I got a screen calibrator thingie.

I'm starting to edit photos for actual clients and if they are going to be printing any of these images I have to make sure my display is as accurate as possible.

I went through and looked at all of my recent edits to see if any of them were egregiously out of whack except for that one weird photo of the red baby that seems to only be red on my Samsung phone. Thankfully everything else looked close to how I intended. So that is a relief.

Color accuracy used to be a much worse problem. In the old days you could look at identical displays from the same company and they would have completely different colors. But now with the exception of the cheapest of the cheap, every display in the last 5 years is calibrated at the factory. Though TVs are a mixed bag because the "standard" or "vivid" modes are usually set as default so they stand out in stores and most people don't know to change that to the cinema or movie mode to get the accurate colors.

Oh, and did you know the ambient light can affect color accuracy too? So if you aren't looking at my images in a darkened room then your eyeballs could be seeing them way different than my intentions.

Makes me want to pull my hair out.

From now on you all have to come over to my house when I publish an image. We'll have a little viewing party and I will bake everyone cookies and we'll head to the basement and turn out the lights and you can be all, "That baby is the perfect amount of red."

I think going forward I will adjust according to my calibrated screen and if my colors look funky on your device I can just say, "Not my fault, Datacolor Inc. says your screen sucks. Deal with it."

Actually, I would like to get an iPhone as a reference display.

Combined with my Samsung phone, I'd be able to see how my images look on ~80% of smartphones. And I could be reasonably sure my colors are decent for the majority of folks who see them.

But iPhones be spendy so that will have to wait, as my finances took a sudden infuriating turn recently. But hopefully I can keep getting clients to help me stave off homelessness. You'd think close family would be concerned about something like that. I think I'm just going to choose my family from here on out.

Wow, this post about colorimeters took a dark turn.

BenQ PD3225U：A Mac-friendly creator display that outclasses Apple's own

Designed for creative professionals, the 32-inch BenQ PD3225U monitor ($1,099.99) is primarily geared to Mac users, though it works well for Windows PCs, too. The PD3225U is brighter than its predecessor, the BenQ PD3220U, and its contrast ratio is much improved over that Editors' Choice winner. It's also more cost-effective than Apple's own Studio Display while including a larger screen and more versatile stand. All of this makes it our new Editors' Choice pick for 4K creative pro monitors.

The PD3225U's 31.5-inch, 10-bit IPS panel has a 4K UHD resolution (3,840 by 2,160 pixels) at a 16:9 widescreen aspect ratio. The pixel density works out to 140 pixels per inch (ppi), which is more than adequate for work with finely detailed images and intricate illustrations, though not as high as some professional monitors with smaller screens. The Apple Studio Display, for example, has a 27-inch screen with a 5K resolution (5,120 by 2,880 pixels) and a pixel density of 218 pixels per inch.The PD3225U uses LG's IPS Black technology, an in-plane switching variant that doubles the contrast ratio (to 2,000:1) of standard IPS panels. While IPS Black can't compete with OLED's effectively infinite contrast ratios in which groups of pixels can be turned off, achieving a "true black," it produces considerably deeper blacks than standard IPS.The panel fits in a matte-black cabinet, which measures 24.7 by 28.1 by 10.8 inches (HWD) with the stand fully extended and weighs 18.1 pounds. The gray base has a large 8.5-by-11-inch footprint, and a sturdy shaft extends upward from it to connect to the cabinet.Despite being a Mac-friendly monitor, the PD3225U plays well with Windows computers, unlike the LG UltraFine 4K Display (24MD4KL-B), which we don't recommend for use with Windows PCs. And unlike many other Apple-friendly third-party peripherals, the PD3225U does not try to emulate the Mac aesthetic in color or design. Nor does it have egregious upsells. The Apple Studio Display's base model's stand is limited to tilt adjustment, and for an extra $400, you can get a stand with both tilt and 4.13 inches of height adjustment. The PD3225U, in contrast, includes a stand that supports height, tilt, swivel, and pivot adjustment.The PD3225U includes the HotKey Puck G2 controller, which we first saw in the PD3220U. It sits in front of the monitor, to which it's connected by a USB cable, and has three programmable buttons plus a Return button. It adds a knob on top that, by default, lets you adjust brightness. Rotating the knob lets you cycle through all of the OSD's settings. Picture modes are abundant, among them DCI-P3, Display P3, HDR, sRGB, Rec. 709, CAD/CAM, Animation, Low Blue Light, Darkroom, M-book, DICOM, and User. Display P3, a color gamut that Apple designed, is the native color space for most recent Macs.Using the HotKey Puck G2 to control the PD3225U's on-screen display (OSD) settings is more convenient than doing the same by reaching behind the monitor to manipulate the joystick controller.Connectors include two HDMI ports, one DisplayPort 1.4 port, and two Thunderbolt 3 ports. One Thunderbolt port is upstream, which supports DisplayPort over USB Alt Mode and provides up to 85W of power delivery, and one is downstream, which provides up to 15W of power delivery; through the Thunderbolt-out port, you can daisy-chain a second monitor.The PD3225U also includes a USB-B and a USB-C port (both upstream) and three downstream USB-A ports. The USB-C and one USB-A port are side-facing for easy access, and so is an audio-out jack.The PD3225U includes a pair of 2.5W speakers, which demonstrated passable sound quality and volume typical of monitor speakers in our testing. The audio-out jack can be used for headphones or powered external speakers.I tested the BenQ PD3225U's brightness, contrast ratio, and color coverage using our standard test gear: a Klein K-10A colorimeter, a Murideo SixG signal generator, and Portrait Displays' Calman Ultimate for Business calibration software.BenQ rates the PD3225U's luminance at 400 nits (candelas per meter squared), and in our standard dynamic range (SDR) testing, its best score was just short of that, at 371 nits. As an IPS Black monitor, its rated contrast is 2,000:1, and it bested that in our testing with a 2,236:1 measured contrast.We normally test brightness and contrast in standard (or default) mode without changing any settings, except for setting the brightness to 100%.

