• T3i sync high speed with popup flash?

  When shooting outdoors with a light background, it would be nice to be able to use the flash pop-up as a fill light (to the shadows on a face, etc..). However, the shutter speed is set to 1/200 when the popup flash is in place, overexpose the scene. Is there a reason why the pop-up flash can't sync high speed like an external flash to allow a faster shutter speed and always get a filling?

  Thank you

  It has to do with the amount of energy is available for the flash.  A more powerful flash can more easily manage the sync high speed.

  Sync and sync high speed are related to the work the Shutter curtain on any SLR digital.  There are two doors.  A slides open, and close other slides.  The reason for which there must be two doors (instead of one) is because that if there is only one, then the door would slide open, then reverses to slide.

  Assume the following scenario were true:

  Suppose it takes the shutter a full 1 second door to slide open.  If we set an exposure time of 2 seconds, the following should happen if there was only one door.

  -l' shutter starts to slide open from left to right, allowing light to reach the pixels on the left edge of the sensor.  The right edge is always in the dark.

  -as slides of doors, more and more pixels are eposed to light.

  -a second later reached the opposite end and all the pixels are exposed to light, but the door must immediately reverse and start close because it will take a full second to slide the door closed.

  -the door begins to move and immediately the pixels on the edge of most on the right are in the dark, because they are covered by the shutter, but the pixels on the left edge are still exposed to the light.

  -the door has finally reached the edge against a second later and no pixel is exposed to light.

  Think to what just happened... the pixels on the edge of 'left' of the sensor got a second exhibition 2... but the pixels on the right edge of the probe were barely exposed for a fraction of a second.  You'd have a horrible blow to look.

  To resolve this problem, the camera uses TWO doors... begins a sliding open... the other follows a moment later (based on the selected shutter speed) and starts sliding closed.  Now, all pixels are exposed for the same period of time, regardless of the shutter speed you use.

  But the reality is they are mechanically sliding doors and it takes time to move.  Flash sync speed is shortest possible exposure that can be turned where the first door has enough time to COMPLETELY slide open so that when the flash goes off, the entire sensor is exposed and benefit of lightning.  The second door can slide THEN closed.

  If you do not use flash and you set a very fast shutter speed (say 1/1000th) the second door actually starts closeing long before the end of the first door opening.  In fact the second door is "hunting" the first establishes a "slot" which sweeps the sensor.

  With this in mind... now think just what a flash how to predict sync high speed.

  Assume that your camera has a maximum speed of flash-sync of 1/200th, but you want to shoot at 1/400th.

  This means that the first door must begin to open.  When he reached the midpoint, the flash must trigger to light the subject - but half the sensor did not lightning.  The second door closes as the first door continues to open up.  When the first door reaches the opposite edge, the second door will now be in the middle.  The flash needs to fire AGAIN - this time to expose the pixels on the 2nd half of the sensor.

  This means that the flash should fire TWICE in quick succession and the impulses must be PRECISELY 1/800th second (half or your second 1/400th total exposure times) apartment.    No flash would be able to recycle in just 1/800th dry if she gave a burst of the power of the light.  In other words, that it must reserve at least half of its power for the second round.

  If you increase the shutter speed to 1/800th... now the flash to trigger FOUR times and no single burst may be stronger than 25% of the power of lightning - and gusts must precisely timed occurs 1/1600e seconds, independently of the other.

  You can quickly see how this is going to require a flash with a power or you won't be able to finish the sync high speed on something more than just a few feet.

  For the light of day, the most brilliant exhibition is going to be the sunny 16 rule... f/16 with the shutter speed, the value in contrast to ISO.  So, for 100 ISO, you can use 1/100th sec.  To f/8, you can use 1/200th (and now you are still below the max flash sync speed).

• PhotoSmart D110 with all different types of problems.

  We had this printer for a little over a year, and all of a sudden when you turn it on, you get different messages.  A saying you real ink is installed, the other saying print alighment page and briefly, he threw an error message, but it happened so fast I only had part, A 09, 37.  From there, it went to a screen LED flashing with all the lights flash continuously.  Now, when he arrives, he says incompatible print cartridges installed, which is not the case.  Here, I would give the whole error code, but I can't seem to get back to the top.  Any thoughts, or this printer is very likely over?

