You look at one of my mineral photographs on your phone, and its color looks a certain way. Then you open the same image on your computer, and the color has shifted. The blue is deeper on one, the green more vivid on the other. You are not imagining it. The image has not changed. The screen has.
What I control on my end
Every screen builds color by mixing red, green and blue light, and no two screens do it the same way. The panel technology, the brightness, the color temperature, the factory settings: all of it shapes what you see before your eyes ever reach the image itself. The same file, opened on three devices, becomes three slightly different photographs.
Phones are the worst offenders, and they are the worst precisely because they look the best. Most modern phones push brightness, contrast and saturation hard, because a punchy image sells a screen in a store. It looks spectacular. It is also unreliable, because what you are seeing is not the color in the file, it is the color the phone has decided to show you.
And almost no screen is calibrated. A few professional monitors are. The vast majority of phones, tablets and laptops in the world are not, which means each one drifts a little in its own direction. Your devices are very likely showing you different versions of the same photograph right now, and none of them asked your permission.
What I control on my end
I cannot calibrate your screen. I can calibrate mine, and I can control the file I hand you.
I work on a high-quality BenQ monitor, and I calibrate it with a Spyder probe placed directly on the screen. I do not trust my eye for this, and no one should. The eye adapts, the eye forgives, the eye lies. A calibration probe measures what the screen actually emits and corrects it against a fixed standard. So when I judge the blue of a cornetite or the green of a dioptase, I am judging it against a reference, not against whatever my particular panel feels like showing me that day. The color I approve is a true color.
For that reason, I deliver in sRGB. There are wider color spaces that hold richer, more saturated colors, and on paper they sound better. But they carry a trap: on any device that does not manage color properly, and most do not, a wide-gamut image comes out wrong, often oversaturated and garish. sRGB is the common language nearly every screen and browser understands. Delivering in sRGB is how I give the largest number of people the closest thing to what I actually saw.
Beyond that, I also print, regularly, and not only when a client asks for it. Paper is honest in a way a backlit screen never is. A screen can hide a color problem behind its own glow; a print shows it plainly. Printing my own work keeps my eye calibrated alongside my monitor, and it catches any drift before it reaches a client. When I deliver, I match the file to its destination: CMYK for print, JPEG or WebP for screen, chosen for where the color will finally live.
The honest part
Even with all of this, the photograph on your uncalibrated phone is not exactly the photograph I approved on my calibrated screen. I have done everything on my side to make the mineral photograph color true and to make it survive the journey. But once the image lands on a screen I have never seen, one that runs bright and saturated by default, some shift is unavoidable. That is not a fault in the photograph. It is simply how screens work.
And it points to something I think is worth saying plainly. No image, on any screen, is the specimen. What I make is the most faithful record I can: shot under controlled light, with the color measured and managed as carefully as the tools allow. My photograph is the best possible representation of the piece, but it is not the piece itself. Nothing on a screen ever will be, and it was never meant to be.
That is the standard I work to. Everything I can control, I control. The rest, I tell you honestly.
