Photography Technique / Re: What Lenses Do You Use for Panoramics?

For holiday (ie casual) pano's and stitching

40mm Pancake vertical orientation
pre-processed in Dx0 Optics
stitched in PTGui
re-touched in PSE

Love that little pancake, must dig out some examples but will have to downsize them a heck of a lot not sure how that will turn out

(Also influenced by Sporgon's comments)

+1 for the 40 it's a brilliant daytime street lens, no one gets pissed when you point it at them in tight spaces it doesn't get  bumped and has little if no theft value

love the iconic TT please post a few pics, sounds like you have a really great vantage point!

Am I the only one looking at this thinking st1 & a pancake please  :o

Software & Accessories / Re: Which Software to convert Raw files?
« on: May 27, 2014, 07:07:40 PM »
I use DxO as my primary software for RAW. The PRIME noise reduction is incredible, virtually eliminating noise without loss of resolution. Further processing and sharpening are done in Photoshop as it has some nice tweaks and its "layers" is very useful.

Have recently moved from DPP to DxO, I try to do as much as possible within DxO but for some tweeks and cleaning PS or equivalent is indispensable.

To add a footnote to mt. S comments on possibly requiring the pro version, the cut off is actually determined by the size of the image in megapixels not megabytes this is a very important distinction as if like me you do stitching and panos you my require the pro version no matter what camera you have. DxO do not make this clear at all.

All depends on what kind of holiday.

I'm recently back from a short city break to Rome, decided to challange myself and just go with an aps-c and 40mm.... "Rome on a Pancake"   :P

It really was great fun, yeh you have to move your feet a bit but a great street lens so small nobody cares  ;D and great for high res stitches/panos

If it's not a safari, keep it simple, have fun

Sorrento Harbour. We had a dinner one evening at a restaurant overlooking this, I could barely look at what I was eating given the view I had  :D

Marina Piccolo on Capri. Sat on the beach for an hour waiting for our boat to pick us up (wishing I had gone for a swim now looking at that picture! Would love to go back to Capri and spend more than a day there. Absolutely stunning island. Opted not to go into the Blue Grotto, from pictures on Flickr it is something I won't skip on next time I am there!

Delfino by any chance?

and the Blue Grotto is well worth seeing if for nothing more than a trip in those little mad 'buses' to get there!


16-35 yussss..... The 17-40 was on my list but not now. That's the Christmas bonus spent already, just need to get to Christmas!!!!  ;D

Dear friend procentje20
Wow " Their first reaction. "The volunteers are out of focus"  "----I ( as Photographer) love your photo, that show the main subject is sharp in focus, and most all of the volunteers are good blur.
BIG BUT = As the "  the work of volunteers at a triathlon in my home town. " = 99% of the VOLUNTEERS are Volunteers, Many of them Big / High position in their business in your Home town, And They working hard  with out pay, And The Most important thing in their lifes are have the good Photos ( OF THEM) in the Publish/ Magazine/ Pamplets--To show off that " Here are ME, , who working hard , to make this event Success---MOST OF THEM do not care , who are the winners---At all.
YES, I have learn from more than 10 race like this-----The first one try to do same thing that you did, AS THE REAL PHOTOGRAPHER, not point and shoot to get every thing sharp in focus, And I Miss alot of the Volunteers/ Staffs's Photos---Just Pin point to the Public Racers.----YES, I AM WRONG.
Yes, I ask the Boss( Of the Race) , why They do not like my " PHOTOGRAPH'S IDEA Photos ", And He explain to me like I tell you.= The Most important Photos = The Photos of their staffs and The Volunteers, Including  another Volunteer Photographer too.---If No their Photos on the Book/ Publish or Pamplets after  the end of Race---Most of them will not come to help in another race.---YES, Most important Pictures = BEFORE THE RACE/ Preparation, and Clean up job, by Volunteers. To record the Photos that they can use as the Volunteer project, Not The NO NAME WINNERS, who just one time race.

Yes, After the first Race/ Volunteer----I know , who I will shoot the most---The Boss and all / Yes, All of the Volunteers.


I think the expression is 'Nailed It'   ;)

PowerShot / Re: New PowerShot & EOS Cameras to Offer DOF Control?
« on: May 05, 2014, 04:50:00 PM »
Sounds to me like a mode in which the camera determines the subject near and far distance and sets aperture to ensure all subjects are in focus.

take for example a shot of a group of people.  face detection could be used to determine the distance to the subject closest to the camera and the suject farthest from the camera, then select the aperture that mathmatically satisfies the DOF with that lens.

Sounds like a cool feature for consumer level cameras or even for shooting video if it was dynamic enough to adapt to the changing environment in real time.

My original EOS650 had that.

My old 500D still has it  ;D

Why do the etchings always have to go in the same direction?
I guess it's how are they cut out? what do they use, a saw  ;D

Well, there is no specific reason why they couldn't etch some additional sensors in the perpendicular direction, but it would be costly. The way sensor fabrication works is by etching the silicon with extreme UV light via a template. The template is oriented in a single direction. The wafer is moved underneath the light beam so that multiple sensors can be etched. Etching of a single sensor is a multi-step process, with various steps involving masking, etching, dissolution of masks, more etching, doping and layering of new materials, masking, etching, etc. This stuff has to be precise to the level of a few nanometers at most, so it is entirely automated. Rotating the wafer to etch additional sensors in a different direction introduces a source of error that could hurt yield.

Fascinating, must be very impressive to watch, though I guess not actually viewable. Thanks for the enlightenment!

Surface area of FF => 864mm^2

If they can only get 20 FF sensors out of that, they have about 58% losses. 

This is an 8 year old white paper and nobody mentioned these mistakes before?

That's very interesting if indeed that does translate to about 58% full frame sensor losses per wafer, even if it was 8 years ago.

I made a mistake (maybe Canon has a job offer ;-)), corrected it in my last post. It should be

Surface area of FF => 864mm^2

If they can only get 20 FF sensors out of that, they have about 47% losses.

It isn't exactly 47% loss. It's 64% of the area is actually used to print FF sensors. If this diagram is any indication, then they actually ETCH exactly 24FF, or 80APSC on a single 200mm wafer:

The actual losses would be out these numbers...so accounting for defects and whatnot, actual FF yield would have to be less than 24, and actual APS-C yield would have to be less than 80. Assuming they actually get 20 FF out of 24, the loss is 16.7%.

That assumes that the article was clear about the size of wafer used to produce APS-C sensors...which it is not. Since a 300mm wafer can handle about 212 APS-C sensors, and since the article states that around 200 APS-C sensors are made from each wafer, it makes sense that Canon is manufacturing APS-C sensors on 300mm wafers, rather than 200mm wafers. Either way, they clearly have a higher yield off smaller sensors.

Why do the etchings always have to go in the same direction?
I guess it's how are they cut out? what do they use, a saw  ;D
