See the adjustments in real time to selected pictures

[NNN636763483034247707]

Hi… I realized that if you press the “A” button in any tool (auto) while you have several pictures selected, it is automatically applied to all of them at once (you can see the effect in real time). But if I move any slider, the effect applies only to the principal variant, and I need to copy and paste the adjustment to the rest.
Is there any way to see in real time the effect of one single slider (let’s say contrast) to all the selected pictures at the same time? I would love that behaviour (at is it with “Auto” button) and I don’t know the rationale behind this. Many thanks!!!

No it doesn't work like that. I think the rationale is that it would require too much of a processing overhead.

Many thanks... I think it is the same overhead than do copy and paste after that, but one extra step for the user. I we already can mark/unmark the "Edit selected variants" option, I dont see the reason to force the user to do the extra step.

On top on that... as I said... the auto button of each tool, doesnt work that way and you can see the effect in real time to all variants.

There might be another reason, or it is a bug. I come from Lightroom and find this a big disadvantage

[Ian3]

It's not a bug - that is definitely by design. And there may be an overhead impact. To show all the images adjusting in real time, is to quite the same as copying the adjustments to all the images. After all, if you had say 100 images, you would notice a bit of a lag if they adjusted as you moved the sliders which would not be noticeable as the copied adjustments rippled through all the images.

Anything that requires some simple calculation - set a colour tag, set a rating, add a keyword, change exposure by a specific value (for all images) using a keyboard short cut - carries minimal overhead and can be applied directly to multiple images. In effect the visualisation of styles in thumbnails and previews seems to work the same way.

When you move slider around there are, potentially, multiple adjustment points for every short distance that the cursor moves before you settle on a value. For some tools the recalculation required for a single image (especially for a large original file ) could require significant processing power. AND you may several hundred or even several thousand variants selected. So have visual interaction with so many images would probably not be advisable if you hoped for a good on screen response.

If you modify one image to be the way you want it the processing overhead is much less and the copy and paste process can then be done afterwards as a background batch process that is working with a fixed set of known values rather than a slider crossing and re-crossing the same value change points many times even for a single slider on a single tool, as Ian3 has already pointed out.


HTH.

Many thanks both.
I really understand your rationale and it makes totally sense to me.
Taking that as a very good point, I would suggest then to PhaseOne: Don’t apply in real time the changes to all the selected pictures if the mouse button is down while moving the slider, but once you release the button, then apply to all of them (if the “edit all variants is checked”). Or at least, include that option in “preferences”. The extra time needed to copy and paste adjustments is making me crazy all the time, and I know other users coming from lightroom that find this annoying as well.

[Ian3]

If you want to make a suggestion to Phase One, don't make it here! We are only fellow users. You can suggest enhancements to the software through the Support Case system.

...I would suggest then to PhaseOne: Don’t apply...

Yes, you should indeed file your request with Phase One. Telling us, your fellow users, what you want, will most likely not lead to changes in C1.

Also ask all those former LR users now annoyed by C1 to also file a request like your own. Many request are known to have more impact than just a few requests. One day C1 may even become so LR-like that former LR-user may regain their LR-annoyance

Back in LR V1 days I was impressed by the instant response of LR to a change compared to another RAW developer/Editor which was somewhat more like C1 (although I did not have any experience with using C1 at the time I discovered the similarity later).

LR took almost no time to display a changed image but the other program clearly took longer (when attempting to apply a similar set of regular adjustments that both applications offered.)

Many noticed this.

However for some reason LR, though 'done', did not allow one to resume editing for a short period after it had finished. That seemed strange.

So I ran some timings and discovered that both applications took about the same time (around 3 seconds +/- .1 and an adjustment time allowance) from hitting the key to start the process to freeing up the image ready for the next activity. So the apparent speed of LR was, for practical use, an illusion. They were more or less equal.

Looking very carefully at the screens one could see that the 'slow' application took the instruction and presented almost nothing on screen until the end of the 3 seconds when it wrote the new version of file to screen. LR, on the other hand, made significant changes to the screen right at the start and then rippled around tidying up the details. (As I recall these were jpg files being tested at the time. Might have been some TIFFs too.)

I found it interesting to observe the different approaches to delivering perceived performance. It would be interesting to know if the same approach applies today.

Edited to correct some typos that made things difficult to read.

If you use keyboard shortcuts to make your adjustments, instead of the mouse to move a slider, it will apply the adjustment in real time to all of the images you have selected. For example if you have ten images selected and press 'Alt' + '+', the exposure value will move +.1 from their current values on all ten images, press 'Alt" + '-' and it will lower the exposure -.1 for all ten images.

Most adjustments can be assigned a keyboard shortcut if they do not already have them.

Indeed,

This is in line with a "fixed value" adjustment - like setting a rating or a colour tag.

I'm not quite certain what you're referencing, keyboard shortcuts is the way to simultaneously change adjustments of several images in real time as opposed to copy/paste, which is what the OP was looking to do, no?

[Ian3]

I think the point is that if you just, say, add +1 EV simultaneously to several images that is quite a different thing to gradually dragging the slider up to +1 EV and expecting all the selected images to brighten gradually as you do so.

Exactly.

Using a slider the system has to be programmed to determine when to make a change. Is the slider still moving? Has a value point been crossed?

So depending on how one uses the slider there could be tens or perhaps hundreds of "change value" point generated every second. With a large number of images selected it is quite likely that the system would not be able to keep up with all the changes in real time and aborting a change queue (or multiple queues) in progress would simply be messy and potentially error prone and very unlikely that the system could keep up with the levels of activity.

By comparison a simple instruction to change a single value in a single tool is more likely to be deliverable.

[cdc]

Oh I see.

For what its worth when I use keyboard short cuts and just hold down the keys its not all that different than sliding the sliders as far as speed and gradual changes on the screen goes, and all of the selected images in the viewer change in real time though the images in the browser are a second or two delayed. Seems like a decent alternative to achieve what the OP was speaking to, no?
