Feedback on vignetting model

After going through the exercise of creating lens profiles to corect the vignetting inherent in wide-angle pinhole photos, I thought I'd offer some feedback on the data model.  Not a complaint, just an observation.
The model requires the vignette to be represented as the coefficients for 2nd, 4th, and 6th degree terms in a polynomial.  This representation offers a very close approximation of real falloff for moderate ƒ/Dmax ratios, but cannot represent the *actual* falloff and the approximation gets increasingly poor as the ratio shrinks.
Here's a graph of the actual falloff as expressed by the function y = 1/(((d/ƒ)^2)+1) graphed against the representations created by the Lens Profile Creator, which offers a handy tool for fitting the curve (click it to see it bigger):
The first curve is a hypothetical 6x6cm frame with a "normal" 80mm focal length, as if one converted an old 6x6 film camera to pinhole.  The approximation here is fantastic.
The second is my 6x12cm pinhole camera with a 40mm focal length.  This is fairly common; both my $480 Zero 612F and the $50 Holga 120WPC use this combination.  The fit here is pretty good, but it's a good thing the frame isn't any wider.
The last is a relatively common large-format pinhole ratio, with a 25mm focal length on 4x5" film.  The Zero 25B uses this combination..  As you can see, the model is quite poor at representing this curve.
Since the actual falloff due to distance can be expressed by the simple formula above, it's too bad it can't be represented precisely.  Maybe if someday there's a v2 of this specification...

That would help, but not nearly as much as a hybrid approach -- allow all photos to get corrected using a mathematically proper model following the 1/(((d/ƒ)^2)+1) formula, *in addition* to a polynomial correction to account for other vignetting factors.
All photos taken with a flat sensor or film have a falloff curve that matches that formula, though in the "normal" case the effect is quite small.  (Does it get screwed up at large apertures or with funky lens designs like retrofocus lenses?  I'm not enough of an optics guy to figure that out without devoting some serious mental energy, and it's too late at night for that right now.)
No additional tags would be needed in the profile -- in most cases you already know the focal length and frame size, which is all you need to calculate it.  You could have a boolean tag for whether to perform that correction or not I suppose...

  • Feedback needed on modelling methodolgy in Brillien container

    All,
    There's a new initiative called Brillien which is intended to be a new way of modelling/developing enterprise applications. It emphasizes Flow over Structure and tries to get rid of plain (association based) structures which is very common in (java)containers. Besides the new way of modeling it , of course, provides thread- and object pooling, DI and so on.
    Would you please read and comment (pros and cons are both appreciated) the stuff on the following links:

  • OWB Implmentation Model Assistance

    We have developed an implementation model which segments development design from production design into two design repositories. The method of moving to production is Metadata Export/Metadata Import between the two design repositories. The development design deploy to development runtime for testing etc, and the production design can deploy to production runtime for production release. Our primary consdierations are: Auditing: Change Manager is applied at design not runtime, and if we had both development design and production released projects in a common design repository, then we could get a complete snapshot of what exactly comprised production at any given moment. Also, we wanted to reduce the potential that something would accidentally get deployed to production, which is a true possibility, as in the design, the connection screen for the deployment, comes up for the most recent deployment repository selected, and the user isn't forced to select which deployment to deploy to each time. Another consideration is that when upgrading the software, we did not want to apply upgrades to both development and production at the same time, so this model enables us to apply upgrades strategically. The original strengths of sharing objects across projects still exists with this model. And it the only necessary work in moving a project to production is re-registering the Data Sources and Targets to their production locations. What I would like is for anyone who has implmented a similar model to provide feedback on this model. I would really like Mark Van Der Wiel to look at it too or another Oracle resource in his place. Thanks for all of your help.
    If you are interested in helping, please send me an email at [email protected] and I can email you my model, as I am not able to upload it here.

  • New Advanced tab for Calibration-how to use properly?

    Dear Adobe and Lens profilers,
    I have just used the newest Lens Profile version and noticed the new "Advanced" tab on the right beside "Calibration".  There are lots of choices for rectilinear, fisheye, distortion, etc.  I need information on how to use the advanced tab - I do not see updates to the user guides that are available that address this new tab. For example, there are "one parameter radial distortion" up to five parameters for various items, there is a sensor pixel shape choice - could someone from Adobe please address and explain these choices and how to properly set them for use,(including the vignette model and principal point choices, and all of these).
    Thank you,
    Debra

