@Terry,

I use star ratings indeed, but this still is a rating or collection/selection 
within a certain folder on my harddisk. It would be great if I can mix ‘m up. 
To give an idea: I have images from several vacations that I’m going to split 
up to new selections. The original folders are based on the vacations, the new 
selections on categories like ‘architecture’ and ‘nature/landscapes’. Those 
categories aren’t limited to the original folders anymore.

 

About the histograms: I don’t rely on them heavily either and (fortunately?) I 
don’t have an Adobe background. Well, except for the use of Photoshop Elements. 
I would indeed like to see some examples of the different histograms with 
explanation.

And is there a short and clear explanation on the differences of these 
histograms?

 

@Marc,
Thanks for your answer. This might actually work for question 1.

 

@all: I’m still looking for an option that helps me show a selection. Example: 
I have a selection of 20 photos in – say – my category ‘Architecture’. All 
photos are good enough, the have enough stars or the right color given to them. 
Now I want to minimize the selection to a series of 12. Therefore I want to try 
several combinations without having to tag (and detag) them all the time. I 
know that Lightroom has the option to select images and press some button to 
see the selection. That makes it easy to quickly decide what works. I’d really 
like something like this. I could really use that!

 

Hartelijke groet,

Hieke van Hoogdalem

Dag Hieke,

 

For your folders question: it is possible to tag with subdivisions. I do that 
for my work for the photo art school versus my personal work. The tags may look 
like this:

*       school|cityscapes
*       school|portraits
*       projects|myfamily
*       projects|street

You can assign multiple tags to a single picture. For instance a portrait of my 
son my appear under school|portraits and projects|myfamily. Or the same picture 
may appear in school|cityscapes and projects|street.

Bruce Williams has some youtube video’s on the use of the darktable database 
and the lighttable. Some of them may be a bit confusing at this point in time 
because explained for a former version. But the tagging works as he explains. 
You may want to have a look at these.

 

Hope this helps,

met vriendelijke groet,

Marc.

Hi Hartelijke groet,

            someone else may come with a better answer for your question. 
Lightroom uses collections which can be very convenient. However, a possible 
easy solution for you is to give the images a color or star rating so that you 
can easily filter the view to see a selection of images. 

 

As for histograms, I was teaching my students about this last night. The answer 
I always give is to use either log or linear based upon which one gives the 
best information. There is no hard and fast rule to which one is best. Many 
average scenes may look great with linear, but with some scenes where there are 
fewer bright or dark pixels these may be not obvious on a linear histogram but 
become very obvious on a log histogram. Just switch between the two and decide 
which is best for the individual image. I would also like to point out that 
coming from an Adobe background for image editing I relied heavily upon 
histograms for editing. Having watched numerous videos by the Aurelien who is 
the developer of many Darktable modules I have come to view over dependence on 
the histogram as painting by numbers. The look is the most important bit when 
editing. When using the linear histogram you adjusted the image until it looked 
good and there was no obvious clipping. That is great. However, the log 
histogram detected a few extreme pixels which were clipped. These may have been 
a small number of  black or white pixels that were at the extremes and not 
significant to the image. The log display histogram overstates their importance 
for this single image. If you want to see some examples of what I mean, just 
ask.

Hi y’all,

 

I have 3 questions:

 

1.      Is there a possibility to make folders in Darktable for subselections 
of your work? Say I’m working on a series and I’m trying different 
combinations, it would be handy if I had the option to create/save those series 
somewhere, from within Darktable. I hear Lightroom has something like that and 
I figure it’s very helpful. >> [1a] It would also be helpful if the order can 
be changed, to see what order works best for that selection.
2.      Can I select more than 2 pictures and show them as a series in a pop-up 
or different screen? Like culling, but for more images. >> [2a: Again... It 
would also be helpful if the order can be changed, to see what order works best 
for that selection..]
3.      I discovered that the histogram box shows 2 different kinds of 
histograms. I don’t understand the difference. (Logarithmic/lineair.) What’s 
the best option for newbies to histograms? I was looking at an image that 
seemed great, but the histo was way clipped. Then I discoverd the lineair 
version and nothing was clipped at al. Of course I look at the picture for the 
results, but I also want to work with the histogram more. I understand the 
basic idea, but I don’t know for wich version that goes :-)

 

Oh and culling doesn’t work well. Sometimes it’s okay, sometimes I see another 
selection being enlarged. In that case 1 is from my selection and the other is 
the one next to it, but something I selected. Since I’ll be working on a 
Macbook Air next week I’m not diving into this too much now. At this point I’m 
still working on a Windows 10 64 bit machine, don’t know if that’s helpful info.

 

Hartelijke groet,

Hieke van Hoogdalem
