![]() ![]() If it does not, then RawTherapee failed to decode this information correctly. The info panel should show your camera and lens names. To check whether the camera and lens names are decoded correctly, open a photo and in the Editor tab hit the " Quick info" button. This information is decoded from the photo's metadata (currently using a home-made solution, and in the future using Exiv2). In order for RawTherapee to be able to automatically query the Lensfun database, RawTherapee needs to know which camera and lens was used to take a given photo. The tools "Profiled Lens Correction" and "Perspective" rely on data from Lensfun to simplify and automate the work of specifying the right camera/lens information and finding the optimal correction parameters. You can find more information about it in the Lensfun FAQ. Lensfun is an open-source project which contains a database of lens parameters. There are two sources for this data: Lensfun and Adobe LCP. Some of these sub-tools are capable of performing their function in an automated way with a single click by relying on data which describes the imperfections inherent to a given camera and lens. Do as the camera does: correct the distortion, and the dark corners disappear It is not possible to fix the dark corner issue by using vignetting correction - there is no information about the scene in those corners, the scene is occluded by the lens mechanism/lens hood. When you view a JPEG image from these cameras the distortion has already been corrected in-camera, so owners are often unaware that the problem existed in the first place and are surprised to find that the raw image shows these dark corners. The way these cameras deal with these two problems is by correcting the distortion, as a result of which the corners of the image get "pushed out" beyond the frame, thereby hiding the corners darkened by the lens or lens hood. Typically the same cameras have lenses which suffer from strong distortion. Some cameras, typically small ones - compacts, bridge-type and even mirrorless - will capture parts of the lens hood or lens mechanism in the corners of the frame. They allow you to fix errors and distortions which derive from imperfections in your camera gear, such as lens distortion and vignetting, as well as to improve issues deriving from the placement and adjustment of your camera, such as an uneven horizon or perspective distortion.ĭo not confuse vignetting with a blurry lens hood being visible in the corners of your image. This tool comprises of several sub-tools which share common adjustment parameters. 2.1.4 Updating your Lensfun database in Windows.2.1.3 Updating your Lensfun database in Linux.2.1.2 How to check whether your Lensfun database contains information about your camera/lens.2.1.1 How to check whether your Lensfun database is intact. ![]()

![]() There are tons of Charlieplexing Instructables, you can read about its theory here. If you switch between the LEDs really fast, the persistence of vision will make them look like they’re all on. As the LEDs turn on only when they have voltage on the anode and ground on the cathode and do nothing in any other situation, it is possible to connect a lot of LEDs to a small number of microcontroller pins in all the physically possible ways and turn them on one by one, turning one pin high, one low, and keeping the rest in input mode. These pins can be active high, active low and passive (aka input, or high impedance state). These techniques are often mixed up, but, while their basic principle (persistence of vision) and their end result are relatively the same, the ways they achieve this result are fundamentally different, and it is important to understand the difference right from the start to avoid confusion later.Ĭharlieplexing relies on the tri-state nature of the microcontroller pins. There are two main techniques employed when multiplexing LEDs. There is a certain wow-factor, however, so some fun will be provided. With these two projects, I’m trying to help better understand the ways multiplexing, timers and interrupts work. There are better ways to control multiple RGB LEDs off an Arduino. Please note that this Instructable is educational, not practical. 1 demux chip, either 74HC138 or 74HC238 3 or 8 MOSFETs, P-Channel or N-Channel respectfully 6 or 16 RGB LEDs, either common anode or common cathode So, to test the stuff explained here, you’ll need: It’s very easy to switch between the N- and P-Channel MOSFETs, provided you also use a different type of LEDs and demux chip I’ll give the details. But, alas, I have only three P-Channels MOSFETs in breadboard-friendly packages. In most cases, you should stick to the first pair while dealing with LEDs, as all the LED drivers are current-sinking devices. The first project will be common-anode LEDs and P-Channel MOSFETs, the second one will use common cathode LEDs and N-Channels. The first one drives 6 RGB LEDs using just three MOSFETs the second one drives 16 LEDs but needs eight MOSFETs and a demultiplexing chip. And to do this, I built a couple of devices that use the bare minimum of hardware between the Arduino and the RGB LEDs to make the clearest possible picture of how the multiplexing works. ![]() There are a lot of Instructables dealing with multiplexing, but most of them describe the particular project and do not cover the basics I decided to amend that. There are multiple ways to light a lot of LEDs off an Arduino (or any other microcontroller): shift registers, LED drivers, programmable LEDs, but the more LEDs you want to control, the closer you’re getting to the multiplexing: the ultimate technique for driving hundreds and thousands of LEDs. ![]() ![]() Have you been waking up at 5:55 in the morning? Or perhaps you just happen to glance at the clock right at 5:55 in the evening? Let's look at the meaning of the Angel Number 555. So, when you notice a number sequence at a synchronistic time, or you keep noticing the same number repeatedly, pay attention to what you're thinking about and what is happening around you to help you decipher your message from spirit. With awareness, and by tuning into the vibrational meaning of numbers you can learn to decipher and receive the guidance from the angels present within the numbers you're seeing. ![]() ![]() Numbers are a simple and straightforward way for angels to deliver messages that aren't filtered out by the ego mind. Today I want to talk about a powerful angel number that heralds the possibility for massive change and transformation.īut first… Why Do The Angels Communicate Through Numbers? The reason I am writing about so many angel numbers on this site however, numbers like 333, 444, 222, 1111, and 1033 is because the angels are bringing these numbers to so many people's attention. Whenever you repeatedly see a number sequence, there is a good chance it may contain guidance from your team of guides and angels supporting you from the realms of spirit.ĭon't worry if you're not yet seeing number sequences though, because numbers are simply one of many signs and signals the angels use to communicate their guidance and illustrate their presence in our lives. ![]() Seeing the Angel Number 555 is a sign of big potential for change and transformation… ![]() ![]() What are the essential V60 Coffee Brewing tools?

The mission was expanded in 2012 to include providing effective community supervision of adult members of the correctional process to ensure public safety based upon the transfer of probation and parole supervision and community correction grant program functions from the Board of Parole (BOP) to the TDOC. Members of the public are allowed to write-to and visit persons in custody, offenders, criminals, arrestees, and view mugshots at the detention centers, county jails, and police departments. The department’s mission has always been to operate safe and secure prisons to enhance public safety in Tennessee through incarceration and rehabilitation of felony offenders. Results include mugshots, arrests, charges, booking number, jail location, visitation hours, charges and more. Our only system includes the lookup of inmates within our prison system. We are very proud of this award and aim to renew our efforts year after year. ![]() ![]() Since then, each part of the County Jail and State Corrections system has been re-accredited in a three-year cycle by the American Correctional Association.
