My theory is that there was an interruption of the LED flash for a brief moment while the exposure was being made. As the iPhone camera uses a rolling shutter, this would result non-illuminated area on the part of the sensor that was being read while the light from the flash was absent.

I had a similar theory but wasn't sure if a break in the flash would produce a band. Interesting about the rolling shutter. Thanks for replying!

Photography Technique / Diagnose this error

Hey guys I have a real puzzler for you!

Background story - while discussing THAT dress recently with one of my colleagues she remembered a photo that she once took that looked bizarre. I had a look and could see where things went wrong and explained how it could be fixed. It was fun diagnosing her photo fails so I asked her to send another. The latest one has me stumped so I thought I'd get some more technically minded folk involved with her permission.

This was taken on an iPhone (I think the 5 or 4s). What is causing that bar in the middle?

Canon General / Re: Spartans, What is your profession?

I work full time as a performance supervisor for an English teaching company in Japan. I manage 16 English instructors.

I got into photography about 4 years ago. I've made a little bit of money doing some paid jobs including a wedding and one corporate shoot that went into a magazine. My most recent paid job was a fashion shoot for a small startup business (just two guys selling dresses) looking for a cheap photographer.

I make enough money from my main job to pay for my GAS but it's nice to know I can earn a bit of money from the gear I buy to justify it!

EOS Bodies - For Stills / Re: What is that dot on the 5D3?

Pretty useless these days.  Make wifi standard and do remote shooting from your smartphone.

Given you have to connect and it drains the battery on both devices, I love the idea of wifi/smartphone combos but in practise only use it for image review or remote liveview..  Having a small very light thing to carry around as an easy remote trigger is great in my view.

.

I used wifi live view shooting via my iPad and 6D and got about 200 shots before I had to change batteries (on the camera). Not great. IR still has it's use IMO.

We might get an announcement later in the year. I think we'll get slightly more MP  (around 20) and possibly more fps and naturally dual Digic 7 to handle the speed. A lot of eyes will be on improvements in DR and high ISO noise control.

Features I think we won't see - Wifi and touchscreen. GPS maybe (based on the fact that the 7D2 has it).

Lenses / Re: First Tests: Canon EF 11-24mm f/4L a Winner
« on: February 28, 2015, 12:57:39 AM »
It's a shame that most of the LR tests are done wide open only, since the tests are so good there. Let's face it. For the most part, people don't shoot 16-35 IS, 11-24, 14-24, etc. at wide open, but more likely f/5.6-f/11, so I'd love to see the lenses tested at say f/7.1 (enough to avoid too much diffraction but also to get more of a sense of landscape shot performance). (and when you do shoot f/4 and faster and especially f/2.8 and faster, wide open, you are not as often caring about the edges corners as when stopped down a bit)

Fair point and I would like to know f/8 performance too however if it kicks ass at f/4 we can naturally assume it will be even better at f/8! For a lot of lenses though wide open performance is a key factor in deciding about it's usefulness. Since all lenses perform decent stopped down it wouldn't really give much away about the flaws of the lens. Wide open is where we are likely to catch those flaws.

Thanks for the responses guys!! I may have to consider the 17-55 efs. But spending $800+ for a lens, I would prefer one that I can use on both full and crop cameras.

About the 17-55 efs, is it true that it have a problem pulling dust inside the lens? And the IS system on the lens; how is it? Is is smooth or jerky?

Do you need the f/2.8?  If not, the 15-85 is great.

The 17-55 dust problems are over blown, and the IS is quite good on both lenses.

You could buy a used 17-55 and sell it later, probably for about what you paid for it.

I agree the dust wasn't an issue. Every lens gets dust inside the front element eventually. The front element on the 17-55 seems to magnify the dust. I opened mine up once so I know from experience! I wish I had left it alone!

That lens was magnificent. I loved it. So versatile and the IS was good for at least 3 stops. Focused really really fast! A perfect match on crop but especially matched nicely with a 7D2.

Build quality could be better though for the price but what you should do is just buy a used one in good condition. They can be found for a bargain now and all that dust scaremongery just makes it cheaper! (Annoying when you sell it though!)

I am still fine, no symptoms at all
I find that very surprising, given how little gear you have in your signature line.

 ;D ;D ;D

Could totally fit a 600LII in there! He's slackin'

Photography Technique / Re: What is your keeper rate?
« on: February 23, 2015, 08:14:22 PM »
I had a photoshoot on Saturday there. Shot approx 350 shots. Controlled situation / studio like conditions so there was more time to get it right in camera. So far I'm down to about 100 definite keepers. That's more than what I expected!

I reckon next weeks shoot outdoors will have a lower success rate!

any reason all the new canon lenses are F4 ?

Explain why you need f/2.8 at these focal lengths please. Please don't say "low light capability" because if you are using a lens like this indoors in professional use you will almost certainly be using a tripod. And upping the ISO nowadays by one stop isn't a big a deal as it used to be. The 6D works nicely even an ISO 6400. I don't even use that for stars in the middle of the night so unless you are shooting in a cave in complete darkness, handheld, with an older generation camera - the reason is pretty clear why f/4 is good enough.

