Selecting subject vs. background when extracting with Refine Edge?
When extracting a subject from one image to another using the Quick Selection Tool and Refine Edge:
1. When is it better to make a selection of the background, make a layer maks of it, invert it, load the mask and use Refine Edge VS. just making a selection of the subject and using Refine Edge?
Thanks!
You would do it that way when the object being extracted is on a white background. You would place the replacement background on top of that image. Set the background replacement layer's blending mode to multiply for the lower white background will not effect anything on the replacement background layer. You would then add the layer mask containing the silhouette of the lower layer object and unlink the mask. Your inverted selection. The mask does not need to be very good for any fringe areas cut off by the mask would still show because of the multiply blending. Unlinking the mask let to move the replacement around.
original image
Replacement background on top set to multiply
Add layer mask and unlink it
unlinking the mask gives you the ability to move and position the replacement background

I used the quick selection tool to outline, then refine edge....
my image does not shoe up in the refine edge window....it is a "mask"..
then when I output to "new layer with layer mask"....my "subject" t is gone...back ground remains...Thanks for your prompt reply!
this is how the "finished" product looks...this is the image after I select "output to mask"..
It seems "reversed"? -
I'm having a small but annoying issue with FF10. In the past, I have watched a video on a website that I visited to get information on a diet for a family member. I have not visited that site since obtaining the information on the diet, but now, sometimes the audio from that video will play in the background when I am browsing with FF10. This issue has not occurred with any other browser, so far as I am aware. My first thought was that I may have a virus, but I run virus scans every day, and all of them have come back showing no viruses. I have run Norton Internet Security scan in both Safe Mode and Normal mode, all with the same result. My PC is less than a year old, and everything seems to be running smoothly, apart from this problem. It does not happen every time I open Firefox, but sometimes happens at start-up, or more rarely, after I've been browsing for a while. Apart from the repeated virus scans, I have also attempted to clear any cookies related to the site I visited. I am waiting to see if this solves the issue, but I'm wondering if anyone else is having or has had a similar issue. If you have, any help would be much appreciated.The audio of the video was annoying to listen to once, and I'm hoping I do not have to keep hearing it so often, so if you have any suggestions beyond what I have tried, I'd be extremely grateful. Thank you.

Selecting contacts by group when syncing with Google contacts
I sync my iPhone with Google contacts, however, ALL contacts are sync'd. I have many groups that I don't want sync'd, such as "people who appear in my Picasa photos that I don't have/want contact information, like Bob's friend Pete". I have to suffer with these insane entries in Google contacts, but I would like to exclude them when syncing with my iPhone.
Is there any way to do that?
Is there any way to make such a request to Apple?
ThanksI can't help but feel this should probably be on an iphone forum, not itunes.
If you want to address people who work for Apple you should provide feedback through their feedback sites which you can find under "contact" at the bottom of the page. Pretty much the only people who respond these forums are other Apple product users like yourself, sharing their experience. -
I'm trying to use the Refine Edge tool to remove the person in the attached image from the background. I've read some tutorials and watched the Russel Brown Adobe tutorial, though I'm still confused.
I did the following steps:
- I made a loose selection around him
- turned off smart radius
- draged the radius slider all the way to the left
- clicked on the refine radius tool
- drew around the edges of the hair
- refine the edge by dragging shift edge to right
The results do not look good. What am I missing? I'm confused by the refine radius tool? What should I be doing with the refine radius tool? How should I be drawing over the person?
Thanks.Probably the best advise you can ever get is that from Russell Brown - sorry, Docter Russell Brown that is.
Go to http://www.russellbrown.com/tips_tech.html and pay special attention to the Masking techniques. You could for instance start with CS5: New Masking Basics / Episode # CS5_008 (scroll down a bit). If you go on and watch his other tutorials on this subject, don't be confused by the phrase Refine Mask, it's the same as Refine Selection.
May you have other questions about PS techniques then you'd better first see the Docter! -
Problems with refine edge in CS5-no longer working properly?!
Hi all, just wondered if anyone has experienced this bizarre problem and if so how they went about fixing it or changin the settings! (i may have done something to photoshop for it not to work properly!!!)
