  1. <p>I just heard about Alzo for the first time today. Can anyone tell me about good/bad experiences they've had with this company or anything they know about it? Haven't been able to find much online in the way of reviews other than what they say their customers say.</p>
  2. <p>Thanks, Andrew. Your post answered some questions. After all this time worried about custom white balance only to discover it doesn't matter when shooting raw. Who knew? But I'm very happy to finally learn that :)</p>
  3. <p>I shoot raw. Just read on the Xrite colorchecker site that you don't need to use the white card when shooting RAW, if I understand correctly. You only use that white card when shooting JPG or TIFF. A photo of the white chips included on the color grid is used to set white balance after the photos are transferred to the computer when shooting RAW and a photo of the white card is used to set white balance when JPG and TIFF photos are viewed on the computer. So maybe a custom in-camera white balance is never needed when using the colorchecker passport? Not certain I'm 100% correct though.</p>
  4. <p>I do outdoor portraits with a speedlight and softbox plus Colorchecker Passport. I know how to set a custom white balance in my camera but there are a couple of things I'm confused about. </p> <p>I often put a subject in open shade and usually have a brighter area in the background where there is light coming through the trees and lighting up leaves and a grassy area behind the subject. After I balance my flash on the subject to the ambient light, I set the white balance by having my subject hold the white card part of the Colorchecker Passport. It's so small, I have to take my camera off the tripod an approach the white card. I photograph it using the same flash setting that will be used when I photograph my subject. </p> <p>1st question: when photographing the white card, I usually have to change the shutter speed or else the flash blows out part of the white card. (I'm puzzled by this since the flash does not blow out on my subject.) I've now got one exposure for my scene and subject with flash, and a different exposure for the white card. Is that ok, or will the different exposure for the white card make the resulting custom white balance invalid for the settings I plan to use to photograph my subject?</p> <p>2nd question: my understanding is that when photographing a white card for a custom white balance, the card should fill the frame. But there's no way I can get that small white card in the Colorchecker Passport to fill the frame. That means I'm creating a custom white balance with the white card plus whatever else happened to around the edges of the white card when I photographed it. Does that other stuff affect my custom white balance? If so, (this is rhetorical) why is the white card in the Colorchecker Passport so small if it cannot reasonably be used to create a custom white balance?</p> <p>3rd question: Similar issue when photographing the color squares/grid of the Colorchecker Passport. I have to take the camera off the tripod to get close enough to the passport to photograph it and in doing so, I generally have to change my shutter speed to prevent parts of the passport from blowing out when photographed using the same flash setting that will be used to photograph my subject. Is it ok that the exposure used to photograph the Colorchecker Passport is different than the final exposure of the subject?</p> <p>Hopefully someone uses the Colorchecker Passport and outdoor flash and has some answers.</p>
  5. <p>First: In Photoshop I have the View > Gamut warning turned on so I can see the out of gamut areas represented by the gray overlay Photoshop puts on them. There is a large out-of-gamut gray overlay on a red dress. Next I decided to create a mask that only includes the out-of-gamut colors. The problem is, when I use the Select > Color Range command and choose Out of Gamut from the drop down list, the resulting selection does not include the red beneath the largest area of gray overlay. In other words, Photoshop is telling me that yes, there is a significant out-of-gamut area but no, it cannot be selected. It does select some other tiny areas in the image that are out of gamut but not the largest area that I need the most. I tried viewing the selection as a mask and as marching ants and neither included the reds I'm after. How do I get Photoshop to select <em>all</em> the colors it says are out-of-gamut and not just some of them?</p> <p>Second: I obtained a color profile from the print lab where the images will be printed and installed it at View > Proof Setup > Custom. Then I hit Ctrl Y to toggle Proof Colors on and off to see the color shift that will occur when the image is printed. That part worked just fine. But when I turned on View > Gamut Warning, I get a gray overlay gamut warning on the reds that remains regardless of whether Proof Colors is on or off. Shouldn't the gray gamut warning overlay disappear when Proof Colors is turned on since the photo lab color profile has (in theory) brought the colors into the color space used by the photo lab's printer? Why, after the printer profile shifts the image colors into the color space of the printer, would there be any out-of-gamut colors?</p>
