Photoshop :: Getting Measurement Log Error?

Jun 12, 2013

I'm recording measurements (gray value) in a selection, using the "record measurement" in the measurement log panel. I need to repeat this over thousands of images. I've written an action that opens the images one by one (batch process), records the measurement and closes them.

However, after exactly 700 measurements, Photoshop stops and says that it cannot record this measurement. I've tried this with CS4 and CS5 (extended) as well, and I get the same result. why Photoshop measurement log has this "700 entry" limit?

Photoshop :: Light Intensity Measurement

Jan 17, 2009

way to quantitatively measure the level of light intensity in different conditions. I know there are light intensity gauges that measure lumens and fc's but I was wondering if there is a way to measure the brightness of an image using photoshop?

So far I have noticed that there is a way to change basically everything about an image but I haven't found anything that gives me information about the picture itself besides its size and resolution.

Does anybody know how to measure light intensity or brightness of an image?

Photoshop :: Analysis Measurement Gray Values Incorrect?

Jun 23, 2013

I'm trying to use the Image Analysis functionality of PS CS6 to obtain brightness levels from an image.
 
To test the "Gray Value" measurment, I've created 11 patches from 0%-100% in 10% increments. I used the fill tool (Shift-F5) and specified values using H=0, S=0, B=<percentage_value (0-100)>.
 
The respective RGB components of the generated patches are exactly as expected (255*percentage_value).
 
The measurements obtained through "Record Measurement", however, do not agree, with the exception of the 0% and 100% extremes, which are reported with 0 and 255, respectively.
 
Inbetween, there is disagreement which rises from 0 @ 0% to the highest (5 @ 50%) to then decrease again to 0 @ 100%.
 
Here is the series by which the reported Gray Values are too low (from 0% - 100%): 0, 3, 3, 4 4, 5, 3, 3, 2, 1, 0.
 
How come?
 
I've tried removing colour profiles (to exclude gamma encoding issues) and using different colour spaces and/or models, with no change in behaviour.
 
All my patches are pure gray so there shouldn't be any problem with unexpected colour weighting.
 
One funny observation I've made is that even though the patches are a 100% homogenous, PS reports different miminum and maximum values. For instance for the 50% brightness patch (RGB triples of 128, 128, 128), the report is MinVal=123, MaxVal=124, MeanVal=123.934809.
 
Clearly, the value for all three aspects should be the same, and I expect the value to be 128.
 
I'm using PS CS6, Version: 13.0.1 (13.0.1 20120808.r.519 2012/08/08:21:00:00) x32, on Win 7.

Photoshop :: CS4 Extended (custom) Measurement Ruler Tool - For Curves / Radius?

Jan 17, 2013

I have created a custom measurement tool to measure distances (captured from sattelite imagery, and using the distance key as the guide) and it works great. However, I would like to be able to use the same tool to measure curves/radiuses. Say for instance a mountain road. I know the scale of the photo, and can measure any straight (line) angle, but can I do the same for a curve or radius using the same scale?

Photoshop :: Exact Copy-paste

Dec 5, 2008

I have two png images with embedded alpha channel.

It is wall (pic1), and it is wall's shadow(pic2).

They positioned exactly as they should, but on different pics.

If I select all area with wall picture (pic1), and copy past it to shadow picture(pic2) - wall appears at different, then original, location.

So, basically, how can I copy/past wall into shadow picture, with the same position, as wall has on it own picture?