Basically, i have got CS5 and was very excited to find the refine edge tool.... made cutting out people real easy and loved it.... however, for some reason the refine edge is not working anymore. Everytime i try to refine the edge using the refine edge tool it isnt selecting any fine details of the cut. It seems to be erasing the image with a low opacity making the selection very blurred?!
Hopefully you can see from the very quickly put together example that the refine edge tool is taking pixels out if her nose, chin, jumper neck and jumper! Any one know how to prevent this from happening?
Thanks! MattI am having the same problem with the refine edge tool. It seems to work the exact opposite of what I was expecting.
The above two images are before and after using the tool to refine the edge. As you can see from the picture without the mask view, the selection actually got smaller after I tried to add to it. When I use the other tool to erase an edge, as soon as I release the mouse button, the portion I tried to remove reappears as it was before. This has never worked properly for me. Also, I have tried outputting in several different ways.
As for the questions posed: The app and OS are up to date. I am the only user on my computer, so I'm not sure what using another user would accomplish. I will mention that I'm using Windows 7, not Mac. I'm really hoping there is a setting I have wrong somewhere. -
Getting poor results with Refine Edge tool
Not sure if anyone else has run into this issue. But after following numerous tutorials on lynda.com as well as tv.adobe.com and youtube, I just can't get good selection results using the Refine Edge tool in Photoshop CC and I'm convinced it's something I'm doing wrong, but I have no idea what.
After downloading this Wikipedia image of Bismarck for a history documentary, I tried isolating the figure from the background using Refine Edge and keep getting poor results. Maybe it's my settings, I'm just not sure. But after painting over my edges, I end up with terrible results. Unfortunately, I'm getting poor results with other images as well. Can anyone venture to guess what I might be doing wrong? Thanks very much in advance.Hi ninose11,
For this type of project and idea, I would recommend trying some of the magnetic lasso tool. The tool is located as the third tool in the toolbar (you should see a lasso or rope looking icon), hold down the icon and it should expand - then select the magnetic lasso tool. The magnetic lasso tool will allow you to scroll over the edge of his profile and it will automatically detect the outline edges. The slower you roll-over the shape the higher the accuracy will be. If the magnet is not detecting a particular edge or sharp corner (for example, the ear) you can manually drop points by simply right-clicking at any point during the selection. If the edge is too sharp, you can also create a light feather which will blend the edge softly (this should be located at the top).
If this is unsuccessful still, you can try selecting by color, using the Magnetic Wand Tool (forth icon in the toolbar, again hold down for all options). Once you are using the magnetic wand tool, you should be able to select all the black areas of the background to delete. You can increase or decrease the tolerance to change the sensitivity of the selection.
Hope this helps! -
Hi,
I have tried it all and cannot say that I can use Refine Edge/Mask successfully. I have seen tutorials in youtube, in lynda.com, etc and they make it look so simple! I keep getting horrible grayish tones in the edge of hair. Please I am desperate. I am attaching a the mask used, the base image and the resulting image and the settings I used in the Refine Edge dialog box. Tell me what I am doing wrong!!
Thanks
Juan DentThat should be a reasonably easy selection, but I absolutely agree that Refine Edge is not half as intuitive as the tutorials make out. I'll try and give a few hints that will hopefully put you on the right track.
With an image like the above, think in terms of only using the Refine radius brush on the whispy hair, or little items that protrude from the bulk of the selection. Try to get the rest by using just the sliders and Smart Radius.
When using Quick Select, toggle on and off Quick mask to see if you are missing anything. I much prefer to have Quick mask set up with 'Color indicates selected ares' (double click the quick mask icon at the bottom of the tool bar to change this).
If you suspect you will need to fix the result of Refine Edge, chose to output to 'New layer with layer mask'. Add a new layer below that layer, and fill with a bright colour to increas contrast and help with touching up the Layer mask. You can Shift click the layer mask to temporailly turn it off to reveal anomallies.
If you are going to use the selection in another image, then duplicate the new layer with layer mask to that image. That way you can use the Mask Properties panel to refine the mask and fine tune to the new location.