• How to avoid the stalemate between count with all and several calls from an EP getBackingMapEntry...

  We have a processor input, which initiates a transaction lite by calling getBackingMapEntry on several similar entries.  The same cache distributed these similar entries of accommodation also simultaneously services count with all call and we often a blocking scenario comes from the fact that the count with all call trying to access/key in the same cache block - but in a different sequence - date entry processor accessed (for example, the European Parliament access to similar input 1 then similar input 2 while the count with all attempts to block the same but entries in sequence 2) then the entry 1).  The obvious solution is to change the sequence entry processor accesses these entries to match the sequence used by the count with all operation, but we do not know what sequence consistency applies to operations NamedCache.getAll.  Anyone know?  We believe that we excluded (e.g., consistency does not consider wrt the count with all access sequence) the following:

  • The sequence in an ordered collection of keys such as a list that is passed as an argument to count with all operation
  • The hash code of the key value
  • Any use of Comparable on the keys

  We use 3.7.1 consistency where it varies between 3.7.1 and 12 c.

  Thanks in advance.

  We've thought of it (always happens shortly after the publication on a support site).  If anyone is curious, it seems that the binary class implements Comparable and that consistency sorts instance converted by binary key and access the Scriptures based on this order sorted.  If the entry processor converts the keys to binary instances, sorts and accessed in sorted order, there is no potential blocking (of our observations, at least).  It would be nice if Oracle should document this that people better understand how to write safe concurrent code.

• Problems with Adobe Reader and Flash Player

  I have IE 9 on Vista SP 2 that I was using the latest versions of Adobe Reader X (10.1.8) and 64-bit Flash Player.  When I try to open a file off of websites, I get a message that I need to download Adobe Reader or Adobe Flash Player.  I checked using the tools from the Adobe site, and both are installed correctly.  I can also open Adobe Reader and Flash files that I have stored on the computer.  It is a new problem on the two Adobe products in the past week.  Ironically, I have four computers with four different versions of operating system and IE.  10 IE with Windows 7 is also not identification Reader or Flash.  I also ran scans of complete system with Norton 360 and Power Eraser and found no problem.  I can't find a solution to these problems and the Adobe site has 'High Volume' so I don't know if I could even get help through Adobe directly.  It is the first time ever I have had problems with any Adobe application and use the Internet for literally his first days.  Any help would be appreciated.  I can be reached at [email address removed] although I can be gone for an hour later today.  Thanks in advance.

• Is it possible to create an animated gif with a different hotspot/link on each State?

  Hello! I was unable to find the answer to my question by searching, sorry if this has been discussed already.

  I'm doing a gif animated which is actually a small slideshow with a different link on each slide (or State, as are called Fireworks). But it doesn't seem to let me use a hotspot for all this, even if I insert in the layer instead of in the State. I tried to use slices instead of hot spots, and it does the same thing.

  Is this possible?

  No, you can not do this. It is not a question of fireworks, just the way work GIF animation. You will need to use Flash or Flash Catalyst for this type of functionality.

• How to make purchases in the apps I bought with a different ID to Apple?

  Here's the scenario:

  So Minecraft EP finally added texture packs, for the new Minecraft PE 15.0

  The only problem is, it costs money.

  Now, I'm happy to pay, but every time I try to pay it tells me "this application has been purchased with a different ID of Apple."

  I have three questions, if you meet one of them, the other those who do not need to answer. Reason by answering one of them answers the question, eliminating the need for my other questions.

  This is what must be answered:

  1: How can I pay for a purchase in an application, without using the Apple ID, I used to download?

  2. how to remove and reinstall Minecraft, without deleting its contents? (Worlds)

  3. How do I send money to another Apple? ID

  To justify:

  The second is more a question I should ask on the kingdoms of Minecraft, but you that someone here might know.