If not - 14mm f/2.8 is your friend.

What experience do you have shooting events?  And though you may be satisfied with ISO 6400 images, there is no arguing that lower ISO looks significantly better.  I'd rather have a non-IS 2.8 for shooting typical indoor and under-tent events than 4.0 with IS.  People move!  Colors, bokeh, contrast, and, of course, sharpness all look better at lower ISO.

I would have bought a Canon version of 14-24mm f/2.8, but not this one at f/4.  I'm sure it will test/review just fine in terms of IQ for landscape and still-life,  but for people photography, f/2.8 is still the standard, especially for $3000!

This isn't the max aperture of choice for photojournalists, sports, or wedding photographers.

Enjoy it for what it is, but why berate those of us who do value 2.8?

I have shot weddings and events. I wouldn't use an 11mm lens (no one ever has because it hasn't existed before!) for weddings though. And if I needed f/2.8 or wider I would use a prime - that's what primes are for IMO.

There are a bunch of lenses out there that could do the job - Canon 14L, Ziess 15mm, Canon 16-35LII, Canon 24L, Samyang 14mm, Canon 24mm f2.8 IS to name a few.

The 11-24 is not meant to be a general purpose lens just like the 17mm TSE isn't a lens made for wedding photographers. My point is if Canon tried to satisfy everyone we would end up with a compromise at best and then no one would be happy. I don't want to see that.

Photography Technique / Re: POLL: Do you wide-screen frame/crop?
« on: February 22, 2015, 08:54:10 AM »
I hadn't even thought about it until now. I always try and maintain the original proportions even after cropping just because I thought that is how it is meant to be and how we are used to looking at images. Plus it makes it a whole lot easier when trying to send to print.

Personally, I love the widescreen formats and will now keep them in mind when shooting!

Some discussion here: http://forum.luminous-landscape.com/index.php?topic=76197.0

If your graphics can drive it, I wouldn't even think about anything less than 2560x1440 or 2560x1600.

The Dell Uxx14 PremierColor series monitors have generally received good reviews. The U3014 has had some firmware and card reader issues, but those seem to have been straightened out. I don't know if any of those monitors are available in your location or if they are within your budget.

My integrated graphics card can handle up to 1920x1200 through HDMI. Going higher will require a dedicated video card. Might as well gear up for 4K/5K if i'm to stretch my budget that much. Also 30" seems freaking huge for my working distance of half a meter, i would settle for anything between 24" and 27".

This. Calibrate your monitor.

Also quirky thought of the day. While we sit and view our lovely images on nicely calibrated wide gamut monitors most people who will be viewing your pictures will likely be doing so on iPhones and other (probably) non-calibrated screens. So, what do you make the image look good for? You or your viewers??

Yes, i've put thought into this as well. Most of my pictures would be shared online, but i would like to be able to print those i care the most for. Then there's another question: printer calibration. I don't plan to buy a printer, any eventual printing services will be carried out by a specialized provider. How do you know how and if their printers are calibrated properly?

You don't. You just test print until you get something that closely resembles what you want!  :P

But seriously - you can talk to the lab and ask them how to go about it and what settings you should use etc. they might provide you with an ICC profile for your monitor.

This is quite interesting - how do you guys use the export to catalog function? I tried making catalogs for various shoots but now I'm back to just one big daddy catalog. When it gets too big I export a chunk off. I have a 2010 - 2012 Catalog for example.

I mainly use collections and collection sets to organize everything and leave folders the heck alone. Still not using keywords properly though. I'm not really a keyword kinda person. I find it laborious. Plus I always forget what I labelled an image as!!

My collections are labelled by basically just the types of stuff I shoot. And I have one collection for portfolio.

Thereby creating multiple catalogs can make little sense unless you have a very good reason to do so - it can make sense for example to have a "personal" one, and a "professional" one if you want to keep  really separated say, your family shots from those you make for your customers - maybe you don't want to show your personal shots to a customer by mistake.

I find performance takes a major hit as catalog size increases, even if it deletes rendered previews on a scheduled basis. Therefore I don't work in my master catalog. I create a new dedicated catalog for each individual shoot or day, depending on the situation. Once I've completed my culling/processing/exporting, I open my master catalog and import the new one to it. This way I rarely have more than a thousand photos within a working catalog.

That's great .... until you try and gather images from different shoots into one space like say for example you want to find your best wedding shots to showcase to a client. Now you have to hunt around various catalogs and then re-import them all into one master one to create a central portfolio that you can edit.

Yup. Know that from experience.

4000+ images now in one catalog and no slow down. I read that it's a combo of things that slow down LR including how many of your images have been edited and how many local edits such as the adjustment brush you have applied. Liberal use of the brush slows down my laptop which is my biggest annoyance. Other than that it seems to handle several thousand images in the library fairly well.

Edit - sorry I read your post wrong and see that you first do the culling then export then re-import leaving you with just the goodies but even then I think you can eliminate a step here by simply importing all, culling and then you're done.