    Hi Debra, in general, the higher the number of parameters, the better the potential for correction (especially for full frame cameras). For example, the three-parameter radial model in some cases will do a better job than the two-parameter radial model. I have not found cases yet where the 5 parameter (radial & tangential) model is helpful. As you can see, the default option is Auto which means Lens Profile Creator does an internal comparison of which model works best for your provided measurement data, and picks the appropriate model automatically. (This is largely why it is not necessary to fiddle with the Advanced settings.)
    When you find cases where Lens Profile Creator is not building a satisfactory profile, my experience has been that the common issues cannot actually be addressed by using the Advanced settings. For example, if the profile is slightly overcorrecting for vignetting, changing the Vignette model parameters in the Advanced section often does not help. (This does not mean that future versions of ALPC won't provide other ways to deal with it. It just means that for now ALPC does not provide a direct means by which to tweak a profile that is slightly off.) If you are using Camera Raw or Lightroom, my suggestion is to use the "Correction Amount" sliders beneath the profile selection to adjust the correction. In the vignette overcorrection case, instead of using the default value of 100, dial it back to 80 or 60 (as an example)

  • New MX922 Setup, nothing but blank pages - communicates fine with computer

    I purchased and installed a new Pixma MX922 printer and connected it wirelessly to my home network.  Went through install, put in the ink cartridges (all light up) and attempted the print head alignment -- page came out blank.  I attempted this several times with sheets provided, same result.  Then tried the manual alignment, same result, blank page.  I have verified that the cartridges do not have any plastic left covering dispenser or air supply. I looked inside to make sure no protective covers remained (somewhere specific I should look?).  I installed the software on a laptop and connected and attempted to print, only a blank page.  I also connected via USB cable and ran Diagnose tool, didn't find any problems.  The feedback on this model is favorable, what am I missing?

    Hi bbgunwb,
    Performing a series of cleanings and deep cleanings on the printer may resolve the issue you are experiencing.  Prior to performing the cleanings, please turn off the printer, unplug the power cord from the back and leave it out for at least 10 minutes, then plug it back in and turn the printer back on.  Next, please follow the steps located at the link below to perform the print head cleanings:
    PIXMA MX922 Print Head Cleanings
    If ink still does not print on the page after performing at least one cleaning and two deep cleanings, or if you are unable to perform the print head cleanings, the printer will require servicing.  Please call or email us at one of the methods on the Contact Us page to obtain your servicing options.

  • Surround Sound Question

    what is the best surround sound system w/ towers and that will support xbox 360, ps3 and tv all at the same time, and for the best price

    Hey themarine472,
      Honestly, the answer to your question is really dependent on what you’re looking for in a home theater system.  Before anything else, you may want to ask yourself the following things:
      1)    How many speakers do I want?
    2)    What kind of connections do I need?
    3)    Do I need an upconvert DVD player?
    4)    Do I have a brand preference?
      For starters, you’ll probably find that most common home theater system configurations will consist of two front channel speakers, two surround speakers, one center channel speaker and one subwoofer.  Other configurations do exist, but the difference in price between four, six and eight-speaker systems can often prove to be quite significant.  On the other hand, you aren’t necessarily limited to buying bundled packages.  Most retailers, including Best Buy®, will sell individual components so that you can pick and mix your speakers.  Keep in mind though that there is a trade-off for being able to do this: purchasing individual components often proves to be much more expensive than buying pre-packaged bundles.
      Next, you’ll need to know what kinds of cables are used to connect your video game consoles to your TV.  Most newer video game consoles will make connections for audio signals using digital optical or HDMI cables, but it’s recommended to double-check yours just to be safe.  Once you know the cable types, you’ll probably want to look for a home theater system that has the same kind of inputs.  For example: if you want to use HDMI cables to connect both your PS3 and Xbox 360 to your TV, the receiver should have at least two HDMI inputs.
      Then the question becomes whether you should purchase a system with an upconvert DVD player.  A good number of home theater bundles will include one of these players, which is great if you have an HDTV and want to watch older movies in a higher resolution.  The downside however, is that whenever the player itself (or one of your speakers) needs repairs, you may find yourself packing your entire home theater back up – speakers, receiver, DVD player and all – just to obtain service.
      Last, but not least, having a brand preference may be able to help you guide your purchase.  After all, if everything else in your home is one brand, it might make sense to start by looking at the home theater systems offered by that same company.  Many manufacturers even offer features that enable several devices of theirs to be operated simultaneously using your TV remote, as long as they are connected using HDMI cables.
      While I can’t make any specific brand recommendations myself, one of the other forum users may be able to give you some feedback regarding a model that they purchased.

  • MacBook Pro vs MacBook Pro retina ???

