    HDRbox Tone keeps popping up, like it is supposed to

    M5 Studio+Design

      I recently updated to CS5. I convert my Jpeg of raw images to 32 bit while editing. I then save as and covert back to 8 bit jpeg for uploadsing to MPix or my website. This is how I have used my previous version of photoshop. Now in CS5 a HDR Tone box aoutomatically appears before converting to 8 bit. I can not turn it off and therfore can not convert from 32 bit tiff to 8 bit jpeg. How do I convert back to 8 bit jpeg without this stupid box appearing?

       

      Thanks

          THe HDR toning options always come up when you convert 32 bit/channel to 8 or 16 bit/channel - that hasn't changed.

           

          But the big question is: why are you editing your 8 bit/channel images in 32 bit/channel HDR mode?  It seems like you might be using the 32 bit/channel mode by mistake.

            I am not using HDR mode. HDR Tone box appears when I attemp to convert from 32 bit tiff to 8 bit jpeg.

              You are using HDR - that's what 32 bit/channel mode is.

              Again, it sounds like you're using 32 bit/channel by mistake.

                The box is supposed to pop up.  It is not "stupid", it offers you choices you need to make.  Chris is implying that whatever you did before that left you with a 32 bits/channel file you need to "convert to 8 bit jpeg" may have been a choice made on wrong assumptions.

                 

                When the HDR Toning dialog comes up, just select the "Exposure and Gamma" method, leave the controls alone, and click [ OK ].  That will give you the conversion you expect, I imagine.

                  If a dialogue box pops up for a editing method you did not select and

                  forces one to use it what would you call it smart? My choice is to not use

                  it and close but that is not a choice given me. I have been converting to

                  32 bit, editing, doing a save as 8 bit for 300 dpi. I convert to 8 bit for

                  web and print. I then save the 32 bit version as a edited master file. I

                  have been using this method successfully purposely in photoshop 5.5 for 10

                  years so no "assumptions" have been made. During this time not once did an

                  HDR Tone box pop up and prevent me from finishing my conversion to save as

                  8 bit 300 dpi. If you used 5.5 then you know the distinction from CS5. I

                  recently changed to CS5 so I have no idea what an HDR Tone box is.

                  Hopefully my frustration with HDR being crammed down my throat will be

                  better understood.

                    New software gets new features.

                     

                    What is your reason for using 32 bit editing?  What can't you do in 16 bits/channel, which is where folks not doing HDR generally work?

                     

                    Is it possible you've convinced yourself that for some reason you need 32 bit floating point format, but you really can't justify why?  I don't mean to be critical but I get the impression you're not really doing what you think you're doing.

                     

                    It's been many years since I used Photoshop 5.5...  I don't believe Photoshop 5.5 even gave you the ability to use 32 bits/channel.  It's not available in Photoshop 6.0 (I have a copy of that installed here).

                      The reason I convert to 32 bit is to have the best quality image for

                      editing. When I took photoshop in 1999 this is the method I was taught to

                      create the best file quality. save as 8 bit and keep the 32 bit as a edited

                      master file + the original unedited. I don't shoot HDR. If 32 bit is HDR

                      then perhaps I forgot after 30 years of photography. I have in the past

                      combined 2 negatives of the same scene to create a better tonal range in my

                      image, B+W of course. Of all imaging tasks, image editing demands the

                      highest dynamic range.

                        I'll let Chris comment, but I can see no benefit to converting a single 8 or 16-bit image to 32-bits. There may be some benefit (though not a ton) to converting an 8-bit image to 16-bit.

                         

                        If you're combining brackets of images into 32-bit files, then you do need to go through the HDR toning dialog so Photoshop knows how to map the 32-bit data to a 16-bit representation. Otherwise, you're just throwing away data randomly.

                          You did select 32 bit / channel / HDR mode, and then you got a toning dialog when you tried to convert out of that mode - exactly like it is supposed to work.

                           

                          As long as Photoshop has had 32 bit/channel floating point HDR mode, you have gotten a toning dialog when you convert down to 8/16 bit modes.  That has not changed.  I'm pretty sure of that, since I wrote all of the code involved.

                           

                          Again, it seems like you are using 32 bit High Dynamic Range floating point mode to edit your 8 bit (Low Dynamic Range) integer images by mistake.

                            In 1999, Photoshop didn't have a 32 bit/channel HDR image mode.  You could only go up to 16 bit/channel.

                            32 bit/channel was added in Photoshop CS2, released in 2005.

                             

                            No, not all image editing demands the highest dynamic range, especially when you don't understand the capabilities and limitations of the highest dynamic range mode.

                              I think the point of having greater bit depth for editing is that each time

                              you do something to the image, the result has to be quantized to the bit

                              depth you're working in. I felt that you have more info for editing and

                              thus more info get's transferred when making the 8 bit depth file.

                               

                              My memory of that class was the instructor telling the class to edit at the

                              highest bit mode. But I do recall that 16 bit was the max when I had 5.5 so

                              my bad.

                              The version I edited with in 32 bit was CS 2 and I don't think I was

                              converting to 32 bit by mistake for 7 years. The HDR Tone box did not

                              appear in CS 2. My image would convert to 8 bit without issue.

                               

                              My question was why does CS 5 have this HDR box when CS 2 did not and how

                              do I bypass it. I will call adobe to ask why this type of editing was

                              possible in CS2  but not CS5

                                No need to call. Chris is the authority. He wrote the application.

                                  With CS2 I had no problems with HDR box appearing when converting from 8

                                  bit to 32 bit and back to 8 bit.  It doubt it existed in CS2. Now I have

                                  CS5. The HDR Toning dialog appears automatically if I switch from 32

                                  Bits/Channel mode to a lower bit depth. The result is my edited image that

                                  was carefully edited suddenly has colors that become garishly exaggerated.

                                  My only choice I am given is to begin editing again using the controls in

                                  HDR box. I just want to save and close as I did in CS2, not be forced to

                                  edit my image again as a condition before I close my file.

                                      Yes, the HDR toning dialog existed in CS2, and showed whenever you converted from 32 bit/channel to 8 or 16 bit/channel.

                                       

                                      As Noel already pointed out, you can use the exposure and gamma tonining operator to preserve the on-screen appearance of your 32 bit/channel image.

                                       

                                      And, again, you are making a mistake in using 32 bit/channel in the first place.
