JD,
Slightly off topic...
As someone who shoots a lot of product images, I can also say that in addition to dropping in the screen image, the photoshopper got the reflection angle in the glass completely wrong on the second image (Sony). That's the kind of stuff that drives me crazy.

Set a product at the same angle on a reflective surface, and you'll find the reflection goes in the opposite direction they show. That's just lazy.

Back to on-topic...Though in all fairness, even Apple drops in screen images after the product is shot.
(So do Canon and Nikon.)
It's just so much easier.

here are two offenders.

Squeeze every ounce of IQ out of a camera before denouncing it. I have yet to find a canon camera that truly limits my creativity.

If a system limits you, switch because your capping your creative potential.

wise words

Indeed.

Canon General / Re: What's your definition of "Pro"?
« on: February 11, 2013, 12:16:53 AM »
I'm really impressed with the depth, insight and humor of some of these answers!

My definition of the difference between an amateur and pro has always been summed up thus:
Given the time and perhaps a little luck, an amateur photographer can capture a perfect image.
A pro does it while running a fever, after 4 hours sleep, and in bad weather...all on a schedule.

(Honestly though, I kind of prefer some of the other definitions.)

Technical Support / Re: Printing large images - help needed!!

Wait a minute, I assume these programs for enlarging aren't free? Photoshop alone can't do the job? I was worried about the big one now. Maybe I'm out of my depth on this one.   :-\

No, they aren't free. But they aren't bad, and you only have to buy them once. I assume you're making money in this business since you referenced a 'client'. Think of these programs as tools to help make money.

And don't let the first time learning something panic you. We're all always 'out of our depth' the first time. You'll do fine.

Technical Support / Re: Mirror fallen out of 5D - self repair ?
« on: December 29, 2012, 02:27:37 PM »
Our Building Panoramics 5d MK1's mirror has finally fallen off its perch after seven years.

I know this is a design fault and Canon modify the mirror free of charge, but has anyone tried to glue the mirror back themselves ? It seems like a very light dot of super glue on the four little cushions / adhering points would fix it.

I'd appreciate experience from anyone who's fixed this themselves.

Thanks,

 :o
You don't use super glue inside a camera! Cyanoacrylates (super glues) outgass a slight white plastic 'fog' which adheres to anything close by...like sensors. And then solidifies. That's why you'll sometimes see light white fingerprints inside the superglue package itself.

That discovery, by the way, led to putting super glue in a sealed box like an aquarium to 'pull' fingerprints from objects that traditionally couldn't be fingerprinted. The resulting residue is basically permanent and cannot be removed.

Hey guys, I need your combined wisdom and expertise on this issue - I've been asked to provide two images to a client who wants to put them between 2 panes of glass for a wall mount. The size of the images would be as follows

bathroom : 210 cm x 185 cm

corridor : 263 cm x 198 cm and 247 cm x 198 cm (its in two pieces).

See pictures that I was sent.

I mostly have images taken with 18 MP cameras (550D and 7D), and a few with a 21 MP (5D II).

What resolution is best for this type of thing? Is it even possible to print something that big with 21 MP?? I assume there must be a way. Any help would be greatly appreciated. Thanks!

Z,

You've gotten some pretty good advise already, especially from seanature.

I just fiinished up about 30 such images for trade show booths for the upcoming CES show.
Most printers will suggest printing at about 150dpi for extremely large images. Since we own a large printer, I'll sometimes go to 240-300dpi for the smaller (48inchesx36inches) and save the 150 for the larger booth backgrounds. (15 feet x 45 feet )

Please note two important points: 1. File size goes up exponentially. Doubling a linear dimension will make the the file 4x bigger, etc. I work with many files that are 6 and 7 gigabyte in size. Make sure your workflow supports the room. (And become familiar with photshop's large file format, since the PSD format won't handle it.)

2. I tend to disagree with other comment about 18mp being enough resolution, especially for that 2 wall wrap-around. You really don't have enough resolution without a high quality up-sampling program. I use a 5D2 and one of two programs with photoshop:
Perfect Resize (formerly Genuine Fractals) (http://www.ononesoftware.com/products/perfect-resize/)
and
PhotoZoom Pro (http://www.benvista.com/photozoompro)

Perfect Resize tends to work better for natural subjects, PhotoZoom Pro w/S-spline Max tends to work better for man-made subjects.

