Post Processing / Re: My Basic & Practical Back-Up Strategy
« on: August 08, 2014, 12:00:39 AM »
Zip, Jaz, Superdisk (120mb floppy disk from 3M), Doublespace v Drivespace lawsuit (Microsoft DOS 6.2/.21/.22)

Damn you Mack, I feel old now...

So there are a few things I'll toss in on:

- Fire safe - data rated fire safes are around that have a USB bass thru, but most importantly are going to keep the contents at 120 degrees rather than normal fire safes that go up to 400 degrees (when paper burns).

- I'm up to almost 4tb of data, and it keeps getting more fun.  I don't 'clone' due to a bad file on the source drive becomes a bad file on the 'clone'.  I'm using a sync product (chronosync personally, but there are others) for the reason I can tell it to 'archive' anything that is 'deleted' or 'changed' on the source drive.  Drive space is cheap, and I can grab anything back from the archive, no software needed.

- Single drives - if you have to pay someone like DriveSavers or Ontrack to recover data, it's much cheaper for a single drive compared to a RAID set

- To NAS or DAS  otherwise - 4 most important things for a NAS are
      1) setup alerting and test it
      2) back it up to something else (and send you a task completed email)
      3) have a spare drive to put in asap and
      4) have a recovery plan
Had lots of fun recovering an old ReadyNAS - back when they used Sparc CPUs, now they've done x86 and ARM as well - thankfully a client had an old one that happened to match up otherwise SOL.  Current favorite is Synology since I can recover the disks attached to any pc booting off a live-cd.

The EF lenses would vignette like crazy, but maybe less than expected. The T/S lenses are basically MF with large image circle. A sensor size where the most common or best EF image circles just touched the top and bottom ... 12mm away .. might be usable. Or less ambitious, touched the left and right ... 18mm away.

Except that the T/S lenses would then cease to be a T/S lens because the image circle isn't big enough.

For Canon to start its own MF line requires a whole new camera system to be designed. This could go down as:
* body with integrated sensor - to just supply a body with sensor and use existing lenses (similar approach to 645Z)
* body with integrated sensor + lenses - similar approach to the 645Z but only works with Canon lenses
* MFDB - similar approach to Leaf and Phase One and leave body/lens manufacturing to others
* MFDB + body - produce a body that takes existing MF lenses from other manufacturers
* MFDB + body + lenses - introduce a whole new ecosystem (return on investment possible?)

To look at it from a different perspective, who would buy into Canon MFDB?
* sports photographers - they would need to replace all of their current lenses with newer, bigger lenses and if they don't work from monopods/tripods, they would then need to. For newspapers, etc, this ecosystem upgrade would be costly without any gain as current model FF cameras deliver what's required. i.e. no buyers here.

* event photographers - aren't going to want to carry around bigger and bulkier cameras and lenses to gigs, concerts, etc.

* wedding photographers - some parts of the wedding (non-walk around shoots) are suitable for MF shooting but not a whole lot. Those at the top end of this market are probably already using MF but it isn't a big market. With the barrier to entry being so low, it is hard to see wedding photographers being able to justify the spend.

* studio photographers - this group of the market is where most of the MF activity lives today. It's not an incredibly big market (if unit sales are anything to go by) and Canon would need to be very disruptive and aggressive to break into it.

* hobbyists - just don't have the money required (or not enough of them that do!) to make it worthwhile. When the type of photography is examined further, the group that benefits is landscape shooters but again equipment will become larger and less fun to take with you. If you're doing animals birds (in flight especially) then you'll need to buy and wield bigger cameras and lenses which is not all that attractive.

* cat photography - obviously the docile nature of cats and their fur makes them the perfect subject for MF digital photography however cat photographers do not seem to be particularly fussy about which camera they use so there could be difficulty in convincing this group to open their wallets.

There is the rich hobbyist market - someone said one of the more common hobbies for tech focused employees is photography - so there is a growing market, and to these folks the Phase/Hass system is really a reach.  Wedding shooters can do it all with their existing gear, but there is an issue in pricing - MF is an easy way to 'increase' your rates, and there are weddings that seem to have endless money available. 

Canon would have to bring a higher performing AF system - the Phase One DF+ has 3 AF points (center and either side about 1mm away from center), while Hasselblad has a single AF point but compensates for it with TrueFocus which adjusts the focus based of how you recompose the image.

Here's your MF cat image...

...., clutching the updated carbon fiber handle of a state of the art  flash powder trough. 

Can I be there when they try to explain flash powder to the TSA agents?  :D

MF is fun today, even just shooting Fuji pack film (Polaroid) on a Mamiya RZ is cheap.

Money being no object, the 1Dx and the 200-400 have some sort of secret contrast detection autofocus - I'm trying to find it now.  Based on a guy shooting the Blue Angels this last weekend, he was saying that his keeper rate is over 95% now.  I'm going to keep digging as to what settings he was using.

Having a long lens like a 3/4/500 is nice, but it can't be your only camera, and it really needs a gimbal setup or monopod.  The airshows will get close to you and a 70-200 or 100-400 in hand to track what is closer is really handy.  AF accuracy is king as it doesn't matter if you framed the shot or not, lack of AF means no shutter or a blurry photo.