  Also, I have access to the Apple ID, but I'm not going to pay more money.

  I have money on the Apple ID iTunes, I want to send money money credit card.

  I would look into family sharing between more 2 appleID implement family sharing - Apple Support

  unless minecraft block shares then delete it and download it free for the other appleID and buy your dlc

• Hai, my ipod shuffle when it is connected with the computer, it flashes organge light.  If I don't take no light

  Hai, my ipod shuffle when it is connected with the computer, it flashes orange light.  If I remove without light and music.  Even I kept connected all day with my laptop for charging.  But without success.  Is it possible to change the battery?

  If the shuffle still appears in iTunes when you connect, you can try to do a restore using iTunes, where the cause is a software problem.

  Use iTunes on your Mac or PC to restore your iPhone, iPad or iPod settings - Apple Support

  If the problem reoccurs after the restoration, it's probably a battery worn.  Need soldering skills to replace yourself, and iPod shuffle (with the exception of the 1st generation) is very small.  Not easy to work on.  This web site has repair guides

  https://www.iFixit.com/device/iPod_Shuffle

  and parts are available from sources like eBay.

  Apple 'serve' the shuffle, if it's the 4th gen (current type).  Rather than change the battery of your device, you get a replacement unit.  According to this document, out-of-warranty fees are $39

  Pricing of the Service - The Apple iPod Support

  NOTE: If your shuffle is less than one year of the date of purchase, it is under warranty.

  The retail price of a brand new 4th gen iPod shuffle, with new headphones, docking cable and warranty of one year is $ 49.

• Using a counter with FiniteSamps and one with ContSamps

  I am using 2 counters on the NI USB-6229 (or USB-6259), case where a counter is implemented for FiniteSamps and another for ContSamps. I have the following MeasurementStudio code:

  ErrChk DAQmxCreateCOPulseChanTicks(hCnt0, "Dev1/ctr0", "", "20MHzTimebase", DAQmx_Val_Low, 0, 400, 400);
  ErrChk DAQmxCfgImplicitTiming(hCnt0, DAQmx_Val_FiniteSamps, 100);

  ErrChk DAQmxStartTask (hCnt0);

  ErrChk DAQmxCreateCOPulseChanTicks(hCnt1, "Dev1/ctr1", "", "20MHzTimebase", DAQmx_Val_Low, 0, 400, 400);

  ErrChk DAQmxCfgImplicitTiming(hCnt1, DAQmx_Val_ContSamps, 2);

  ErrChk DAQmxStartTask (hCnt1);

  When I run it, I get an error-50103 "the resource specified is reserved". If I change the FiniteSamps to ContSamps on the first counter, everything works fine.

  If I use only one counter with FiniteSamps, everything works very well.

  Is this a bug in DAQmx or the use of double counter on M Series devices is limited to ContSamps?

  VIC

  Hey Vic,

  It is actually planned on a device of the M series.  Here's a time diagram of the M Series user manual which might make this a little clearer:

  

  The device uses actually one counter for the other door so the result is a generation of finite pulse.  If you can provide the door from another source, you can configure a generation of continuous pulses on two counters and their door (DAQmx calls it a "relaxing break") of this external signal.

  You can also look at the use of the digital I/o correlated to generate impulses over multiple (up to 32 lines on your 6229 and 6259).  You could use one of the counters to generate a time base for digital lines and build the waveform as a result.

  One thing to note is that our new X series cards can generate a generation of impulses finished on a "single" counter (it was actually a paired internal counter that allows this).  There are four accessible counters by the user on the X series devices, which means you could generate four pulse trains finished.

  Best regards

  John

  In LabView, I found some examples but in C it is not seem to be any.

  Or you can add channels one by one with individual instructions: the follwing code compilation and runs without error on vitual DAQ hardware:

  ERR = DAQmxCreateTask ("", &taskH); ")
  
  ERR = DAQmxCreateAIVoltageChan (taskH, ' Dev1/ai0', 'AI0', DAQmx_Val_Cfg_Default,-5,0, 5.0, DAQmx_Val_Volts, "");