    Hello peeps. I'm just trying to get some feedback. I can't decide what model I should get. I'm debating on getting the 13" MacBook Pro but idk if I should get the retina display one. I'm a college student so I will be using the laptop for online homework, research and ect. I will also be using it to edit pics and making family  videos. I also love music so I might have a lot of music in it as well. So please i would really appreciate it if I could get some feedback regarding what model would be best for me. 

    Welcome to Apple Support Communities. We're users here and don't speak for "Apple Inc."
    In addition to the retina MacBook Pro (rMBP), and the MacBook Pro (MBP), there's also the MacBook Air (MBA) to consider.
    http://www.apple.com/macbook-pro/specs/
    https://www.apple.com/macbook-air/specs.html
    http://www.apple.com/macbook-pro/specs-retina/
    You will have to decide your priorities, then rank them. Here's a short (but by no means comprehensive list):
    Cost
    Minimum acceptable battery life
    Weight/portability
    Screen size and screen resolution required by the apps you run.
    Minimum acceptable performance
    Built-in CD/DVD drive (or add an external CD/DVD drive for $79)
    Can RAM and internal hard drive/SSD be replaced or upgraded later by the user, an authorized Apple service facility, or not-at-all?
    College 'help desk' support for your choice of computer. It's great to be a trendsetter in some things, but you don't want to be "the only one on campus" who uses whatever computer you choose.
    If you walk to class and take your computer in your backpack every day, lighter weight and longer battery life could outweigh future upgradability and cost.
    The current MacBook Pro (MBP) 13" was introduced in 2012, so it is the oldest design and offers the shortest battery life, up to 7 hours. It includes a built-in CD/DVD drive and at 4.5 lbs, weighs about 1 pound more than the current retina MacBook Pro 13" (rMBP) at 3.5 lbs, and 1.5.b more than the MBA at 3 pounds.
    If importing music from CD's, watching movies on DVD, or burning CD's or DVD's is quite important to you, that benefit might outweigh carrying an extra pound or so around in your backpack, if an when you take your Mac to class or to the library. An external Apple CD/DVD burner is available for the rMBP and the MBA for $79.
    The 13" MBP has a 1280 x 800 screen resolution.
    The 13" rMBP has a 2560x1600 screen resolution, great for photo editing, but many apps use an apparent 1280x800 screen resolution.
    The 13" MBA has a 1440x900 screen resolution.
    The MBP comes standard with 4GB RAM or 8GB RAM, and IS user-upgradable to as much as 16GB RAM later.
    The rMBP comes standard with 4GB RAM, 8GB, or 16GB and is NOT designed to be user upgradable, I'd recommend that you purchase at least 8GB RAM for best performance with current and future operating systems and programs that use them.
    The MBA comes standard with 4GB RAM or an optional 8GB and IS NOT upgradable at all.
    The MBP comes standard with a 500GB traditional internal rotating hard drive. It is also available with a 1TB internal rotating hard drive, or with flash memory drive options of 128GB, 256GB or 512GB.
    The MBP internal hard drive or flash drive IS designed to be user-upgradable.
    The rMBP comes standard with 128GB of flash storage, available with 256GB, 512GB, or 1TB, and the internal storage is NOT designed to be user upgradable.
    The MBA comes standard with either 128GB or 256GB of flash storage, and the internal storage is NOT designed to be upgradable at all.
    If you select either the rMBP or the MBA, I'd recommend that you purchase at least 8GB of RAM installed, and a 256GB internal flash drive, because neither RAM nor internal storage can be upgraded by you later.
    In deciding how much to spend, I STRONGLY RECOMMEND that your purchase budget includes:
    1) a sturdy backpack or carrying case with a shoulder strap
    2) an external hard drive of at least 1TB or more for Time Machine backups, and
    3) perhaps a smaller 500GB second external drive if you have an extensive collection of music, photos, and movies that don't need to be occupying valuable internal SSD space.
    Stuff happens. Computers do stop working. In my opinion, the MacBook Pro, while an older design, slightly slower, and slightly heavier design, is less expensive, BUT is still a logical choice for many college students. It offers the advantage of you, the user, being able to easily upgrade RAM and internal hard disk (or flash drive) storage, when components fail or your needs change.
    Most college students (and their parents) qualify for a modest Apple Education Store discount and perhaps Apple financing for the purchase of a computer.
    Check to see if your college has a site-licensing program with major software vendors such as Microsoft and Adobe. If so, you can save hundreds or even thousands of dollars on software purchased for your use during your college years.
    If you are on a really tight budget (what college student isn't?), also consider purchasing a refurbished Mac directly from Apple. They are indistinguishable from a brand new computer, and often cost 12% to 25% less than a brand new unit. The only difference is that they come shipped in a plain brown box instead of the 'pretty' white retail box. Slightly older refurbished Macs are often available direct from Apple at even greater discounts. http://store.apple.com/us/browse/home/specialdeals/mac
    Both my Macs (a mid-2007 MacBook, and a mid-2011 iMac) were purchased direct from Apple refurbished.
    If you have questions, feel free to post them in this thread. I'm not online every day, but I do look at the forums at least several times a week.

