Digital SLR / DSLR Camera Question / DSLR Thread 2

i really need photoshop. lightroom is great but is just missing 2-3 tools i could really use (eraser, better dodge/burn, and a few random filters)
 
Frustrating. I appear to have an image somehow corrupted. It displays fine, I can edit it and everything, but when I attempt to export a jpeg (it's one of about 100 that I'm doing as a batch) Lightroom insta-punts my computer into hibernate mode, and I have to actually remove the battery to get it to boot back up.

Skipping that one picture and doing the rest of the export, but :wtf :rant :mad

Is it the entire batch process or do you know it's one specific image?
If so, can you identify which one is corrupted?
Open the image in another program such as GIMP, and Save-as, then Open with Lightroom?
 
I ran the whole batch minus the image it stopped on the first three times.

Worked fine.

Then I exported just that one by itself.

Also worked fine.

:facepalm

Whatever, I'm done now. Will figure it out if it happens again.
 
did a shoot of my brothers band. after using my d90 for a bit, pulled out my F4 to get a few film shots. man, that thing has an awesome viewfinder...
 
Going to send PS back, eventually get the entire sodding suite. So stupid - an extra $200 to upgrade EVERYTHING compared to buying just the standalone. How can this be good channelling of their R&D money? Not to mention, I'll be looking at other image editors more seriously now.
 
Lens review:

Decided to take the plunge and buy the 17-40mm L lens, and the 24-105 L this weekend...








...just kidding. Not that rich!

Alex very kindly lent me both his 24-105 AND his 17-40. Have to say, I thought the 17 was going to be 'too much' and was seriously considering getting the 20mm non-L lens soon. Now I'm rethinking.

The 16-35 would be really nice (F2.8 versus F4) but $1600 versus $750... *sigh*

And, now I need to borrow/rent the 24-70 to see if that is much of an improvement over the 24-105, which when at 24mm, has pretty horrific barrel distortion, I gotta say - see next.

First up, the 17-40 at 24mm:

Not PERFECT, but pretty darn close. Not put them up yet, but even at 17, it holds up, barrel-distortion wise - impressed.



Next up, and it's hard to describe quite how bad the barrel distortion is until you look through the viewfinder and move about. Alex, you probably don't see this that much with the crop sensor, but on FF, it's pretty obvious. Frankly, am surprised this is the 'kit' lens:

24_105_small.jpg



I put in little marks and you can see how far the distortion goes.

Now, you could legitimately argue that it isn't barrel distortion at all, the 'offset' parts of the line are closer, ergo they appear bent up, which is how we actually see things, but they did a fine job compensating for that with the 17-40, not so much with the 24-105. The 17-40 might be 'fake' but it sure makes buildings look prettier.

Convergence, yes (not a lot you can do about that except use a tilt-shift I guess) but no barrelling - this is at 17mm. Oh, and F4. Still pretty sharp :)

That said, the CA on the 17-40 was pretty bad at F4 in bright sunlight, see next:

17_40CAtest.jpg


Then again, that's a 100% crop - it IS noticeable as a pretty bad halo, but I was also asking a lot - F4 in bright sunlight (I was dicking with short DOF shots of flowers before taking this one) so you could argue it's an unrealistic edge-case. Stopping it down to F8 made it go away, and it wasn't a problem with less light and less contrasty edges - basically went away completely.

Conclusion is - might not get the 20mm non L, and might save my pennies for the 17-40.

Will try the 24-70 and see how the barrel distortion is on that before I pull the trigger - anyone got one I can borrow please? :)

For now the 85 F1.8 might be my go-to in the studio, with my FF 50 and 28-105 zoomed in, where it performs OK.

And for now, tempted to get the Sigma 18-55, which is on sale for $199 at BHPhoto (!). Just so I can take landscapes. It reviews really well, so... that I can absorb in a month, especially if I ditch it for $150 after a few months, $750, not so much.

Thanks for letting me use your sexy gear Alex! I do have to say tho, the QUALITY of image from the 24-105 was really nice when zoomed in just a tiny bit... but not sure I could live with that distortion wide-open, at least on a FF body.

