is not good, TN monitors are cheap...
Anyway I do not use X-rite software, much better Argyll+dispcalGUI, see the tutorial
http://www.modelmayhem.com/forums/post/870355/1#post17806610
do not forget to select the proper correction matrix for the panel backlight.

NewsyL: What is stopping Datacolor/Xrite from offering ongoing updated correction matrixes to compensate for new back lights and LCD panels? I.E. in the manner of anti-virus software offering updated signatures for malware.

What will happen when OLED monitors become common? new hardware time?

The day OLED monitor is common the Spyders will be in the version 10 :)

In reply to:

Jan_Shim: I have the Spyder4 Pro and it has failed miserably in every recommended attempts to calibrate my dual Dell U2713H displays. These screens use GB-LED back lighting that's not natively supported by the Spyder4, and while their tech support has been helpful in recommending ways to calibrate, nothing worked. Not even calibrating via RGB channels. In the end, I resorted to Dell's factory calibrated sRGB preset for what seemed to be the best natural looking colours.

IF they are really for Spyder4 yes and if they are not the white balance will be off... The only way to know is to test...

The right device to calibrate the hardware of the Dell u2713H is an i1Display Pro because the "Dell" software is made by X-rite, see
http://www.tftcentral.co.uk/reviews/content/dell_u2713h.htm#hardware_calibration

If you want to do a software calibration, try Argyll+dispcalGUI
http://www.modelmayhem.com/forums/post/870355/1#post17806610
But you will need a correction matrix for GB-LED, maybe one of this

Naththo,
Try your Spyder4 with the free and excellent Argyll+dispcalGUI check the tutorial at
http://www.dpreview.com/forums/post/53534321
It is not only me, but *lots* of people prefer to use Argyll+dispcalGUI than the X-rite or Datasoft calibration software. If it is not your monitor fault Argyll+dispcalGUI may create less banding, also most of the monitors are made to work with “high” luminance levels, try to calibrate with +- 140 cd/m² and see if there will be less banding, higher luminance levels also helps the calibration device readings...

Philip Corlis: To Peevee1
#12 looks like Kodachrome to me. Good luck finding a digital preset to mimick it. Many have tried to simulate it but very few get very close.

IMO - this is one of the best approaches... http://www.defocus.net/2009/03/fun-with-the-dng-profile-editor.html

BTW - I think this exhibit is worth a trip from the states. Where else will you see all these great masterworks?

Kodachrome?

Prognathous, here OpenCL make no difference, but my graphic card is old/slow(nvidia GT240), best ask the support.

Yep, but I would like something more like the http://www.imaging-resource.com/PRODS/645D/645DhSLI0100_NR_OFF.DNG.HTM
that have a nice red fabric good to test high ISO/noise reduction and a bottle of Samuel Smith good to test moiré and demosaicing algorithms...