The next step (beyond Strobist reading) is finding a local studio or retail establishment that offers classes.  Don't spend money on studio lights until you get a better feel for them, and some 1on1 time quickly speeds up your learning curve.

The difference between studio lights and speedlites is size, modifier options and cost - if you're doing portraits only, you can get away with speedlites 99% of the time.  Plus, you can mix in speedlites as you need to light different things individually, so it's not like any money spent on speedlites is wasted.

PCB's Alien Bees are ok, but their Einsteins are amazing and worth the extra once you add in the CyberSync bits.

Reviews / Re: NIKON Releasing a Medium format DSLR 50MP

It's relatively easy to get a Hasselblad h3DII 39 with a 80mm kit for well under 10k and around 8k. A 210mm and a 35mm LS lens will add another 5k if bought used to the price tag. MF has become much more affordable and it could soon be available again to the masses if the price trend continues. Pentax could lead the way if they released a Line of LS lenses.

Careful - Hasselblad has cut off services to the H3D/H3DII bodies & backs.  H4D-40's can be had for under 10K CPO - - I'm playing with the 150mm and look to add the 35mm to the kit 80mm, toss in the 1.7x extender and it should be all I need - except for the 24mm HCD - that thing is amazingly wide!

Canon and Nikon don't have any existing glass that will do well in a MF world - well the 17/24mm TS-E lenses work really well, but that doesn't make for a system.  Between glass and the AF systems, Canon/Nikon would be better off buying Hasselblad or Phase and leaving the brands where they are.  Even resurrecting an old brand like Contax would be better than putting Canon/Nikon on the camera (Kyocera killed it in 2002).

Hahnel for the wireless trigger, and they make one setup for doing strobes at the same time.

Instead of adapting for and purchasing a 105mm CPL, just get a 4x4 CPL from Lee or other mfgs...

Based on the end use, wouldn't doing a crop body or action camera be a lighter option?

Is the framing on the 24-70 what you want?  If so, try a heavier setup with a Glidecam or such.

Abe's of Maine, Samy's in California, Glazers in Seattle.  There are options, but they may not offer the same price point.

Software & Accessories / Re: Camera bag for camping
« on: July 21, 2014, 02:53:08 PM » ?  As Rusty is saying, start with your size, get a pack that will fit you, as you'll be able to carry more and be less fatigued with a properly fitting pack.  Figure out what you're carrying compared to who you're going with - and who is carrying what.

Where are you going, how far under foot power, what type of terrain and weather are you expecting, how many other folks are going?  A T3i with 2 lenses are better added to a traditional backpack than a special photo bag purchase.  Check out rental options on both types of bags, since you may not need the bag for another year or two and what you carry will change.

Looks like the 100mm non-L macro is what others are using

I have both the Hitech and Lee kits.  The Lee has the hoods available, so if you're shooting out a glass window you can remove all the reflection that may crop up.  I started with the Hitech but needed to purchase it all again for the hood.  Lee also has the tandem adapter, so you can stack filters at different angles.

I get some of my filter stuff locally (gotta support the bricks) and they've got both, but I had to order in the 95mm adapter rings.  Which reminds me, I should have grabbed a reverse grad for this weekend.

Canon General / Re: Seeing Rebels....
« on: July 07, 2014, 06:12:08 PM »
It's common, I find myself looking when people watching.  I think there is something to be said by brand identity, but you're missing the biggest point - these people will not purchase a new camera for at least another 5 years.  How do I figure - look at all the silver rebel's out there.  Canon and Nikon are competing with themselves as there isn't a must have feature on any current dslr made - a T1i does video and that was 2009.  The old adage was to take your photos to the next step, the dslr body on Auto is better than a Point n Shoot.  No one says what you'll get by replacing it with anything better.

Lots of folks will talk your ear off about what they've been shooting or what they're brother in law has, but generally, the compact low end dslr has 99% of what these folks want.  Nothing you tell them will get them to upgrade, let alone get a lens other than the kit zoom(s).  All these cameras will hang from their OEM straps, sit in proudly labeled OEM bags, with a few hundred shots per year.  Folks don't really care if they can get bigger, cleaner, better images - they'll just take the memory card down to the local print shop and get some 5x7's and call it a day.

I worry that the slacking demand for low end cameras will adversely effect the development money that Canon and Nikon have going forward.

Welcome Diane,

Give us a little more info as to what tools you're working with, and there are lots of options to consider.  Generally speaking, as stated above the 24-70 & 70-200 f2.8 zooms are the wedding workhorses - other lenses are used for specific looks or shots, but entire weddings are shot with just those two lenses every day.  If you can swing it, you won't regret investing the money into either of the 2nd gen of these lenses.

Depending on what you want, the 24-70 VC from Tamaron or the 85mm f1.8 or the 135mm f2 are all options that will work in dimmer locations.  Also consider the high ISO performance of the newer FF bodies (5d mk3/6d) may be your best place to put cash.