    Hi Simon,
    I don't think we're on the same page here...   I'm asking about the creation of a lens correction profile, not the matching and application of a lens correction profile.   I've been using exiftool to supplement necessary EXIF data (e.g. FocalLength, FNumber, FocalLengthin35mmFormat, SubjectDistance, FocalPlaneXResolution, FocalPlaneYResolution)  to my images before using them to generate a lens profile in ALPC.  Since I've started creating profiles, I've found a couple EXIF data tags that were missing.  When I add them to the images and re-generate the lens profile with that same image set, the distortion and vignette parameters change, which proves that they are used by ALPC.  I'm starting to wonder how many other ALPC input parameters (EXIF tags) I'm missing.  So... Assuming someone has a fully manual system and has to add ALL of the EXIF data that ALPC would need to mathematically calculate accurate distortion and vignette models, what  EXIF data would have to be added?
    Thanks!
    - Jason

  • Canon S90 raw - lens profile overcorrect distortion

    I was able to successfuly create profiles for all my Nikon gear, but Canon S90 is a completely different story. I tried all possible variations, focus distance, diferent charts, sizes, changing advanced settings and so on, but the result is always way overcorrected geometric distortion. It actually makes it worse then original. If I reduce correction to about 22% then it looks right. The same applies to available S90 profile on-line. Chromatic and vignetting models appear to be correct.
    Original image:
    Corrected image in Camera Raw:
    I can send you zip file with original raw if you like to test it in the lab.

    The S90 images are already auto-corrected for distortion based on metadata. Hence the raw images processed by CR/LR will have a similar shape to the JPEGs produced by the camera (e.g., if you shoot raw + JPEG).
    At present we do not support user-created lens profiles for the S90 for raw files. This is a known limitation of CR/LR that will be corrected.
    The same limitation applies to CR/LR with regards to Micro 4/3 cameras and the Panasonic LX3 / Leica DLUX4.

  • Camera question: Canon Optura 50

    Like others among you, I'm preparing to buy a camcorder to use with my Mac, either with iMovie or one of the Final Cut versions. I'm wondering if anyone has any experience with the Canon Optura 50. I consulted Consumer Reports, and found it to be the only model they tested that was a) tape based (a propos of a valuable pointer elsewhere in these discussions that only tape-based cameras will allow post-production editing), and b) have all four of the following features, which I desire: 1) A/V input, 2) external mic input (very important to me), 3) headphones output, and 4) firewire capability.
    Any feedback on this model (Canon Optura 50), or other suggestions/pointers? Thanks.

    Welcome to the forum.
    You don't say what program you'll be using nor what computer you have nor your mode of shooting nor your artistic goals - but here's some generic advice.
    1. Canon cameras are notorious for their weak implementation of firewire and timecode - two significant issues when working with Final Cut.
    2. Their implementation of the firewire protocol is non-standard. Be sure to use FIREWIRE BASIC (a reduced instruction set) as the device control protocol when working with them.
    3. Canons don't play well with other devices on the same bus. Since all firewire ports on a Mac connect to the same bus, if you are using an external hard drive, you may need to install a firewire card (PCI, PCMCIA or Expresscard34 depending on your machine) to create a second bus for the camera. This isolates the camera from the hard drives. Once this happens, they may work flawlessly. If you have a computer model that lacks the capability of adding a second firewire bus, you could be SOL
    4. Some Canon cameras have never had an issue connecting and capturing. Some have major issues. In fairness to the brand, other cameras have connection issues as well but not to the same extent (as it would seem from the posts on these boards).
    5. Inexpensive cameras have inexpensive tape drive systems that will cost nearly as much as the camera to fix if they blow up. These cameras do not like the hammering of jog and shuttling when used as capture device.
    Good luck,

  • Since last update I get loud sound as atv is turning on?

    Since last Apple TV2 update I get a loud sound over the speakers for about 15 seconds when atv2 is initially turning on.  After the sound everything works OK.  Tried changing HDMI cables and HDMI port but problem remains.  This only started right after the update was completed.

