The only way I can see at present that js1138 was being truthful when he said the only parameter he changed is the angle, is the possibility that he might have a different version of Photoshop, and that the respective versions might have different controls for the offset. That might sound farfetched, but since I don't have Photoshop, it would be helpful to see a screenshot of Swordmakers's version of Photoshop version and of js1138's version of Photoshop.
Cordially,
Did you notice I asked for that EXPLICITLY in my post #255 this thread, before the pissing match started?
Tell you what. Give us the image in #252, and a link to the original image you fed into photoshop to get that image, and the version of photoshop you used. Then tell us the exact angle you fed in, and let other people try using all that information and the original photo, if they can produce the image you did in #252.
Science is about reproducibility under controlled conditions, right?
In #268 js1138 wrote the following:
When I was asked for the settings I used I posted them. You persist in using settings that I did not use.
(SNIP)
But js1138 did NOT post all of his settings: the dispute is that the original picture of the Shroud in 252 which js1138 gave, Swordmaker could not duplicate without fiddling with the OFFSET, which js1138 did not mention the use of, or give a value for.
In Posts #262, #264, #267, Swordmaker uses the offset and the angle, and clearly identifies each and gives the resultant picture, for The Shroud, for Obama, and for the X-Ray. In each case he shows that the blurring (present in js1138's Shroud picture) can be created by using the offset value.
But js1138 left off the offset value in his post #252 - and then has the nerve to accuse Swordmaker of confusing the isssue:
Now to prevent you from making a complete idiot of yourself in public, try this: take an image such as the x-ray, find settings that give a reasonable 3D effect, and then vary only the angle.
Swordmaker finally has to show that for a fixed offset, you NEVER get the effect js1138 claimed came from angle only. He shows you only get the effect by playing with the offset.
He then goes on to misquote me or to lie about what I asked:
Now, I have done what grey whiskers asked me to do. I published a series of images showing the effect of varying the angle.
I called him out on this as an explicit misstatement, or lie, in post #270.
Can each of you tell us the version of Photoshop, and the version of the OS you are running on?
js1138, why don't YOU go first, since I had asked you a long time ago, and it is your credibility which is in question: Swordmaker has been more forthcoming, and less prone to try to change the subject or obfuscate, throughout this thread.
Cheers!
You asked me to post my settings and I posted the exact settings. They are truthful.
Now, in the interest of the whole truth, I will discuss Swordmaker's comments. He has some valid things to say, but he is completely off base in saying I am dishonest.
First, his valid comments: He says my offset is too high on the shroud picture. He is correct that the offset is higher than anything you would use on a photograph. So how did I choose it?
The simple answer is I played with the parameters to produce an effect similar to the internet images. I didn't consider the technical aspects, only the visual similarity in results.
The parameters I used for the Obama and x-ray images are much more conservative. It is possible to get some 3D effect on the shroud image with conservative settings; it's just not as pronounced. And even with conservative settings, the shroud image is sensitive to angle, as is the Obama image. But not the x-ray.
