Photography Technique / Re: Noise in 5D III - Concern or my fault?
« on: October 14, 2014, 02:06:36 AM »
Bad choice, only use full iso stops (100/200/400/...) or you lose image quality.

I am fairly certain that is an urban legend with no basis in reality.

I'd be quite interested in hearing the opinions of a few of the forum's gurus on this topic.

Software & Accessories / Re: Cloud storage

Happens that I just finished researching this for my daughter. I ended-up recommending that she trust her files to the cloud-people at Backblaze because it is the easiest of the cloud-backup services to configure; on a Mac, you literally just install it and you're done! That is pretty slick! And it's a bit cheaper then the competition.

However for my own cloud-backups, I use CrashPlan because their service is much more customizable. With Crashplan your deleted files can be retained in the cloud forever, not just 30-days as is the case with Backblaze. Also CrashPlan allows for unlimited versioned-file retention, and restored files will keep your original folder organization. Crashplan also works with removable/external &/or network drives much better than Blackblaze. With Backblaze you must mount your external drive at least every 30-days or it will be considered deleted and subsequently removed from their cloud-backup! Lastly, for an additional fee, CrashPlan has a "seeded backup" service where they will send you a portable hard drive (that you fill with your initial backup data) then return to them so that your first terabyte of data doesn't take (literally) weeks & months to send up to the cloud.

Please... Inquiring minds would like to know...

Have you ever tried the "Merge to 32-bit HDR" Lightroom plugin by HDRsoft (the Photomatix folks)?

http://www.hdrsoft.com/download/merge_lrplugin.html

I find it to be a much more straight forward way to get a virgin (NOT tone mapped) 32-bit HDR file that can then be processed in Lightroom (or ACR). It does not require Photoshop and allows me to simply stay in Lightroom for all my basic post-processing. Also, the resulting 32-bit files, that can be really big as you know, can be cut to half-size (while retaining the entire 32-bit tonal range & edit-ability) if you select the "use half floating point format" option.

Everyone that prints enough of their own photos these days will eventually discover Red River Paper.

I'm responsible for the care & feeding of an Epson 4900 and I'm not at all shy about spending money on quality supplies. I print a lot and these guys offer top-notch quality and the best customer service in the business. Period.

Thanks for the great info! Saved me the trouble when I get my f/4 next week! All-in-all the f/4 looks to be a tad more forgiving (when coupled with a Lee filter holder) as compared to the f/2.8.

EOS Bodies - For Video / Re: IS on when filming on tripod?
« on: June 27, 2014, 02:38:59 PM »
While playing with a Tammy 150-600 last week at Steptoe Butte State Park I had to turn on the IS (or whatever Tamron calls it), even though it was mounted on a RRS TVC-33 w/ BH-55 tripod, because of the gusty wind!

Technical Support / Re: Monitor recommendations

If you can wait, the folks at Apple are past-due at bringing out a new monitor that will likely be a 4K Thunderbolt.

I'm looking to upgrade my iMac also. My crystal ball says September for new Apple iMac & monitor options...

Thanks guys, it looks like I'm going to keep my pre-order and be able to relax a bit after all...

Eldar, thanks for the reply. When your 50A (that started out to be "spectacular") decided to go "bananas," was it an easily observable change in behavior (maybe even visible on the camera's lcd)? I'm just wondering if I'm going to have to run a FoCal test every 2-days-or-whtever just to be sure that my copy is stable. I'm hoping that if it "passes" an initial test, and later starts to exhibit some banana-like tendencies that it will be obvious and won't require FoCal-testing or pixel-peeping...

12
I've been hanging-on every word of this thread as I sweat-over my own pre-ordered 50A... I really appreciate the way that all you guys have told of your experiences, good and bad, it is truly helpful. When I saw the posted FoCal results & graphs I had an idea...

Do you guys think that I could rely on testing a new 50A with FoCal as a way to insure that I get a good-focusing copy?

I'm going to risk the wrath of the forum-members here and do a blatant double-posting... Sorry, but I'm just afraid that it'll get lost in the other thread, and I think it's an important question that I haven't seen asked or answered yet...

I pre-ordered the new Canon 16-35 f/4 based on how everyone was drooling over the MTF charts. My question now is, does anyone know of a lens whose sharpness/resolution did not live up to its good looking MTF chart? I'm just considering optical performance here; not AF, build quality, or anything other than image quality.

My advice, in all seriousness, is don't. It will be a letdown. Tilt with the 17 is very difficult to achieve accurately with live view anyway as the gearing is far to coarse, a fraction of a turn, even the pressure of your finger on the knob, will move the plane of focus some distance at moderate J point distances.

As for having tilt lenses prior to Live View, this is true, but they were not 17mm ones and the wider the lens the more difficult the accurate adjustment.

Failing that make some basic J point measurements, and use a tilt table (Northlight has one for the 17mm), it will work well enough.

What PBD says is the sad truth... When I'm really lazy & try to hand-hold a tilted shot, the only hope I have is to stop the TS-E lens way down in the vain attempt to increase my margin-of-error by increasing the DOF.

Well... I really didn't want to contribute to the thread-hijacking, but I just can't help myself 'cause I truly do love my Lee filters...

You can hand-hold an ND grad for a few seconds, but not for the 30 seconds, 90 seconds, 120 second exposures needed for that.

Sure you can! That's why God created gaffer's tape (on the 8th-day I think it was...)! Honestly, I do it quite often, my tripod is liberally decorated with innumerable scraps of gaff-tape just for sticky situations like this... I have found that the vignetting-culprit is the massively thick 105mm CPL and even then only with the 16-35mm wider than about 22mm on a full frame. So at those times when it's worth the hassle, I will use a 4"x4" square CPL in the front-slot of the Lee filter holder, rotate it to taste, then tape the reverse ND-grad into place. Lastly, I'll add the Big Stopper behind in the other slot. If the exposure is short enough (or I don't have the patience to deal with tape) I'll just hand-hold the reverse ND-grad during the exposure. I hope that this sounds correct, I'm typing via the search-&-destroy method on my iPad...

Now, in an attempt to get the thread back on track...

My question now is, does anyone know of a lens whose sharpness/resolution did not live up to its good looking MTF chart?