    Sounds like an HDMI negotiation glitch in the current software.
    There is an audio setting on AppleTV for sound bit depth (8 bit or 12 bit I think - try both).
    If you've restarted AppleTV after unplugging and this persists, then I would personally restore AppleTV2 via iTunes:

  • EFI Firmware Update 1.5

    When I try to install the new update, it says that my computer does not need the update, but my BOOT ROM version is not the most updated version as listed on the updates page for the 15inch, 2.4 Ghz MBP. http://support.apple.com/kb/HT1237.
    Here is my BOOT ROM version in system profiler: MBP31.0070.B05
    My SMC is: 1.16f10
    (the update page says that I should have MBP31.0070.B07 (EFI 1.5))
    any suggestions?

    dagd wrote:
    The firmware in the BOOT ROM can only be updated a limited number of times. Therefore it makes sense to avoid firmware updates there is no need for.
    This is actually not true A flash chip such as the one containing the EFI ROM can be updated many times.
    Apple tests current hardware on a regular basis and examines user feedback on these models. If hardware problems are found in firmware, then Apple will issue an update, just like every other computer maker out there. The general wisdom of "if it ain't broke, don't fix it" comes into play; if you are not experiencing trouble, then pass on the update.
    Apple does not deliver updates that do not apply to a given machine or a given situation Last week's update for MacBook Pros was found only to be needed for two classes of machines:
    a) Second generation (Core 2 Duo 2.16/2.33), manufactured between October 2006 and May 2007, all models
    b) Third generation (Core 2 Duo 2.2/2.4/2.6 BTO) shipping with OS X 10.4.9 Tiger only, manufactured between May 2007 and October 2007
    Third-generation models manufactured on or after October 2007 and continuing through March 2008 contain build MBP31.88Z.0070.B05.0709261143 or later of the EFI firmware.
    Apple engineers discovered faults in both classes, including those already updated by EFI Updates 1.3 and 1.4, which were found not to exist in any machine post-October 2007. This fact was never made plain in the firmware release notes, which led many to believe they required the update when they were, in fact, just fine. Fortunately, Apple put a comparison routine into the installer script that stopped the update from being applied to unaffected systems.
    Hope this clears things up,

  • RAM upgrade: 8GB or 16 GB? macbook 2GHz

    Hi people,
    I've seen similar questions to mine but the model is not exactly the same to mine. I have a macbook 2011 model that runs Snow Leopard, and the specifications are :
      Model Identifier:          MacBookPro8,2
      Processor Name:          Intel Core i7
      Processor Speed:          2 GHz
      Number of Processors:          1
      Total Number of Cores:          4
      L2 Cache (per Core):          256 KB
      L3 Cache:          6 MB
      Memory:          4 GB
      Boot ROM Version:          MBP81.0047.B27
      SMC Version (system):          1.69f4
    Ram is DDR3 1333.
    I would like to upgrade my RAM to improve its performance because I need to work on many programs simultaneously and the virtual machines that I run are not satisfactory. At a store that is collaborating with apple, they suggested that I should better upgrade up to 8GB because of the processor frequency (no more than 2GHz), but how can I confirm that ? Can I have an official answer by Apple? If Apple approves it I would rather buy 16GB ram. But if it doesn't fit, and need to change with 8GB afterwards, the store doesn't return the money difference to me.
    They also mentioned that Apple provides either Kesington or FCM. Now they provide only FCM. What is your opinion about this brand? What about Crucial or Geil for example? Would there be a problem?
    Please give me feedback !

    Your model supports:
    Maximum Memory
    16 GB (Actual) 8 GB (Apple)
    Memory Slots
    2 - 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM
    There is no official Apple answer on the forums. Apple is not here answering questions. We are users just like you. Good RAM sources are:
    OWC
    DataMem
    Crucial.com
    Just be sure you get RAM with the correct specs. Although your model has been shown able to run 16 GBs, this is not the official Apple spec which is 8 GBs. That means that for most models like yours 16 GBs will work, but there is no guarantee it will work in every Mac in your model class.
    If you will be running emulators, then allow at least 2 GBs of RAM per running VM plus 4 GBs  for OS X if you need to run more than a couple concurrent applications.

    shame as MS must have all the code to do the things we need anyway, it's just that the object model is deficient.
    It'd be useful if there were an Exchange category on MS Connect where we could submit our suggestions, but as far as I can see, there isn't one.
    So, where do the Exchange TA developers get to hear customer feedback?
