• Close up lens for copied to digital slides

  I would use a Canon 500 d or 250 d close up lens with my 18-55 II or EFS EFS 55-250 II on a Rebel T3 to copy slides to digital.  Has anyone tried one of these combinations with success?

  I was paying too much attention to your question abou the 250 d and 500 d I missed the original topic - you want to scan slides.

  (a) a close-up filter is not appropriate.  Only a true '1:1 ' objective macro scale can do (for example the Macro USM lens EF-S 60mm f/2.8)

  but...

  (b) do not buy a goal for work of scanning... use a film scanner... a real film scanner.

  (c) consider all this sends to a service of analysis rather than yourself.  They are likely to have the best equipment and more experience.

• Webcam HP Pavilion DV6 has stopped working, it worked before, the message says webcam not started.

  The pre installed webcam works perfectly, but somehow, it works now so I;  I have re-insatalled Cyberlink software, but the webcam is not listed in devoce Manager, I get a message saying that the webcam is not started or is not found.  CyberLink Youcam software opens well, but the camera seems not to turn on. Is there a switch for the webcam harware? As there is a work around and turn off the WiFi? Perhaps a system configuration that controls what devices at boot time startup. It's as if the unit is just off, not activated, the close the lens light now, it used to.

  Your help will be very appreciated.  How can I activate my WebCam HP pre-installed?

  TIA

  It comes to my HP Pavilion dv6and the problem of my WebCam suddenly stopping.  I have posted two previous requests for assistance, does NOT see much in the way of answers.

  If I had held my breath waiting for some help or answers to this place - I'd be dead now days.  I tried everything I could think of; reinstalled the software, drivers.  But the error message was always the same saying that "the webcam was NOT turned on."  Back, through some other posts, that I could see that others have also had the same problem and all the guys from HP that mentions his HP job; has said was to reistall the software, or choose the webcam in the CyberLink WebCam software. but this option is still grayed out.

  So I just bit the bullet, because I had to do in the past.  I took off the inside of the plastic frame for the screen at the top and sides.  I had to unscrew two screws at the bottom of the screen frame to the hinges, under self-adhesive pads oval plastic/rubber.  In the Center, you can see the small Assembly of camera and microphone, with white wires, it will.  At that time, I had to put on a second pair of reading glasses, because the parts are so small.  I finally found a tiny multi wired plug-and - taken right of camera lens Center.  I loosened and then pushed with a small bamboo skewer.  When I buttoned up things up; and restarted the CyberLink WebCam driver program came to light on near the lens and the camera showed a live video image which aimed directly at me.  This plastic frame is very fragile and the two small screws will immediately far jump on the floor that you haven't cleaned vacuuming lately.  Has disappeared!

  I must say that I have had absolutely NO help from anyone at HP, I is uncomfortable taking my laptop apart to fix a poorly designed plug/plug obvious for the WebCam.  I like really this computer basically, perfect Beats Audio work for my deafness, I get more and more clear than any other volume laptop that I have tried over the past 20 years.

  I added Ram 16GBs of memory, but I have not noticed that much improvement, maybe when I make more digital video, CAD/CAM and photographics.

  I hope HP can get the image into the connector on the WebCam release and let us know how to fix it with a technology tech or something.  I tried searching and was NOT able to find the answers for my laptop either, I had the chance-out to allow him to run again, I hope you can get yours working again too.

  See you soon,.

• Gzip request to the web application server Java

  Hi experts,

  My first post here.

  I am building a Java for Blackberry application that needs to send data relatively large (in the hundreds of kb/s) on a web server.

  Since the mobile internet connection is not fast enough transfer a lot of data will take a lot of time.

  Question is, how can I compress data with gzip and handle it on my web server.

  Currently, I have

  String data = "a=b&c=d";
  OutputStream outputStream = httpConnection.openOutputStream();
  outputStream.write(data.getBytes());
  outputStream.flush();
  

  I'm guessing that blindly that I need to do something like

  GZIPOutputStream gzipOutputStream = (GZIPOutputStream) httpConnection.openOutputStream();
  gzipOutputStream.write(data.getBytes());
  gzipOutputStream.flush();
  

  Is this correct? Moreover, how should I handle it on my Web server?

  Would my server Web decompress this data automatically, so I can just get the values of the parameters a and c normally?

  Can I send different Content-Type?

  Please notify. Thanks in advance.

  As shown rcmaniac25, you must wrap the output stream you get from the connection inside a GZIPOutputStream new object. For any compression, however, you must also specify the compression level.

  As to whether the data will be decompressed on the side server depends on the server. At a minimum, you must set the content-encoding property for the connection before the display of the data. I highly recommend adjustment of the length of the content; to do this, write the data compressed in a buffer of bytes. I also suggest setting a user-agent header, because some servers incorrectly claims that come without one. Finally, I suggest you add a header x-rim-transcode-content with the value 'none' from the data is not intended for a browser. (The server must also affect this header in the response.) This is particularly important if through MDS or BIS.