Laboratory Equipment: Essential Tools for Research and Development

Microscopes are indispensable tools for laboratories as they enable researchers to see structures and features too small for the naked eye. Different types of microscopes like compound, stereo, and electron microscopes allow examination of cells, tissues and various samples at different levels of magnification. Compound microscopes have interchangeable objectives and ocular lenses that provide low to high magnifications from 40X to 1000X. Stereo microscopes give low magnifications from 6X to 120X and are ideal for viewing three-dimensional samples. Electron microscopes have resolutions down to the nanometer level and are crucial for cellular and molecular analysis. Microscopes continue advancing with techniques like fluorescence and confocal microscopy for live cell imaging. Laboratory Equipment: Pipettes and Dispensers Handling small liquid volumes accurately is critical in many experimental procedures. Pipettes available in various fixed and adjustable volumes are used to transfer samples, reagents, drugs and more between tubes, plates or vessels. Manual pipettes come in single channel and multichannel varieties for quickly dispensing set volumes. Electronic pipettes automate repetitive pipetting with adjustable speed and greater reproducibility. Dispensers are also available for liquid handling, dispensing adhesive liquids, organic solvents and even highly viscous materials. Automated liquid handlers are large capital equipment that can pipette thousands of samples in parallel for high throughput experiments. Centrifuges Centrifugation is a fundamental separation technique used across all types of laboratories. Benchtop centrifuges are simple bi-phasic models suitable for routine pelleting of cells, small particles and precipitates. They provide RCFs (relative centrifugal forces) from 1000 to 12000g. Preparative centrifuges have larger rotors and capacities for voluminous sample processing. Ultracentrifuges enable high speed sedimentation by developing enormous RCFs over 100,000g. Models for ultracentrifugation employ zonal, swinging bucket or fixed angle rotors depending on the separation goals. Selecting the right centrifuge based on sample type, size and desired separations is key for optimizing results. Laboratory Equipment: Spectrophotometers and Colorimeters Quantifying analytes through detection and measurement of light absorbance or transmittance is done using spectrophotometers and colorimeters. They are indispensable in analytical chemistry, biochemistry and molecular biology labs. Single beam spectrophotometers detect absorbance of a sample against a blank reference. Double or triple beam instruments allow simultaneous measurement of multiple samples and references. Colorimeters are compact single wavelength devices ideal for dedicated absorbance assays. Modern multi-mode readers combine varied features like fluorescence, luminescence, absorbance in a single box for versatility. Automated instruments speed up high throughput absorbance measurements in microplates. Advancements in detector and optic materials continue enhancing sensitivity and accuracy. Laboratory Equipment: Water Purification Systems Pure water is imperative for numerous analytical procedures and as a solvent in chemical reactions. Laboratories install point-of-use or centralized water purification systems to generate different grades of water for their needs. Reverse osmosis systems yield high purity water from tap or well sources. Ion exchange columns further polish RO water to Type I standards. Advanced systems integrate UV oxidation to minimize microbial growth and sub-micron filtration for generating ultra pure or Milli-Q water. Water qualities are certified through resistivity, TOC and particle testing. Laboratories also require simple dispensers of purified water right at the bench. Mobile cart-based purifiers deliver purified water anywhere as needed. Integrated systems optimize space and centralize management of water purification.

I really hope that phrase "it takes money to make money" is true.

I have started taking photo editing gigs. But in order to do them properly I had to purchase some tools to help me.

I got an advanced colorimeter to calibrate all of my displays so I don't have to check my edits on 9 different screens to make sure they hold up. Plus I assume most of my edits will be printed out and you cannot send something to print without an accurate screen.

I mean, you can. There isn't a law against it. But if you want the image on the screen to look anything like what spits out of the printer, ya gotta calibrate.

And I had to buy a $70 software license because I need a single filter Photoshop does not offer. It removes the textured pattern in scanned photos and there is literally no other way to do it.

I feel like I just bought this tool kit...

But I will only be using the smallest Allen wrench.

So the two jobs I've been hired for will amount to $0 in profit.

But I will have these tools available for future jobs and they are only a one-time expense. I just have to make sure these aren't the only two editing gigs I ever book.

With ongoing technological advancements, luminance meter will continue to play a significant role in providing us with better lighting and display experiences. The Basic Principle of a Luminance Meter A luminance meter primarily utilizes a pair of light apertures located at a certain distance to receive a fixed solid angle and fixed light flux. This value does not vary with the distance of an object, as long as the surface area of the object is sufficiently large. In order to be able to target the object being measured, an imaging system is commonly used. The measured light source is imaged on the reflecting mirror with a hole (front aperture) through a lens. Part of it is received by the human eye through the reflecting mirror and eyepiece for targeting and monitoring, ensuring that the imaging plane is aligned with the reflecting mirror. The other part of the light passes through the small hole on the reflecting mirror and reaches the V(λ) receiver through the rear aperture. The brightness value is displayed using a pointer or numerical table.  A luminance meter is a commonly used instrument for measuring light and color, widely applied in fields such as chemical analysis laboratories. It measures brightness by utilizing a pair of light apertures with fixed solid angles and fixed light flux to receive light flux. The basic principle is that when the surface area of an object is sufficiently large, the numerical value of received light flux is not influenced by the distance of the object. In order to target the object being measured, an imaging system is commonly used for imaging and monitoring. The brightness value is displayed using a pointer or numerical table.
