I prefer Lower antelope. The chief and his sister do competing tours, one goes up the other down the canyon in fairly large groups. Very hard to get non obstructed shots. The 'sun rays' are intensified when the guide throws sand up in the air. As suggested above try other less populated canyons.

In previous version of Photoshop, within the Adobe/Photoshop folder there was an executable (.exe) file for Photoshop. I do not see one in the 2021 version. I used it for a redirect for a pc program, Faststone.
Take a look at Faststone as an image organizer with limited editing capability..

While out shooting with XT-30, error message 'file no full' appears on screen. The XT-30 was repaired recently and the folder number was set to 999 by Fuji. A thousand shots later and the shoot is over. Formatted another card, a few shots left, but the real problem is the folder 999 issue. The manual does not explain how to reset, Utube videos no help. Anyone know how to reset the folder back to 001 on XT-30, 20, and 10??

Now when I plug my LG 7Q thin to pc, it just shows 'Folder Empty'. So the phone pictures are not available. Is it an issue with the LG gallery or have they been transferred to a google photo ap?? Previously I could just drag and drop the images from the LG as stated in previous posts..

I use a DROBO raid systems for file back up. HDD's with larger capacity can be installed to increase the overall capacity of the DROBO unit. The removed HDD's have been formatted by the DROBO system to an unrecognizable format by a PC. I put the removed HDD's into a docking unit with the intent of reformatting them to a standard format. As noted the PC, WIN 7 does not 'see' the drive. I have put other (non Drobo) HDD's into the same docking station and their file structure is recognized.

Calling Drobo support provided no help!!!
Any ideas???

What is the difference between exposure and brightness in general and how does that apply to the histogram??


How do the dark, shadow, highlights, and white sliders relate to the tone curve? They must me overlap some how. Moving the sliders in LR does not effect the visual tone curve. So the follow up is, do the tone curve adjustments effect the histogram.

I understand the 256 'bin' limitation on the horizontal axis, but what is a tone??

Enough for now.. Being a retired engineer I can not just accept qualitative mumbo jumbo. Obviously there are algorithms for each of these terms!!

There are numerous terms that must in some way relate to the histogram..

Saturation - The definitions I read are pretty vague, color purity,no saturation >> shades of gray, etc. Is saturation based on one of the 256 tone levels with only one color present.?? I do not grasp the definition in a quantitative sense.

Hue - Basically the same question.

Luminance - This one seems a bit more intuitive, but

When it comes to adjusting blacks, shadows, highlights and whites in Camera Raw or LR, it is apparent that portions of the histogram are moved left and right. OK with that.

What is the correct term for the histogram horizontal axis luminance, tone levels, brightness????

I am trying to grasp the detailed creation of histograms..

I think this to be correct...
A sensor has x pixels cover with a Bayer array, ie each pixel has a red, green or blue filter and has a single linear luminance level associated with it and recorded as RAW data.

The camera processor creates an RGB value for each pixel using some sort of nearest neighbor algorithm producing the JPG thumbnail image on the LCD screen.

Now the questions
Is the gray histogram calculated from the luminance levels from the JPG values for each pixel??

How are the RGB histograms calculated?? Is it from the raw data of each pixel or is it calculated from the RGB values created for each pixel????

I have B-W linear and circular polarizing filters that have bound up/hard to dial. Anything work to free them up?
