Business of Photography/Videography / SXSW Volunteer Call
« on: June 16, 2014, 10:05:28 AM »
Has anyone here ever worked the SXSW volunteer call?  If so what do they do with the photos and do you surrender your rights to the photos as a part of the deal?

Speedlites, Printers, Accessories / PIXMA PRO-100 with Rag Paper Results
« on: September 02, 2013, 11:57:03 AM »
In the past I have had issues with Canon Printers using dye based inks giving very soft results on Moab Entrada Rag papers.  I was wondering if anyone out there has used the Pro-100 with any of the 2 sided Rag Papers.
Now that they are on special I am thinking about getting one.

Here are just two examples.
I replaced it with a Zeiss and the issue was resolved.

Lenses / Promaster UV filter quality or lack of it.
« on: February 15, 2013, 01:46:40 AM »
Today I purchased a Promaster UV filter for my Canon EF 70-300mm f/4-5.6L IS USM.
After taking about 70 or 80 shots with it at various distances and settings I have decided that the filter degrades the sharpness of the photos to an unusable level.
Is it just hit and miss with these filters or are they consistently poor?  I paid about $36 for the unit.
With the lens in place the camera will auto focus but the image is just severely degraded.  Manual focusing wont' resolve the issue and there isn't enough f-stop in the work to make this filter sharp.
If Promaster wont' cut it then what brand should I be looking at?

EOS Bodies - For Stills / Re: Upgrading from Rebel XT
« on: February 11, 2013, 03:41:47 PM »
I upgraded from an XTi to a 7D and initially I was disappointed.  I totally lost the ability to take a sharp photo.
I have an EF 100 2.8 Macro which has given me good service and immediatly I noticed that pictures weren't as sharp and when I mentioned to the rep at Precision in Austin that the 7D  has never given as sharp of photos as the XTi they just dismissed it as user error and recomended to stop down.  I also have an EF 55 to 250 which gave good results on th XTi but didn't seem as good on the 7D.  Once again the reps dismissed it as user error and also stated that the lens wasn't good enough for the 7D.  So I bought a 70-300 L for the 7D and right off the bat it looked soft.  The first time I used it light was poor and the subject was back lite so I just figured it was a low light issue but after going back out 2 more times I started to wonder if I had gotten a skunky lens.  Until I tested the lens in the Rebel.  It wasn't the lens it was the camera.
Now some guys say you shouldn't look at your pictures using 100% magnification.  But I am one of those guys who can never get close enough to the subject.  So I crop the hell out of my pictures.  One reason I upgraded was to have a higher resolution photo I could crop down more if needed.   Some guys say they never crop down and that croping is just a cover up for bad photography but I am not going to throw away a great picture just because I couldn't get in close.  I am going to crop it down and sell it or frame it.  If some one buys my picture on Micro Stock then they may want to blow it up and it needs to be sharp.
Long story short the issue was in the Micro Focus adjustment.  After being blown off at the shop I researched the internet and found a lot of other folks with the same issue with the 7D.  The issue seems endemic to the 7D.  Or at least to certain batches of 7Ds.  The good news is, you can easily fix it using the Micro Focus adjustment feature built into the camera.  So just be prepaired to go to work in your house or your back yard to get the camera sharp.  I have 3 lenses and they all needed around +10 to +15 adjustment.  I bought my 7D as a refurb and I can see why the first guy who bought it kicked it back..
