I killed the thread because I was getting hate mail.  The seminar was for free yet certain members here acted like they paid for it.  I was torn to pieces in private emails which I care not to re-publish.

I was criticized for giving information away for free, what I said was wrong, my cameras sucked or I didn't know what I was doing.

I have no tolerance for this kind of abuse.

Please refer to my own facebook page or Zbrushworkshops for future content but I won't ever post in this forum again.

Hey Jeff,

I'm sorry to hear that you got a load of abuse for trying to be helpful.

I understand and respect your decision but I'm sorry that it happened and I'm sure that most of us here don't condone that sort of behavior.

Cheers,

MC

as i say before its better to contact people with PMs, ASK the right way that someone contact YOU back with answer.......

Respectfully I disagree with this statement.

IMHO the preferred way is to ask a question in an open public forum and let as many "experts" answer the question as possible.... multiple heads are always better than one.  Moreover, by having the answers to questions in an open, public forum... everyone can benefit from the knowledge shared, not just a single party.

Obviously, if people want to take things further and have their own private discussions... great!  But it's beneficial to everyone when ideas, techniques and solutions are not discussed behind closed doors.

Again... just my opinion.

Cheers,

MC

Sorry but you can't stuff the genie back in the bottle by trying to keep knowledge a "secret"  that is pure BS...IMHO of course.  If people don't want to share knowledge that is fair enough... but trust me, someone else will do it... and for free and those are the people who will actually grow their business in the "digital" marketplace.  That cat is well and truly out of the bag.

Let's put it this way, I would have considered investing in the guys seminar... but now... no freaking way.

Good luck guys.

+1 with Marcel.

There are so many sub-conversations and knowledge sharing that goes on in a thread that being able to delete an entire thread just because you were the original creator is something that needs to be restricted. Allow them to delete their posts, edit them, etc. But not kill off a valuable thread.

+1  !!!!

So I think we are arguing slightly different points here, but we basically agree with each other.

Yes, I fully agree we are on the same page.

And yes, at least in my case I am talking about use in a multi-camera setup.

One thing is for sure, the kit lens that comes with the D3200 has to go :-)

Right Marcel,

So you've made my point exactly, which is the D3200 sucks for photogrammetry.

You are 100% correct it is the poor kit lens is mainly at the root of the problem with the soft focus.  I've tested this camera extensively, both with the kit lens and with extremely good prime lenses and YES there is a huge difference in image quality... the kit lens is rubbish.

Is it possible to make a good photo with the D3200 -- yes, absolutely if you have the right lens and laboratory like conditions.

Again, as you point out the D3200 seems very sensitive to mirror movement and for whatever reason it still makes less sharp images than the canon under typical conditions that would be used for photogrammetry..... so my conclusion is this....

With the Nikon D3200 I can't use the kit lens... so I have to go to the added expense of purchasing a new one.

That the camera may or may not take pin sharp images.... due to mirror movement.

So... it sounds to me like the D3200 still isn't a great choice for purposes of photogrammetry... which is the whole point of this discussion.

Again, I'm not trying to force anyone to believe my opinion.  Get yourself a 20+ D3200's and use them in your rig... then draw your own conclusions.

Cheers,

MC

Interested in the D3200?

Then I would suggest that you read this thread very carefully.... if you've not already.

This topic has been discussed in great depth previously.

Personally I would go for the Nikon D3200, because it has a significantly higher resolution (24MP instead of 18MP). Provided you can make perfect pictures (using a tripod and good technique), Photoscan will like this extra resolution.

Respectfully, I would completely disagree with this statement. You know, that's what I thought too, until I actually purchased and tested the D3200 against other "similar" offerings by Canon.  Don't believe the megapixel hype... because that is what it is.... hype.  The Nikon D3200 in both my considerable testing and experience are actually vastly inferior to the lesser megapixel Canon's.  Don't believe me, test them side by side for yourself and you will see... both Lee (INFINITE) and I have done just this and the results speak for themselves.  I know, this seems counter intuitive but the truth is that until you use these things in production and test under real world conditions specifications put forth by manufacturers and marketing departments mean very little.  The proof is in the pudding.

At the end of the day, I'm not trying to change your mind about anything.  If you like using the Nikon D3200's more power to you.  I have a hybrid rig myself which consists of Nikons and Canon's so I have no axe to grind and I'm not being a fanboy.  I only mention this in the hope that I might save you some trouble and perhaps money.

Something else that you should also consider is the cost differential between Nikon and Canon external power supplies. The cost of Nikon power supplies for the D3200 is not trivial and if you have a lot of them, it really adds up fast.  While you can find good deals on Canon power supplies the same isn't true for the Nikon's.

Good luck and best wishes in whatever decisions you make.

Cheers,

MC

No... well, not at least in my experience.  The stock lens that comes with the Nikon D3200's are of pretty poor quality.  I was unable to get truly pin sharp images with them.  I had to replace all of the stock lenses with better quality, prime lenses which made a huge difference in overall image quality.

Face and Body Scanning / Re: Worried with geometric distortions

« on: April 01, 2014, 11:52:32 PM »

Im worried with geometric distortions between two scans of the identical model, the differences are quite big... any possible reasons for this ?

Im using 35mm lenses.. and im not applying any geometric distortions corrections to my images nor cropping...

Thank you!

Wow... that's quite a big difference!

Face and Body Scanning / Re: Advantages of using full frame?

« on: February 08, 2014, 04:24:40 PM »

I know very well how full frame camera works  but i was wondering if anyone had any experiences using them for face scanning and if its worth the difference of the price, for the quality.

I've got a bunch of 5D MK II's in my rig and I don't really see that much of a difference to be quite honest.  I think full frame might just be overkill for purposes of scanning and I don't think the cost differential warrants any marginal difference in quality (IMHO). I'd rather spend the cost savings purchasing more cameras with quality lenses.... but that's just me :-)
