Site Information / Re: Problems uploading images.
« on: November 10, 2011, 10:12:16 AM »
One last thing... check your file permissions... I upload files to different companies websites daily whom I do commercial photography for... Sometimes, rarely, but it happens, where a computer files permissions will get turned off where other computers other than your computer including servers cannot read the file.  Right clicking on the file, looking at properties, and making sure your computer is read/write, and the other two settings (network/everyone else) is at least read.  Doubt that's your problems but when all else fails check it... if you have files saved on a network or external drives, sometimes those external devices and especially networks strip permissions from files.

Lenses / Re: Does a lens hood reduce the light?
« on: November 10, 2011, 10:07:31 AM »
Short answer, no, long answer, it blocks the incident light that could cause flare (causing low contrast and washed out scenes.)  It will reduce the light you dont want in your scene assuming you dont want that light in the scene.

you guys are very lucky in there photo gears are abundant and the prices are very competitive unlike here in australia all the gears are priced sky high

Yes but on the other hand... you live in Australia!   :D

You beat me to it... the trade of is april lives in beautiful australia... Visited there a while ago and waiting til the day I could visit again... (minus the 14-16 hour flight out there that is)

EOS Bodies / Re: Pro camera insurance USA, besides State Farm??
« on: November 09, 2011, 04:07:49 PM »
I have all my gear attached to my homeowners as an additional rider.... I have allstate.  They have like 2 levels of coverage if i remember right... one was cheaper and covered theft and such but it kinda had to be "within the home" and then they had an itemized one where it's 0 deductible and covered mysterious disappearance and such... My 5D2 and 24-105 alone was like $80 for 6 months extra and the rest of my gear also was added for I think maybe $120 for 6 months?  Not too bad... I think if you rent you could add that onto your renters insurance...

Lenses / Re: step up/step down

I'd recommend step-up before I'd recommend step down, but as long as it doesn't vignette then go for it... That's what they're made for.

Canon General / Re: Dynamic Range - Digital sensors
« on: November 09, 2011, 09:20:43 AM »
DPR rated the 5d 2 with a DR of 8.6ish with as-is settings but with highlight priority bought you another stop in the highlights. Others said the 5d2, such as art adams, that the same camera has 11+ ev. Fact is there is no real benchmark everyone can accept without running our own tests so arguments such as this is really futile.

For what it's worth, DXo Mark, who rates the sensors rated the 5d mark 2 with a dr rating of 11.9 ev. I know they can be questionable by many photographers but take that for what it's worth.

Question: Can someone please explain why digital sensors have a much narrower dynamic range then film ? This is apparent to anyone shooting outdoors in bright light - the shadows are black and the skies blown out.

Will digic 5 improve this? Is it possible to improve it?
The DR that an expert user can achieve using aggressive eposure or exposure bracketing together with optimal development of raw files is quite different from what the average user gets with AE and jpegs.

For the expert/nerd, the main limiting factor is the camera sensor. Digital sensors are basically linear with an obvious saturation point and a noise-floor. Film is (I believe) very different, with smooth roll-offs in high-lights and in shadows. Using one definition one might claim that film has a lot of DR. Using another definition, one might claim that film does not give an _accurate_ recording of the scene brightness over such a large DR. In the end, it usually our eyes that are the judge, and if you prefer the look of film I can only suggest to keep using that.

I do believe that many comparisions of film vs digital is unfair. I.e. digital is compared to film on films terms. For the expert user, this might not matter as she will choose based on her own knowledge. For novices, this could lead to false conclusions.

-h

While I dont consider myself a nerd, Film had sort of a soft S curve in the DR and gradual decline in the shadows/highlights, but just like digital, It was a tad more forgiving in the highlights in negative film (film was essentially transparent (negative) once processed and the exposure burned the image onto it... If you over expose or underexpose maybe 1 stop, you could always compensate by over/under developing...

People give digital too much credit... Film, you had to expose properly (same as digital), process it (raw conversion to photoshop/lightroom/aperture), and in most situations, print with contrast filter, dodge/burn, manipluate, etc (post-processing in photoshop, lightroom/aperture)... Just to take a image taken from digital and scanning a slide film and measuring ranges, I'm sure they would be quite comparable... but also then you have to take in to account processing and post processing... All that will affect visible DR and needs to be taken into account when comparing oldschool zone prints.  There's a lot of stuff to take into account

From what I remember... BW negative film had natively around 7-8 stops of range, you were able to push/pull the film in processing to get some more range, but maybe a stop or two more... Color Slide ISO 50 film you were looking closer to 11 stops... Paper only had closer to 6-7 depending on what paper you were using, RC or standard.  Zone photography allowed you to make the most out of your film/processing/paper to get the absolute most out of your DR.  Digital, other than maybe HDR, which may or may not be perceptually loved, is the closest photographers have to Zone Photography... 

