F.lux
Automatically adjust your monitor settings to reduce eye strain

F.lux is an unusual tool which can automatically adjust your monitor's colour temperature to try and reduce eye strain.

Why bother? The theory is that computer displays are normally set up to display a harsh, blue light. This works fine during the day, but is too bright for night viewing, and could even promote sleep problems.

To avoid all this, F.lux uses your location, the date and time of day to figure out your sunrise and sunset times, then automatically adjusts your monitor's colour temperature to a more appropriate level.

To see what this might mean, click the blob representing the sun in the program's Settings dialog for a quick preview; it'll be at normal brightness levels during the day, but change to warmer, more orange/ yellow glow at night.

Click "Change Settings" and you can further customise the program to better suit your needs, by more accurately setting your location and deciding how quickly you want the colour temperature change to occur (it's annoyingly fast by default, but setting to "Slow" here will help).

And you can also adjust the colour temperature you'd prefer at day and night, but unless you're extremely sure what you're doing we'd recommend you try out the defaults for a while, first. The preview will show you what looks like a very extreme change, but in part that's because you're viewing it quickly, and all at a single time of day: it works much better in real life use.

F.lux won't be right for everyone. If you work both day and night at the same computer, though, in the same place, then it could be an effective tool. And the program includes no adware or other complications, so you can install and try it out without any hassles or problems.

Version 3.10 brings:

1.f.lux can go warmer than 3400K now, down to 2700K. Or even 1200K if you really want it to.
2.Support for color profiles from a hardware calibrator
3.Movie mode. This setting warms up your display, but it preserves shadow detail, skintones, and sky colors better than f.lux’s typical colors. It lasts 2½ hours, which lets you watch most feature films
4.Disable until morning, for late-night crunch mode
5.A new “darkroom” mode, which inverts colors and gets very red
6.A map to help you find your location
7.Hotkeys to dim your display (Alt-PgDn, Alt-PgUp) late at night, so desktop users can dim too
8.A hotkey to disable/enable f.lux quickly: Alt-End
9.If you have a laptop, f.lux gets warmer when your backlight dims, like an incandescent lamp
10.A simple schedule for Philips Hue, so you can f.lux your house

Verdict:

It won't work for everyone, but in some cases F.lux really can make your monitor more comfortable to view

Spektrel Art 1.0.0

Free Full Commercial Software

Spektrel Art is a stand-alone program and Photoshop plugin which transforms digital photos into "magical art that glimmers and gleams with intersecting lines of tapered light".

What does that mean? Essentially it applies a configurable mix of effects, enhancing edges, smoothing backgrounds and emphasizing colours. Take a look at the thumbnail for one example, and the official product page has more.

Spektral Art works much like any similar tool. Open an image, click one of the thumbnails to apply a particular preset, or click a few buttons and drag some sliders to fine-tune the results.

There's surprising scope for variation, too. For example, just switching from the "Light" to "Dark" theme can transform a bright and friendly image into something dark and sinister, at least in some cases (results vary depending on the source image).

Please note, the demo version doesn't allow images to be saved.

SPECIAL OFFER: as we write, the developer is offering Spektral Art for free. The offer expires August 29th. Please note that you must provide your name, address and phone number to receive your free license.