Good luck. -
Issues with Refine Edge adjustments
Using CS5, WIN, 64bit, bamboo tablet.
I'm working on hair & after making a selection, I open the refine edge tool & selected brush to tweak the selection. However when I attempt to paint in an area or paint out an area my selection disappears right after I make it. I am including 2 photos in an attempt to demonstrate what's going on. The 1st screen shot may not show it but the settings in place are listed below. The 2nd image shows an area that was selected for additional refinment. What cannot be shown is what took place after the selection was made but, he selection disappears! the 3rd image shows the results. clearly I am NOT doing something right, any advise/recommendations?
VIEW MODE - overlay
EDGE DETECTION - none (no smart radius)
ADJUST EDGE - setting vary
OUT PUT - none selectedhttp://www.youtube.com/watch?v=jI-9Mr7cLBY

Error occuring in SELECT statement FOR UPDATE when using WITH cluase
Hi,
Iam using oracle 11g version
Iam having a query with fetch records for update insid with cluase as
cursor c1 is
With abc as (
SELECT col1,col2 from table1, table2 where < condition>
for update of <col1> skip locked
select * from abc,table3 where <condition>
union all
select * from table4 where id not in (select * from abc)
if i add "for update of <col1> skip locked" this cluase
iam getting error ORA-00907: missing right parenthesis
when i remove "for update of <col1> skip locked" the block is working fine..
can i know why error is occuring iHi, first of all, your placing of "for update" clause is wrong. It should be at the end like:
With abc as (
SELECT col1,col2 from table1, table2 where < condition>
select * from abc,table3 where <condition>
union all
select * from table4 where id not in (select * from abc)
for update of <col1> skip locked;Second, if you try to compile it with this syntax then you will get a new error.
ORA-01786: FOR UPDATE of this query expression is not allowed
Cause: An attempt was made to use a FOR UPDATE clause on the result of a set expression involving GROUP BY, DISTINCT, UNION, INTERSECT, or MINUS.
Action: Check the syntax, remove the FOR UPDATE clause, and retry the statement.So, you will not be successful with the union clause in your query. -
Error when extraction with generic datasource using function model
Hi,experts,When i check the error log in bw side for one egeneric datasource from R/3 side , it shows all the data from the datasource has been extracted ,and the error lies in the data selection .But when I use the Tcode RSA3 to check the datasource to check the functionality of selection ,its seems ok .
Could and I give me some clue ?Hi,
Seems function module checks the selection in the infopackage while loading the data. Could you check if there is any selection which is expected but not given in the infopackge or incorrectly given.
Hope this helps.

Refine Edge with complex background
I am working on an Easter poster for my family, and I found a photo of a bunny on wikimedia commons that I liked (shown below). When I first looked at it, I thought, "I've used the refine edge tool a few times before. I can isolate the bunny from the setting, no problem!" Well, two hours later I was nowhere near having the kind of results I expected. What I need to know is, is it my cursory experience with an advanced tool (by comparison) that hindered my efforts and I just need more practice with refine edge, or is the complexity of the grassy background just dooming any shortcut from the start and leaving me with no good alternative to pixel-level editing? If the former, I would be highly receptive to any suggestions to settings and/or methods using the tool.
And yeah, I know there are many, many more bunny images out there. But this is more about my judgment and skill level w/ Photoshop than it is about one small project. Striving to get where you folks are. Any input greatly appreciated.
Thanks,
- DKThat's not a great image. Like you say, Refine Edge is not going to give you a great result, and the rabbit is out of focus and the lighting flat. It's even particularly big, (unless you downsized it to upload to this forum) Seeing as you found it on the internet, I'd be strongly inclined to go find a better example.
There are several hits with rabbits on white backgrounds, which will make selection so much easier. GOOGLE
But if you really want to use Refine Edge on your example, have a look at this Martin Evening tutorial, which is the best of its kind I know of for that sort of subject matter. -
Using Refine edge with Quick Selection......
I think I'm doing something wrong, because I can do a quick selection, but when I hit the "Refine Edge" button and make a change to the selection, my change doesn't "take"...