Whether or not digital has more or less DR is dependent on skills, exposure and processing as well as if this is just going to be viewed on screen or printed, if printed, what printer, inks, paper combinations you are using.  In Film we exposed for the shadows, printed for the highlights... digital, we got to do the reverse, expose for the highlights, print for the shadows (just like you would if shooting slide film, you can boost up shadows, you cannot regain lost highlights).  Most people forget this technique and become somewhat lazy.  I think cameras are starting to get to the detail quality that we expected from film, but you will need to really learn exposure to get the most DR Possible.  It is not just camera dependent, it's so much more.

I just got an email from Canon saying a new batch of instant rebates for 5d II, 7D, and 60D... (7D and 60D additional rebates with certain lens purchases)... up until thanksgiving...

1632
When I bought my kit from adorama, it was a 5d2 24-105, battery grip, spare battery, case, 8GB UMDA Sandisk CF, remote release, and software bundle for $2990.  When you take out the goodies It would put the 5d2 kit near 2750 give or take (after I bought that it jumped up $300 the next day and $100 more once the rebates ended)... Must have been a typo on the price?  But they honored the price.   

That's a great deal if it was a Canon grip. All those items add up.

The irony was at the time, the kit with JUST camera and lens was $3199 but that same kit plus all those extras was $200 cheaper... It was a no brainer...

EOS Bodies / Re: 5DM2 Purchase From Canada (Henrys) to USA
« on: November 07, 2011, 02:09:47 PM »
Brokerage Fees are the fee the shipper will charge you to process the importation of the product.  USPS may not charge you anything.  UPS definitely will charge you brokerage fees for ground shipping but usually not for air shipping.  Note that my experience is based on shipping from the US to Canada.

I haven't shopped at henry's however I've heard great things about them...  When I purchased my 5d M2 a few weeks ago they didn't have them in stock and I got a great deal from adorama on a kit which was lower than the regular asking price non-kit, probably was a mistake on their part but they honored the price... Anyways, regarding the brokerage fee's, I understand in some situations, there may be duty fee's and such to get through customs... As far as UPS charging fee's, I order most my photography stationary from Boss Logo in canada and they ship UPS...  I've never gotten any extra fee's that wasn't built into the shipping fee's...  USPS I haven't had a problem per-se with shipping from canada to USA however I suppose certain companies can elect to COD the import fees/customs fees and not pay it, especially if they offer "free" shipping...  Perhaps this is what that is?  Good luck.

EOS Bodies / Re: Final shopping list for tomorrow..

I keep my lowepro bag when I need to carry a lot of gear and cant bring the pelican, but travel and any professional event, my pelican is my go-to case.

How does the Pelican 1510 do for backcountry hiking or walking through an urban setting?  :P

Actually, I have a Peliacan-Storm im2500 (the Storm equivalent of the Pelican 1510, i.e. airline carry-on hard case).  The problem I had with just a hard case for travel is what you do with the case when you get there, i.e. how do you walk around with your gear?  A little inconvenient to drag the hard case around.  My solution was to remove the padded divider system from the Storm case, put the gear in the Lowepro Flipside 400 AW, and put the Lowepro backpack inside the Storm case.  Sturdy, lockable protection for travel (also handy if you're forced to check you bag for whatever reason), plus the convenience of a backpack when I get where I'm going...
he said he uses the pelican for travel and events. i assume for travel he means by flying which totally makes sense to have a pelican and you pack a smaller bag for when you get there for your daily needs.and for event photography nothing wrong with a pelican there again makes total sense to me.

To be honest I dont do much backcountry hiking and shooting, even though I should because of where I live, it's just one of those things where that's not where I make my money, commercial is... If I'm flying, if i'm meeting clients, if I'm away from home, if i'm at a shoot, my pelican is usually with me... If i'm on the go, at an event, if i'm out with the family doing whatever and I need lots of gear for god know what reason, then the lowepro it is... But usually in that event I usually have a feel of what I need and bring only what I know I'm going to need (less is more)... As i said, it's bulky and a pain in the butt in some situations, but in the end of the day I know I could endure some catastrophic event and my gear will be good to go.  When I used to shoot 4x5 large format in the studio, we would have our beefy Bogen tripods in sometimes awkward angles and you need to be behind the glass with a lupe to check focus... we'd use pelican cases as step stools so we could get behind the glass enough to check focus.  I love 'em.  =)