  6. <p>I was harassed once for taking a photo of an old door from the parking lot across the street from the building with the door. The guard said I was trespassing on private property. I looked down, saw where I was standing, and literally took one small step which put me onto the public street. I couldn't believe anyone could be so petty about me being a few inches off the public street. There wasn't a no trespassing sign. If it's that important, why not put up a fence? </p> <p>I've also been harassed 2 times on Mare Island for simply walking my dog.</p> <p>The first time was a couple of months ago when I was walking on what I thought was a public street at Touro University. The security guard pulled up in a Universal Protection truck and said Touro doesn't allow dogs so I immediately left.</p> <p>Afterwards I sent the city 2 emails about 2 weeks apart to different email addresses asking whether or not the streets at Touro were public or private. A simple question, no? I got zero response. Yesterday I visited the city public works department in person to ask my question: are the streets at Touro public or private? I was told they are definitely public streets maintained by the city but that the main street, (Moises, I assume), will become a private street in the future but only after a lot of public notice is given out about the change. I then asked if Touro has a legal right to tell people they cannot walk their dog on a public street or set any other rules for accessing public streets. The person I spoke to said they'd research it and get back to me.</p> <p>In the meantime, today I was stopped while walking on Nimitz Ave and told by a very angry security guard that said I shouldn't be walking my dog there because it's a "construction zone". I slowly turned 360 degrees and could see no evidence of any construction. (At the moment, there is a section of Nimitz is not accessible to the public due to earthquake damage but I was well outside that section.) When tried to ask what city ordinance I was violating by being on the publicly accessible part of a public street and why a construction zone wasn't marked as such, he just kept angrily talking over me and would not answer questions. He seemed strangely upset, way out of proportion to the circumstances, so I just walked on down Nimitz to get away from him. Never had anyone harass me for walking on Nimitz before in all the many years I've walked down that street. Oddly, the security guard wasn't stopping any cars that were driving on Nimitz, just me, the pedestrian with a dog.</p> <p>I sent an email to the person I spoke to in person yesterday at the city asking her to include Nimitz on the list of streets where, similar to the streets at Touro, you can't walk with or without a dog.</p> <p>Later today, I got a call from someone at the city in response to my email and inquiry from yesterday. This person told me the exact opposite of what I was told in person at the public works department. He said all the streets at Touro are private and all street maintenance and repairs are done by Touro. So I'm back to square one and have no idea if those streets are public or private. Is there such thing as sending a Freedom of Information Act request to a city? I think that's the only way I'll get my questions answered.</p> <p>In regards to being stopped by the security guard today, the person on the phone was no help there either. I kept asking under what ordinance pedestrians are not allowed to walk on the publicly accessible section of Nimitz that cars are allowed to drive on, but the person on the phone kept conflating my question with earthquake damage and saying the security guards are just trying to keep everyone safe by preventing them from walking in areas where masonry may fall and injure them. I repeatedly tried to point out my question was unrelated to earthquake damage. Either pedestrians are allowed to walk on Nimitz or they aren't. Which is it? And if not, what's the governing ordinance? Couldn't get an answer. He told me to contact Universal, the very people who are violating my civil rights. The one helpful thing piece of information I got from the phone call is that Lennar hired Universal Protection Services, not the city.</p> <p>One other weird incident that I witnessed. A delivery van apparently broke down on Azuar and was off to the side of the road. You know how companies with fleets of vehicles often have their own repair truck that goes out when a fleet vehicle breaks down? There was a truck like that behind the broken down vehicle. I could see that it was carrying all sorts of tools. There were 2 guys who where clearly working on the broken down van. When you've got a business that uses delivery vans, you can't afford to have one broken down by the side of the road. I saw a Universal Protection truck pass them, then pull a U turn then park illegally (as opposed to the delivery van and truck which were parked legally). The security guard got out and was making a big show of quickly walking all around them taking pictures or video of the 2 guys and the 2 vehicles. He'd walk up very close and take photos then back away and take more photos. Back and forth, around and around he went. He looked totally deranged.</p> <p>I think this is one of those situations where the city hopes anyone with a complaint will simply give up and go away. Until the city gets sued for civil rights violations for not allowing citizens to walk or ride bikes or take photos on public streets without being harassed by private security guards who are just citizens like the rest of us and have zero authority to tell us to leave public areas, the city won't bother to address the situation. Maybe it will take some sort of restraining order.</p> <p>Perhaps an organized civil action might bring attention to the issue, like dozens of people walking their dogs on Nimitz all at the same time carrying signs demanding the right not to be harassed on public property. Or a large number of photographers going from one public area to another taking photos and video, especially of the security guard(s) that show up to harass them for being on public property.</p>
