As much as I love Aperture, i have discovered that my blur brush tool just doesn't work.  Even if I set the strength at one (highest) nothing happens.

 

All the other brushes (such as dodge and burn) work fine.

 

My Aperture software is up to date.  I have read some other posts on this but didn't see an answer.  Someone suggested that the effect is just very faint, but that can't be right.  Apple's own sample image of the blur brush tool shows much stronger correction.

 

Thanks for any suggestions!

    Make sure the brush range is set to "All".  (The brush range is set from the Brush HUD Action Menu (a/k/a "the gear").

     

    And just to make sure, you are using _both_ the HUD slider and the Brick slider?

    Thank you.  I understand the blur brush better and the need to check "the gear" settings.  However, I think the blur effect is just more limited than I anticipated.  I think I can get what I need by stepping up to the retouch brush when the the blur brush isn't providing a strong enough effect.  Thanks again.

    Yes, it's a very limited tool in both application and results, nothing like the blurring you can do in a pixel editor.  This is my habit:  I crank up the intensity in the brick all the way up and apply it at 75% in the tool.   I don't want to see it as it will eventually look while applying it, I need to really see where it is going.   Then I lower the brick's value to where it works way down.   But Aperture's blur alone generally won't do what I need in a blur so during those time when I must stay in Aperture and not hand off a TIFF to an external editor (really what you need to do for good results here) I add a brick of skin smoothing and one of noise reduction but use them as a blur aid rather than their intended purpose, and several bricks at low settings together rather than one at a higher one works better.

    Note that while the slider stops at "50", you can use the Value Slider to go all the way to 100%.

     

    I don't know your needs, but a the Blur brush at Strength=1 and Amount=100 is not -- afaik -- in any normal way "limited in application and results".

    Another example:

    The Blur-brush set to 100% made the second flag vanish completely.

    For good measure I brushed three times, but that does not add much to the initial result.

    "Note that while the slider stops at "50", you can use the Value Slider to go all the way to 100%.

    It's limited in that it's only actually a single power of blur which you can brush on in varying intensities and then raise and lower the result to blend to taste.  These two intensities are the same parameter, just the amount of the preset blur you see.  In most pixel editors a "blur more" is not just the same blur raised higher but one that blurs further than the standard blur filter.

     

    It would be useful to have at least a gaussain blur with the radius parameter that most have, since a 2 pixel blur at intensity 7 is very different from a 9 pixel blur at intensity 3.  Just having the option of raising and lowering the amount of blend of only a single power of blur is limiting, as the intensity of the brush-on is the same as the intensity of the instensity slider.  Just how much of the non-variable blur you want to see.

     

    I would love to have at least some of the other common blur options Radial blur is especially useful.  It's probably my most used blur,  as is a smart blur that detects and avoids edges.  But I would be happy with at least some parameter on the blur, such as pixel width.  Or even a choice of 2 pixel or 8 pixel width, similar to a "blur more", which would extend the blur further out.   Very different results.  Right now it's kind of like "here's a single strength generic blur.  Blend to taste."  

     

    Just means a lot of TIFF round tripping, especially in order to get precise, clean edge control without spending an inordinate amount of time on it..

     

      Don't get me wrong, I love Aperture, I get it done to my satisfaction, but Aperture itself only gets me 75% there.

    I want to clarify my badly worded post.   The strength of the brush slider does affect the distance of the blur while the intensity is the amount blended, which is not the same.  However the way the strength is implemented is a bit too much like using sidewalk chalk when you want to use a felt tip pen, not giving enough useful effect, IMO, aside from "subtle or strong vanilla blur"   The strength goes from subtle to an "averaged" blur without, to me, a good strategic in between stages.   It lacks what other blur filter styles can give you, regardless of the strength or blend.

     

       When I work in pixel editors I rarely choose simple "blur" on a section because I have gotten used to the different results that a gaussian or radial (or motion) blur will give.   I keep wishing that Aperture had such other blurs to supplement it, as I would use them.

    Good points -- thanks for the clarification.  Since you are replying to, among others, me, I feel  I should respond even though I don't have much to add. I am traveling and will respond in full later in the week.  Sorry for the empty place-holder, but I didn't want you to think your posts were unappreciated.

    :  )  No worries, Kirby.  I did post and hit send without enough care.  My bad.

     

    I do like Aperture more than any other DAM and use it daily, but there are aspects of the filters which I would love to see improvements in the next version so that I would be less inclined to round-trip to TIFF with an external editor so much, and blur is one.

     

    Good travels  :  )
