• How accidentally convert all my images to 8 bits?

  Hello

  Five minutes ago, I checked my image in Camera Raw before import into Adobe Photoshop CS6 wasn't in 16-bit mode.

  Immediately after that I imported into Photoshop and it became a document .psd, I checked once more that he was always in 16-bit mode.

  Then I created a duplicate layer, selected the sky and created a mask layer from this selection.

  Not much.

  NOW I SEE from below, I am in 8-bit mode.

  Why is this?

  It is true that ANY MASK I create forces the entire image in 8-bit mode?

  Thank you!

  

  The documents should never spontaneously of course change the bit depth.

  Opening a Camera Raw image in Photoshop, the title of the document should not end in '.psd' until a backup (in PSD format). Have you made the steps other than the ones you have described?

  Your thread title says "all my images. Do you mean that you have had many 16 - bit documents open in Photoshop and all except one of the inactive tab in your screenshot became mysteriously 8-bit?

  Look in the history panel after a doc past from 16 bits to 8 bits. There is an element named "8-bit/channel"?

• How to convert the Bitmap Image in BlackBerry

  Hello

  In my application, I get the picture from the server. Now, I want to convert this Bitmap Image to display on the screen. For this I use below codes. But it doesn't give me the same image does not mean with the clarity and the exact size. He's smaller than the picture.

  I used the codes below:

              Logger.out(TAG, "It is inside the the image conversion        " +img);
              Image image = Image.createImage(img);
              byte[] data = BMPGenerator.encodeBMP(image);
              Logger.out(TAG, "It is inside the the image conversion---333333333"+data);
              bmp = Bitmap.createBitmapFromBytes(data, 0, data.length, 1);

  Why you want to use a bmp image?
  You can just use png, jpg or whatever of the original image is.

• How to convert a processed image back to its FIRST original

  I work with designers who want to see a DNG converted, edited, but then they go back to the original RAW and re - crop, change the balance of the colors etc according to the work to be done. How can they do that in Photoshop?

  Thank you!

  I'm not sure that's what you have in mind, but if you want to clear your RAW settings, you can do from the bridge by choosing the image and the settings by choosing Erase as stated above.

• How to convert a Tiff image to JPEG without being FORCED to 8-bit color?

  I'm an artist.  I have high quality TIFF images.  When I convert TIFF to jpeg it make me color 8-bit automatically. (Forget about 32 bit - it does not in jpeg format that at all)   The only way that I can return to the 16-bit color is to use the already broken file and bring it up to 16 bits.  IT makes NO sense at all.  Once the jpeg format is broken, how is the world supposed to convert back to the top. ??  So even though it says that you have converted the 16 - bit file, metadata is always about the 8-bit file.

  In addition to en plus de tout all this confusion, an image, for example, in the case of so-called converted to 16-bit, gets a lot grow so even the original Tiff image.  It looks good on the one hand and more exposed on the other.  I guess that's throwing in resolution photoshop fake, I'm good?

  I'm wasting my time with this 16-bit imaginary conversion?

  Is it possible to take the original Tiff image and convert default 8-bit to 16-bit jpeg without value?  I tried all sorts of things.  I even asked my web guy.  My web guy said only 8 bits is unexceptable for printing, same for the web.

  Would this have something to do with my computer and the scanner?

  I have the memory of 8 GB iMAC OS X 10.8.3 (3.2 GHz).

  And I also have a capable graphic arts Epson Expression 10000XL scanner from scanniing to 48-bit color.

  This color stuff is really important!  This is IMPORTANT!  I have files FINE art.  I'm already losing so much quality with jpeg conversion. (which I am required to do for SmugMug, in addition to the compression of all my files of 50 MB or less)

  Anyone who knows anything that could help me would be much appreciated.

  Aloha,

  -Melissa

  First jpeg is 8-bit only it there's no way to register as a 16 or 32-bit jpg, just does not exist. Secondly people print in 8 bit all the time and most if not all web graphics are 8-bit because this is the only way to see because there is no 32-bit or 16-bit monitors to see. All pro monitors are 8-bit monitors.

  If you like on the color range and want the range of colors that provide 16 and 32 bit, so why jpg? Jpg by his own nature throws of color just to compress, why it is popular on the web, because of its small file size not its quality. If you need 16 or 32-bit for what it is, it must be in a format that supports this color depth.

  That being said, that a jpg to 8 bit image displays 16 million colors, 256 shades of red, 256 shades of green and 256 shades of blue.

  Now, here's where I think your information bit is disabled. a jpg image is a 24-bit image that will produce 8-bit red, 8-bit, 8 bits of blue and green.

  8, 16 and 32 channel are not total not the color information.

  If the overall picture was of 8 bits, the image would be gayscale.

• How to convert FLIR gray Image to a map of temperature in NI VBAI

  I worked with an infrared camera FLIR A315 and software VBAI of NEITHER.  I need determine the presence and continuity of a hot mastic foam which has been injected into the hollow bulb of a bead attached to 4 adjacent places that flow together inside the bulb of weatherstripping to form a continuous rubber scoured the filler plug.

  So far, I was able to trigger image acquisition in VBAI from a FLIR infrared camera monitoring the status bit an Allen-Bradley PLC.   Communication with the camera FLIR A315 is via the IMAQdx GigE driver.  However, I did not understand how to determine the temperatures of the gray scale images I get from the FLIR camera.  I wonder if someone could give me some advice on how to do it.

  I have attached a few images below to illustrate what I work with and to what extent I'm away.