Glad you liked the lenses... sort of. :teeth Since my 40D has a 1.6 crop I don't have to worry about some of the stuff you guys do with a FF camera. When I eventually pick up a 5D or another FF body, chances are I will also look at some of the L prime lenses, but for now a 40D with a good set of L zoom lenses seems to be a decent compromise. The quality may not be quite up to par with a FF body and prime lenses but I'm taking A LOT more pics with the convenience of zoom lenses. It's a trade-off I can live with for now.

btw, one of the deciding factors for me picking up the 24-105mm f4 vs the 24-70mm f2.8 was weight. A DSLR is already a big brick to carry around and some of the really nice lenses I drool over weigh A TON! Whether I'm at the races or with the kids or out camping, if the equipment weighs too much and I leave it at home, I won't take ANY pictures... so I would rather compromise quality just a bit and take the pics with a zoom lens than leave the camera at home. ymmv...

Hey Alex, don't get me wrong, apart from that cyanic aberration on the shirt edge, when shooting in bright sunlight, at F4... which is a bit silly anyway, I *really* like the 17-40 - much more than I thought I would. Although I have to say I found myself at 17 almost all the time, but it was nice to be able to zip to 40mm to get almost-neutral shots.

I was just surprised by how much barrel distortion there was on the more expensive 24-105, more than my $200 28-105.

BUT, only slightly zoomed it, in pretty much went away, and there was no appreciable CA on it at all. And as for image quality, I'd say it was still slightly better than my 85mm FF non-L.

I'm just curious to see if the 24-70 has the same barrel distortion wide open - if it does, make me wonder why I'd get that lens at all, as half the point is to have a nice studio lens, the other is to have a great walkabout lens that will do fairly wide shots, and still some zoom at the other end. I can see why you like the 24-105 for the same reason I like my 28-105 - it's VERY flexible and can be used for 90% of the time.

And even in the studio, especially when you're grovelling on the floor to get the shoot, having a zoom is easier than either moving back and forth, or continuously swapping lenses :|

So, still dunno. I just need to win the lottery and have both.

Anyway, when do you want them back? I texted you, but left my phone at home like a dumbass...

OH, and THANK YOU VERY MUCH! For lending them to me, and trusting me :)
 
the nikon 24-70 has some distortion. i think any zoom lens will really.

edit: meant to say 24-70 not 70-200

You're welcome... and of course I trust you, if you buggered up the lenses we both know I could snap you in two like a twig! :rofl :twofinger

Keep them for this weekend and just come over sometime next week. I actually haven't even used the 24-105 yet, I only picked it up a couple of days before I handed it to you. Have fun with the lenses, I'm sure some day I'll need your advice and expertise 'cause let's face it, I'm just a newbie with cool toys, I still don't know wtf I'm doing with a DSLR... thank God for Auto program when I get really lost and confused with all those damn buttons! :laughing
 
Just picked up a Nikkor 10-24 for my backpacking trip this weekend. hopefully I'll be able to get some good landscapes. Been quite a while since I've done any. And yes, I got the insurance this time. :)

Sweet! Thanks man :thumbup

24-105 is in my briefcase ready for tomorrow - IM and/or text me your work address and I'll drop in, tho I usually don't hit the south bay until 7.20ish most days...

Doug and I are planning to hit Castle Rock at sun-up on Saturday. Euch... Doug's bringing his 4x5, and using his Lumix as a very fancy light-meter for it, lol!
 
Happy birthday to me! :teeth

Still trying to warm up to it's controls and get used to it's weight. Me Likey!

Very jealous of your destinations guys, but at least I'm headed to Oregon myself.
 
Normally that would warrant an "I hate you", but Sunday morning I'm going to be next to a lake in the Sierras at about 10,500' watching it come up over the opposite valley. :)

Don't worry, I'm probably going to hate myself at 4.45 when the alarm goes off...

Charles, congrats :thumbup
 
I sent my mom off to london with my nikon. hopefully she figures out how to use it, and comes back with some decent photos.