I have an image, one layer (background), absolutely normal, boring image (for example, a white swan sitting in the blue water). I go in with Quick Select and select PART OF
the swan. I have areas that aren't selected, and areas that are selected and shouldn't be. So, I need to refine my selection. I subtract and add bits of selection with the
Quick Select tool, but leave a big piece of the swan's body NOT selected, and a bit of water SELECTED. So, I need to go in with a tool and refine the edge of my selection...
SO, I hit "Refine Edge" from the tool bar and select "Overlay" for my view mode. I can now see what's selected, and know what I'd like to change. And, I have a red overlay
so I have a visual guide to changing things....
Go to the "Refine Radius Tool" and paint over an area I want ADDED to my selection (a piece of swan immediately adjacent to my original selection)... It runs red, like I'd expect.
I release the mouse and a second later, the red goes away, but the selection has NOT been changed. I've tried this directly from the Quick Select tool. I've double-clicked the
background layer and changed it so it's not background any more - made no difference. I've created a layer mask on the no-longer background layer (the mask contains my
Quick Selection just fine). I've then used the Mask panel to specify "Mask Edge" and again tried the "Refine Radius Tool" to add an area to my selection. Again, it turns red
while selecting, then stops being red when I let go, and the area I selected is NOT added to the selection...
I watched a presentation by a Photoshop person who DEMONSTRATED exactly what I'm doing, and it worked. I looked at Martin Evening's CS5 book, and as near as I can tell,
I did exactly what he described... He got a selection, added to the selection, and it worked fine...
I figure I've got something configured wrong, or something else goofed up. What am I missing here?It's not my intention (intent?) to beat up on the "Refine Edge". I figured when I couldn't get the same pristine results as all the demos that I was doing something wrong, and kept watching more people doing this 'cause I figured I was doing something dumb...
Mostly, I've been trying this on different images over the last couple weeks just to see if I could figure out how to get it to work.
From the responses in here I suspect I'm doing it correctly, but the images I'm trying it on just don't lend themselves to perfect edges without some additional work..... The Quick Select and a bit of edge cleanup is still faster than the "good old days", so its definitely a step forward.
As far as the swans, yes, no matter what I did, I was getting a lot of extraneous selections and wonky edges and stuff. One of these days I'll try pulling an eagle or a great egret out of a clear sky and see how that goes. I suspect it'll work a lot better...
I only fiddled with the rodeo image 'cause I figured it was "like" hair. But my background is pretty busy. With a little additional work I DID get a very, very good selection, and was able to soften the background, and do a gradient so the ground under the horse is sharp, gradually blurring as it moves to the grandstands...
Thanks for all the replies... -
Pragma error when compiling with SDK X
Hi,
I am trying to compile my plugin application (which compiled fine with the previous sdk) using the SDK X, but receive errors in CAVAlert.h on the exception handler construct DURING, HANDLER, END_HANDLER.
The errors are listed here:
Headers/API/CAVAlert.h:156:3: error: 'suppress' was not declared in this scope
Headers/API/CAVAlert.h:156:3: error: 'warning' was not declared in this scope
Headers/API/CAVAlert.h:156:3: error: '__pragma' was not declared in this scope

Headers/API/CAVAlert.h:162:3: error: expected ';' before 'int'
Headers/API/CAVAlert.h:165:3: error: 'ENDHANDLEROutsideHANDLER' was not declared in this scope
To compile against to SDK X all I did was:
1) Used PIMain.c from the SDK X API directory.
2) Changed ACRO_SDK_LEVEL=0x00090000 => ACRO_SDK_LEVEL=0x000A0000
3) Changed the include directories to point to the new SDK X directories
Is there another directive I must add to get the plugin to compile with SDK X?
My preprocessor list is as follows:
ACRO_SDK_LEVEL=0x000A0000
HAVE_W32API_H
PDMETADATA_HFT=1
PLUGIN=1
WIN32
WIN_ENV
WIN_PLATFORM
WXUSINGDLL
_CRT_SECURE_NO_DEPRECATE
_DEBUG
_WINDOWS
__GNUWIN32__
