Last fall, I got myself a new fancy 27", LED-lit, IPS, WQHD monitor. A really bright, color-accurate, calibrated beauty! Unfortunately, it allowed me to see some of the horrific post-processing choices I was making on my old, fluorescent-lit, TN LCD monitor that was best suited for coding and word processing. I had a feeling of "everything I've ever posted is crap" come over me and caused me to pause and take a timeout from posting on Flickr.
This is one of those shots I recently came across and felt compelled to give it a little better "treatment". There is nothing particularly special or interesting about this shot, other than it was taken from MSP tower, but seeing the old version spurred me to write this little blog post.
Nowadays, I try to keep my monitor calibrated using the x-rite i1 display profiler. That said, just because "it looks good on my monitor" doesn't mean I won't make more bad post-processing choices in the future. Everyone sees these photos through the "eyes" of a different monitor with different color temperature, depth and saturation, black levels, brightness, contrast, gamma, sharpness and resolution. And though the end result is most often subjective, at least now, I feel I have a good basis for what you're seeing.

Phone sitting on enlarger lens with digital negative of a Fuji Velvia slide
- I use GIMP to make my negative, and adjust contrast, generally making 3 versions with varying contrast so if I need to dial up or down, I just swipe to the next image. I put a black border around the images so I can zoom out or in as required on the phone screen.
- I put my 3 images on google photos from my computer and then load up google photos on my phone, just ease of use, and can zoom in and out on the screen to make it the right size for the enlarger
- turn the phone on full brightness, screen saver off, airplane mode (no interruptions)
- I cut a piece of thin foam mat with a square hole for the phone to sit on. This stops it from moving around, and also the foam does not activate the screen. If I just put the phone on the metal of the enlarger the phone will start doing strange things, like you have a bunch of fingers on the screen. The foam mat fixes this.
- focus and size on the enlarger is as normal, adjust height for size and adjust focus below to get a sharp image. When you check with the focus loupe you can actually see pixels
- the enlarger red filter is my shutter, I swing it back and forth and count seconds, the phone is always on. This image was 5 seconds.
note : once I scan the print at 1200 dpi and then zoom in I can see the phone pixels in the image. But when I look at the 8x10 print with my naked eye I cannot see any pixels. My phone resolution is called WQHD 2560 x 1440. I am not sure how much of a difference a lower resolution display would make.
When it comes to wide color gamut LCD monitor supporting 99% AdobeRGB, which monitor calibration tools perform better, X-rite i1 Display Pro or Datacolor Spyder4?
Quick test result as following:
At 140 Luminance (personal preference), manual calibration with software included in retail package and calibration measured at the center of monitor specify by the software:
I1 DisplayPro: x=0.313, y=0.329, T=6464K, Lv=141
Minolta CS-200: x=0.3214, y=0.3288, T=6044K, Lv=140.57
--------------------------------------------------------------------------------
Spyder4: x=0.313, y=0.328, T=6472K, Lv=140.2
Minolta CS-200: x=0.3053, y=0.3226, T=7004K, Lv=135.07
The above dataset demonstrate both colorimeters are capable but i1 DisplayPro performs better on wide color gamut LCD monitor like Dell UltraSharp U2713H, 2560 x 1440 resolution supporting 100% sRGB and 99% AdobeRGB.
-------------------------------------------------------------------------------
However, Dell U2713H also ships with an unique software (co-develop with X-rite), UltraSharp Color Calibration Solution software that will pair with i1 DisplayPro to significantly improve the calibration accuracy:
Target Chromaticity: x=0.313, y=0.329. 6500K, Lv=140.0
Cal 1 sRGB:
Minolta CS-200: x=0.3142, y=0.3292, T=6431K, Lv=139.09
Cal 2 AdobeRGB:
Minolta CS-200: x=0.3149, y=0.3296, T=6389K, Lv=143.14
At such a relatively lower price point of a 27 inches monitor with 2560 x 1440 resolution and 99% AdobeRGB, the bundling of Dell color calibration software and i1 DisplayPro offer a very high color calibration accuracy with exceptional value on price/performance!
Highly recommend:
- Dell U2713H (ships with Dell Color Calibration Solution Software)
- X-rite i1 Display Pro
Color calibration accuracy per the tested copy:< <1% Chromaticity value!!
