General / New Mac pro and PS

« on: October 29, 2013, 12:10:26 PM »

Hello All,
I am about to decide weather I buy the new Mac Pro. I wonder if PS can benefit from the Two FirePro GPU the MacPro provides. Or will PS only use one GPU? Does PS even use Open CL?
Another Question: Anyone tried PS on the new OSX Mavericks?
Thank you for any Hint.
Greetings, Holger

General / General Question about PointCount

« on: May 10, 2013, 12:55:55 PM »

Hello Again,
I am sorry for all my questions. But I am just starting with Pscan and there is so much Information missing in the Manual. I am glad I found this Forum. Here is so much good Information.

One thing I did not jet Understand. After Aligning the Photos I get a Certain number of Points. I Figured out that the Number depends on several Factors like Max Points per Photo, Number of Photos, and Align Quality.

After I aligned I usually delete inaccurate Points by using the Gradual Selection. Now In The Infos I get a lower Reprojection Error. I guess that is the Goal? Now In the Infos See my deleted Points are still there...it say 29536 of 71234 for example. My Question is: Wich points will be used for the Meshgeneration? Does it even have an Effect on Meshgeneration if I delete Points? Or is this a Step that is only nesesarry if I want to export the Pointcloud?

Another Question:
Which Number of Points is in a god Range If I want to Aim for the best Results and want to have really tiny Details in my Mesh. Is it even Important to have a high number?
I have Scaned little things like Fruits and Small Wood peaces for testing. Is 30000 to 100000 Points a Good number or would a Million Points improve the Quality?

And one more: my Best result of Reprojection Error till now was: 0,209554.
Is it even Possible to get lower Error? Is there a Minimum Error that can not be lower?



Thank you for any Tips.
Cheers, Holger

General / High setting = bad result, Low setting= good result

« on: May 10, 2013, 12:41:33 PM »

Hello All,
I have encounter a strange thing that I dont understand. If I run the Alignment of Photos the first time with High Quality I get a messed up result. But When I run at low settings I get a better result.
This is my first strange founding.
But What I found even more strange is that if I Run now the Alignment for the Third time with High setting again I get a Good result.
So my conclusion is that best practise is to Run at low Quality for the First Run and than switch to Highquality and Align Again? Is that really improving the Quality? Or can I just run at High setting but with more Photos or better Quality Photos?

General / Will 16-bit Image imporove the Resulting Mesh?

I wonder if 16-Bit Tiff Images will result in a better Mesh-Creation? Or is  8-Bit jpg just fine.
Thank you in advance. Holger

General / Lens-Correction before importing Photos?

« on: May 07, 2013, 11:31:34 AM »

Hello, I just want to start my first Scan. I use a Canon 5D and Export my Photos from Lightroom. Lightroom can undistort the Photos by using a special Preset for the Canon 5D Lense.
Is it a good Idea to make the correct lensecorrection before I import to Photoscan? Or shall I import the uncorrected Photos?
Thank you very much.