  Put them all together, it might look like this:

  String data = "a=b&c=d";NoCopyByteArrayOutputStream bos = new NoCopyByteArrayOutputStream();GZIPOutputStream gos = new GZIPOutputStream(bos, GZIPOutputStream.COMPRESSION_BEST);gos.write(data.getBytes());gos.close();int len = bos.size();// unqualified constants below are available if your class// implements net.rim.device.api.io.http.HttpProtocolConstantshttpConnection.setRequestMethod(HTTP_METHOD_POST);httpConnection.setRequestProperty(HEADER_USER_AGENT, "MyUserAgent");httpConnection.setRequestProperty("x-rim-transcode-content", "none");httpConnection.setRequestProperty(HEADER_CONTENT_TYPE,    CONTENT_TYPE_APPLICATION_X_WWW_FORM_URLENCODED);httpConnection.setRequestProperty(HEADER_CONTENT_ENCODING, "gzip");httpConnection.setRequestProperty(HEADER_CONTENT_LENGTH,    Integer.toString(len));OutputStream os = httpConnection.openOutputStream();os.write(bos.getByteArray(), 0, len);os.close();
  

  If you post something in addition to the url-encoded name-value pairs, of course, you must use the appropriate content-type header value.

  I think (although I've never tried) that Apache will honour the content-encoding header on poles, condition mod_gzip is turned on (which it usually is). Most of the other web servers (Microsoft IIS, Sun Java Web Server, Nginx, etc) also support HTTP compression.

  I suggest you to test this with a simple script that simply takes your POST data. If it resonates as expected, you're good to go (but see below).

  If the server does not automatically unzip the application, then you will manage all script processed the MESSAGE. PHP, Perl, Ruby, etc. all are excellent tools to treat the gzip data. You'll just have to deal with parsing the url-encoded name-value pairs explicitly. But there are great tools in all these languages for that, too.

  Be aware that there may be limits to the amount of data that you can POST in a single application. You may need to consider dropping your messages in blocks of manageable data.

• Cisco TelePresence PrecisionHDMC USB camera

  Nice day!

  I have some problems with the usb camera: it is not a picture of the camera in Skype/vlc, violet only background. If I close glas lens, I see the banner with logo cisco and non-functional video icon. MIC is ok. Used OS Win7, Win 8.1, software for camera CC1.5.0/CC1.4.1 is installed, but only for Win7.

• What is a good lens to get to Montana

  I have a Canon T3i but you may want to rent a lens wide angle... I currently have 2 kit lens

  Do you take lots of pictures of wild animals?  Unless you are planning a trip with the express purpose of photographing wildlife, it is unlikely that you will capture the many wildlife shots by a big goal in your bag, just in case.  You're more likely to frighten the wild animals because they'll notice long until you spot them.

  The best wild shoots are carefully planned in advance, taking advantage of knowledge about particular wildlife you want to shoot.  For example, the construction of a blind near an area known for birds to gather, then occupying the blind before sunrise and stay inside of her for hours at a time.

  If you have a 70-300mm camera kit lens, you can be disappointed by the quality of the image when you take critical pictures, if you have not already visited.  With an APS - C camera, a focal length of 600mm would give you a lens equivalent 35mm to 960mm.  Without little practice, it will be difficult to capture sharp images in mothering the camera with a lens at this focal length.

  Long zoom can be expensive and cumbersome to wear.  They come with a learning curve, if you've never used one.  You would need to carry one to its ' own bag, or you would need a big backpack to carry it with the rest of your equipment.  Certainly, you would benefit to transport a fairly sturdy tripod, in order to support the weight of the super telephoto.  Outdoors, the wind can be a detrimental factor.  Wind can shake a light tripod, especially weighed down with a heavy load.

  If feel the need to perform a long zoom, I recommend one of the 70-200mm lenses and leave your zoom 70-300mm camera kit at home.  You can capture pictures of very good wildlife, casual without using a super telephoto.  Your APS - C body can transform a lens 70-200mm in 35mm equivalent of 112-320mm, which is close to the focal range of the Canon 100-400 mm zoom.

  One of the two Canon EF 70-200mm f / 4L lenses, with or without IS, might be a good choice.  I would put a priority to travel light and less so now in preparation for each scenario.  Don't forget, you can always crop a photo taken with a lens quality and always wind upward with a good result.

• I would like to replace a with an equivalent Canon Sigma lens.

  The lens is a Sigma 70-300mm 1:4-5. 6 DG with macro.  Which Canon lens would come close? The body is a T3i Rebal EOS.

  Thank you

  If you are serious about on the side of the fauna of it think the Canon 100-400 L IS lens, or even the Sigma 50-500 OS (kinda big & heavy for hand holding a large part) and read existing threads on the 100-400 & the 400 f5.6. It is a much better scope for wildlife that only 300 mm. You should also consider a good Macro lens for near work place that is not something I do, I'll let the others he made recommendations.

• a lens EF-S 55-250mm f/4-5. 6. IS STM will work on a powershot sx500?

  a lens EF-S 55-250mm f/4-5. 6. IS STM will work on a powershot sx500?

  Yes, it looks like one of my chipmonks lol

  You can see how it performs your depth of field considerably long distances. Youshouln can't still need in most cases with this power zoom. You might need a tripod unless your super stable.