The other advise about using raw 16-bit tiff file formats was spot-on, as was finding and working with a good printer.  Comments about buying your own printer should be taken with a grain of salt. Our printer was just under $10,000 USD. I believe it uses 12 ink cartridges at over $100 a pop, and two print heads that need replaced about once or twice a year at about $400 USD each. (We won't even talk about the rolls of glossy photo paper you'll consume.) Unless you want to get into the sign/banner business, it's best to focus on your photography. (pun intended)  :)

Canon General / Re: Advice for potential rate/releases
« on: November 15, 2012, 03:14:04 AM »
Everyone has given you good advise. Something to consider is that 'going pro' is not something to dabble at. It's a real business, or it's not a business at all. You've already paid for the equipment you have...that's great. But that gear won't last forever, and you'll need to anticipate replacement costs. Then there all the hidden costs that tend to creep up. Dabbling at professional photography is as practical as being a little pregnant...it's an all or nothing kind of thing.  ;)

Lenses / Re: Canon Announces New Lens Caps!
« on: November 06, 2012, 09:01:10 PM »
It would be nice if, one day, someone produced lens-specific caps with the focal length printed on them. Four of my lenses, with identical 58mm caps, would be hard to tell apart in my camera bag were it not for the white stickers I've put on the caps, on which I've written the focal length.

By the way, I'm intrigued by some of the comments about the look of these new caps. I admit that I'm blind to some aesthetic cues (due to the way my head is wired!) but is it really possible for a lens cap to be judged good-looking or not good-looking?  :-\

I agree. Additionally, I've always thought it would be nice to have color-coded caps, so I could quickly spot the right lens from a short distance.

Who uses lens caps for X sakes? I'm sure all amatures have a big fat 'what ever' filter screwed to the front of their lens, so why the lens cap? To prevent aspeck o dut ever to invade your precious piee of glass? God forbid. No, seriously, who uses these, and why? Anybody ever had his / her lens damaged because the lens cap wasn't on? Very interested in your replies!

I find your comment rather odd, so I'll try to answer:
1. I use lens caps front and back on all the lenses in my bag....as does every other pro I know.
2. I'm not an amateur (note spelling). I've been a professional photographer for over 30 years.
3. Dust doesn't 'get in' a lens from the front element.
4. I don't typically use filters, but depend on the hood to keep the lens from getting scratched or damaged in use.
5. Disclaimer: I've got an old 24-70 L assembled on a 7D kept in a fast bag with just the hood and no cap, but that's mainly because I lost the cap and have just been too lazy to replace it.

In short, seriously, do you really not use lens caps for your lenses? I suppose you leave the camera bodies open, with no body cap, as well? Thrown all together in a plastic grocery bag, maybe?


Thanks for the English lesson! I'll be extra careful next post.
No, seriously not all here are native English speakers! So please try to control yourself...

Anyway, all the working professionals I know put there lens hoods on (plenty of protection), and 'throw' their lenses in their bag when 'changing' (and, yes, usually WiTHOUT cap on the back end!)   Some of us actually see lenses and bodies as tools, i.e. pieces of equipment designed to be used and, if necessary, abused.

Control myself? Wow. If sarcasm were an artform, you are truly aspiring to greatness.
On the other hand, if you are not a native English speaker, then I do sincerely apologize for correcting your spelling.

Like you, I also see my gear as tools...my living depends on them. That's why I can't risk damaging them!
I was taught to take care of my tools. You may not have been.

As a professional, I've broken many lenses...and bodies...usually due to my own carelessness. Probably more than you've owned. Most were damaged from dropping, but yes, if you do this long enough, I've damaged front elements on expensive lenses when the lens cap popped off, or I was just lazy and didn't put the cap on.

I've watched a Mamiya RZ67 bounce across a floor. I've seen one of my Hasselblads shatter into thousands of pieces when dropped onto concrete. Twice I've watched two fully loaded Nikons atop tripods fall to the floor in pieces when I tripped over the sync cords. And yes, I've heard the screech as hardware such as a film back scraped across the unprotected front element of lenses.

It has cost me many thousands in repair bills, but I try to learn from my mistakes. If I allow a $3,000 lens to be destroyed on a shoot I charge $3,000 for, my net profit is zero. That's just bad business.

I humbly suggest you learn from my mistakes, otherwise you'll eventually learn it the way I did.
PROTECT YOUR INVESTMENT!

Crap. I just placed an order yesterday for 4 more 67mm and 77mm Nikon caps. (I've been using Nikon pinch caps to replace my fumbling %^&* canon caps for years, but would much rather have Canon make them right.)

Oh well, timing is everything.  :P

Going from CA to Fairbanks...I don't think you quite grasp the weather difference. As I type this it's 60degF here in Colorado Springs. Wunderground shows a current temp of 9 below zero in Fairbanks. Fairbank's historic lows this date: -41degF.
They're predicting a blistering high of 1 for tomorrow....and this isn't even the cold season yet.
In the summer, AK is an incredibly beautiful state. But there's a saying in AK: "We live for the summer...BOTH weeks of it."   ;)