  • iPhone_Photo.jpg - shows a photograph of the stripping section that the FLIR infrared camera is 'looking '.
  • FLIR_IR_Monitor.jpg - a screenshot of a FLIR Infrared Monitor utility that shows the temperatures measured at a number of points and areas (showing that it is possible)
  • NI_VBAI.jpg - part of my VBAI 2010 project that shows the image, I have acquired the FLIR A315 IR camera

  So, I am part of the path, but so far have not found a way to map the image of gray-scale that VBAI acquires the infrared camera FLIR in a heat map where I can determine the temperatures - and would be grateful for the help on how to do it.

  Kind regards

  Nick

  Hello

  Image provided by the FLIR camera are unsigned 16-bit.

  According to the temperature scale FLIR selected (10mK or 100mK), you have to divide by a factor of 10 or 100 to get the values of K. Do not select Exit radiometric.

  If your object is cold, the population of the histogram of the image will be on the left side of it and if the object is hot, the population of the histogram will be on the right side.

  If you want that your values of temperature in degrees Celsius, just add 273.15 Kelvin value.

  Then you can add a color palette in VBAI (iron FLIR is available)

  Hope this helps

• How Photoshop converts the RGB 16-bit values to 15-bit and 8-bit?

  Can someone please help me understand what rounding of diet or another algorithm is used when Photoshop reduced a 16-bit color 8-bit?

  For example, the two colors (was and B) are the colours of 16-bit swatch taken directly from a file of the ACO:

  A16 = (61603, 60948, 58982)

  B16 = (58326, 57015, 52428)

  Photoshop displays the values of "16-bit" (acutally 15 bits) as well:

  A15 = (30802, 30474, 29491)

  B15 = (29163, 28508, 26214)

  It seems that the 15-bit values are the result of the division by two and rounded to the nearest integer.

  With 8-bit, it's another story although:

  A8 = (240, 237, 229)

  B8 = (222, 227, 204)

  Now, if we divide the 16-bit value by 256, the following:

  A8_float = (240.6, 238,1, 230,4)

  B8_float = (227,8, 222,7, 204.8)

  It's a similar story during the allocation of the 15 by 128 bit values. No system rounding or truncation will get the same answers as Photoshop for 8 bit I see. What I can't work, it's how Photoshop calculates these figures. It's the division of integers, floating point division with rounding or truncation? I'm puzzled. Help, please.

  -> range 32768-65535: (32768 * x + 32767) / 65535

  Not quite dividing by 2, otherwise you miss the white point.

  32768-> 255 range: (255 * x + 16384) / 32768

  With the exception of dithering, it is all simple mathematics.

• How to convert a number to a 10-bit array that will go in an external DAC (AD7533)

  Hello

  This here is my situation.  I'm using with LABVIEW to program a CPU in the following way:

  1 Laview calculates the values of a sine wave, according to the number of loop iteration. (i.e. generating a value of the sine at different frequencies).

  2. it is adjusted between-/ + 1.

  3. I connect an array of digital output ports to an external, independent, four quadrants, 10 - bit DAC. The part is AD7533, and I hope I can use it in bipolar configuration.

  My question is, how do I convert the number of sine wave (or triangal, sqr, etc.) in a table of values of T/F can I stream through my DAC and output a sine wave signal?

  I tried number Boolean array with the calculated value of sinus, but do not give me any bits of hard.

  All suggestions greatly apprec.

  RTom

  Post what you have done so far.  Are starting you with a a U16 or I16 whole bit (or more)?  How do you do the scaling between +/-1 and an integer.  It should be just a matter of using the table number of Boolean and then using a subset of the table to reduce up to 10 items boolean.  If you are starting with an integer I16, it may be a matter of taking the element of corresponding table of the sign bit and the 9 elements that correspond to the less significant bits, to put together to make an array of 10 elements.

• How to convert specific images on my Clipboard to text once paste the picture on my .pdf document?

  Hey Adobe experts, I could really use your help.

  I have some screenshots of school I pasted on OneNote. These screenshots have a large amount of text that I could use. I created a large .pDF document where I saved my notes and text. Now - how to convert the SPECIFIC images that I stick to the text document? I use the word 'Specific' here because I know I can run OCR on a blank page without any text. But how to do OCR on an image

  It automatically happened a couple of times when I tried to save the document immediately after I pasted the image - when I was under "Edit PDF" I was able to edit and change the fonts of the text. But how can I do this at will? Is there a special button somewhere?

  P.S. I already tried to OCR - but it's only limited to pages without already "renderable text".

  I use Adobe Acrobat Pro DC; 8.1 Windows machine

  Hi SinNombre,

  If you are referring to perform OCR on a page with the image and the renderable text, it is not supported. However, you can use the following workaround for the same thing:

  1. print the PDF document to Microsoft XPS Document Writer or accessing the file-> export to...-> Image-> (an example of TIFF or PNG format)

  2 convert the output created in PDF format. This PDF file contains all the texts and images in the form of images.

  3. run the OCR on this PDF.

  This should solve your problem

• How to convert RGB to CMYK images in batches

  Hello

  Can someone explain in a way step by step how to convert RGB to CMYK images batch?

  Thanks in advance

  If you do not want to use Photoshop for the conversion of bact there are several ways, including lots and Image Procesor under the file > controller or file > Scripts of PS.

  However, my preference is to use the script from Russell Brown: Image Processor Pro, via the bridge:

  http://www.russellbrown.com/scripts.html

  Like other similar is transformative image:

  http://www.scriptsrus.TalkTalk.NET/

  Both allow you to make several conversions simultaneously, different sizes and file types and actions running before or after conversion.