  It is a generic TV converter I don't see any listed for your model, I have the similar to your SX50HS. I use adapters to mount a 2 X tele-converter that Ive had for a former model Powershot to mine, but only on close shots with zoom, very little.

  I found with 50 X zoom that I don't need.

• Lens EF - S v Lens EF - Crop Factor (factor of Conversion of Image)

  Good evening

  Please excuse me if this is a stupid question.

  If I use a lens EF-S on a camera with an APS - C sensor, the sensor capture is all that I see in the viewfinder, i, e, with a ratio of 1:1?

  In other words; the EF-S-objectives overcome the factor of Conversion of Image or Crop Factor happening with EF lenses on cameras with an APS - C sensor?

  The Crop Factor means that what you see in the viewfinder is more that actually he is captured by the sensor by a ratio of 1: 1. 6.

  I understand that the rear of the EF-S lens is more close to the mirror and, therefore the sensor, as the rear of the EF lens, which leads me to think that the image seen through the viewfinder with an EF-S lens is closer to that which will appear on the sensor than an EF lens.

  Thanks a lot for any response that confirms or refutes my guess, preferably with an explanation in simple terms.

  Joe.

  The ' in the name of EF - S stands for short focal length. This is of no interest to the user.  And the crop factor is also of no interest to the user.  The camera crops nothing.  It is a full frame in the sense you get what you see in the viewfinder.

  The term arises because of old film camera using 35 mm film.  Someone wanted to know how to compare the two.

  People do not really consider it iphones as crop cameras but they are.  As a Canon Rebel is.  Nobody calls a medium unit format and the camera of enlargement.  But it would be if you used the same logic.  Forget it.

  It is best to think in terms of "point of view" (AOV).  That never changes no matter what device you use.  For example...  Any lens that give a degree 46 AOV is considered to be normal.  It makes no difference what device you use.  This specification is included with each goal.  MM tells you what is the objective.  AOV tells you what it does.

• Best first lens for macro photography wide angle

  I am looking for more information on using lenses wide angle and tube extension to close to the top of the photograph.  The images will be used to capture the surface contours using PhotoModeler software.  This requires the use of a first goal.  I bought a 60mm Canon macro lens, but focal length is a bit long and surface data contain a lot of noise because the light rays are nearly parallel.  The target area containing reference marks, who must fill the area of the image of my 7 d is about 1.5 "square and the topics, located in the Center, are usually smaller than 0.75".  I'm looking for the 20 mm gun (or a 24 mm lens) for use with extension tubes.  Someone with experience with these lenses in close-up photography?  If so, what depth of field could hope for.

  I will propose a tilt shift lens and series II Canon 24 mm or one attachment bellows with a lens in the 35mm range.

• Lens EF-s 50mm f/1.8 VTS good for a woman "point and shoot"?

  As my title, my wife is a photographer 'point and shoot '.  It uses mainly its point and shoot at the school where she teaches to take portrait photos and the occasional action shot of his students (Pre-school-age, inside and outside).  The EF-s 50mm f/1.8 VTS goal would be a good 'all around' lens for these types of shots?  I have a rebel T6i I bought because some of the more advanced features (variable lens and manual control) to a DSLR wanted on a point and shoot and the ease of use for my wife.  I also wanted the WiFi features as my wife has no idea what a SD card is (it is very technically challenged) and I wanted an easy way for her to transfer his punches to his iPad (which the T6i has accomplished admirably).

  Thank you

  John

  "Not very good for free kicks or a groups because of the depth of field with the fixed focal length but can be artistic."

  It's a little... ah... bad!  Top of the list when is to compare a target of 50 mm zoom, a prime number is more limited to what he does well.  This means that you need to weigh the bennys for inconvenience.

  A 50mm on a T6 can be great for the quick because you do not have to be as close to the child (s).  It may be a problem because you can not be closer to the child(ren).  Do you see this trend a bit. The 'deep-fo-field' DOF, has nothing to do with it in this case.

  No Point and shoot, P & S, who deserve to have confined to a fixed lens or privileged.  That is to say, the series G of Canon P & s.  I have a G15 and it ia a great camera.  However, this level of P & S is not at a great price.

  Sorry, but the lens I would recommend for her and you won't come cheaply or the other.  But you already dropped the piece on a great device so here is my thought, EF-S 17-55 f/2.8 IS USM.  It almost gives you the best of both worlds.  It's fast.  It has a good range of focal lengths.  It has a remarkable IQ.  It will be the T6 as close to the best P & S there.

  So my answer to long-term to your question, ' EF-s 50mm f/1.8 VTS good for a woman "point and shoot"?

  No, it wouldn't.

• Please recommend lens for portraits

  Hello.

  I am totally new to photography.

  Bought Canon 600 d with 18-135 lens. But he has [email protected] the lowest.

  Please suggest a lens for portraits

  Maximum extended budget $600 If she made a significant difference to a photographer very amateur like me.

  The Canon 50 mm f 1.4 objective is probably what you are looking for. On a crop body, it behaves like a 80 mm with a shallow depth of field (DOF) lens when shooting wide open or close expansion Xtreme
