Poor panorama blends (straight edges) in CC2014.1

I have Photoshop CC and CC2014 installed on same Win 8.1 machine. CC produces good panoramas with the expected "jagged" masks between images but, for exactly the same images and panorama options, CC2014.1 produces straight line masks between images and poor blends. I don't have the original CC2014 available to try that so not sure which version first showed a problem. My versions are both "up to date" in Creative Cloud (as of 10 Aug 2014):
CC: 14.2.1 x64
CC2014: 2014.1.0 (20140730.r.148 x64)
Although I can run the older Photoshop CC manually to create a panorama, the Lightroom "Edit in/Merge to panorama" option will open CC2014.1 and produces the poor blends. Can anyone shed any light? Thanks.

I can confirm that there is a difference in the frame masking with Photoshop CC 2014.1. Note the edges of this particular frame in one of my panos as stitched in Photoshop CC 2014.1 vs. 14.2.1:
However, is it worse? I noticed that Photoshop CC 2014 has seemed to improve the "big picture" blending between adjacent frames in Photomerge, Perhaps it's just because of the change in the mask positions, but to me the overall exposure differences between adjacent frames seem less visible when looking at the pano in overview...
Are you seeing that some panos appear more poorly stitched with the simpler masking?

With the new update has gone the option to blend the edges of the images. An indispensable tool

Ibán,
Apply the Picture Frame effect in Pages V4, then paste into Pages V5.
It's inconvenient, but then many things are in Pages V5.

How to Blend Image Edges with a Gradient

Hi All
I've created a transparent gradient over an image. The problem I am having is that the edges of the image are visible beneath the gradient. I know how to correct this in Photoshop but I am having difficulty in Illustrator.
How can I create a smooth blend of the gradient over the image without seeing the edges of the image?
Thanks
George

If the background of image that you have underneath the gradient is a uniform color (it appears to be a uniformly white background, as best I can tell), you might also try adding a rectangle the same size as your gradient below both the image and the gradient, and fill it with white (or whatever the specific background color of your image is). This will only work if you have a uniform background color around the edges of your image, but it looks like in your example that it might work. (see attached)

Blending in Edges

HI,
I'm new to Photoshop and am trying the following. I have Adobe CS3 and created the following in Photoshop.
I created 3 layers. text, Image and white, but originally I opened an image with Photoshop and renamed the background layer to image
On the text layer I created a title of some place
On the Image layer I created a mask and then ran a gradient horizontal (from left to right) for about 3/4 of the canvas.
Now what I want to do is blend in the right side of the edge so that the white layer will show through as it is on the left side due to the gradient.
I'm not sure how to so this. Any help will be appreaciated.
Thanks
Steve

Hi Noel,
That worked for me, it was exactly what I wnated to do.
Thank You

Using IMAQ Find Edge and/or IMAQ Find Straight Edges 3 In order to return tip coordinates of a needle

I know that there are functionalities in the two aforementioned functions that allow for start and end points to be found and output after a straight line is found in an ROI. My problem is that these start and end points are with respect to the ROI, and not the the actual object. What I mean by this is that if I have a needle (whose tip is in the ROI) and try to find the corresponding edge, the edge is easy enough to find. However, the red line that is superimposed on the image, representing the found edge is extended past the tip of the needle, and carried until the boundary of the rectangular ROI I am using. Thus when I return the end point, it gives me the end point along the ROI boundary, not the tip of the needle.
If anyone knows how to obtain the coordinates of the actual needle tip using the edge funtions in the post subject line, that would be very helpful and much appreciated!

If the needle is of the same height you can adjust the ROI accordingly. Also by tip do you mean the tip point?

Stroke won't curve and has straight edges

Any idea why this happens? I applied a 1pt stroke as you see in the screenshot and I gave it a default width profile. For some odd reason no matter what I do that stroke has sharp edges and isn't curved smoothly.

So when will they have a fix for this?
send a bug report, but nobody in this forum can tell you when it will be fixed.

Why is elements better at photomerge than CC- CC does not appear to automatically fill image based on content but elements does when merging a panorama. Also the stitching is visable in CC but almost perfect in elements- why?

I took 6 panorama shots of a scene and used CC to Photomerge them as one. Couldn't see where to automatic blend the edges and there was 'stitch' lines when the images were merged. So i did the same in Elements 11 and it was perfect. Am i doing something wrong in CC or perhaps not doing something at all?
Any help, please?
Dave

Hi - Thanks for taking the time to reply and i appreciate the remarks- if a little harsh- we all have to start somewhere and i am fully aware of the limitations of Elements which is why i decided to add CC to my software. I can only say that if an inferior quality software from Adobe does the job well then CC must also be suited to doing the same which is why i can only think, from your comments, that i have not done something simple- however- following tutorials to get to the end result should have sufficed- it didn't so perhaps i will consider posting the difference between the two applications- and, perhaps suffer a few more 'harsh' comments. The learning curve is quite steep and i am a visual learner, but i'm also not totally incompetent:)
Kind Regards
Dave Munn

First a clarification: you are not addressing Adobe here in these user forums. You are requesting help from volunteers users just like you who give their time free of charge. No one has any obligation to answer your questions.
I'll give it my best shot anyway.
Few folks in this forum are really familiar with Elements, for which there's a dedicated, totally separate forum.
Different engineering teams, also.
From this perspective, it will be difficult to give you a direct answer to your "why?" question.
Personally, I blend very large panorama shots in Photoshop proper since I can't even remember when without any issues whatsoever, up to and including in Photoshop CS6 13.0.6.
Without being at your computer and without looking at your images, I couldn't even begin to speculate what you are doing wrong in Photoshop, which I suspect you are. The least you could show is post examples from your panoramas that have gone wrong.
I can tell you that panorama stitching requires significant overlap between the individual shots, besides common-sdense techniques like a very solid tripod and precision heads.
The only version of Elements I have ever used for any significant time was Elements 6 for Windows, which I bought in 2008 to use on a PC (I've been an avid Mac user for 30 years). I found Elements so limited and so bad that I successfully demanded a refund from Adobe. IU mention this only to emphasize that I can truly only address your question from a Photoshop (proper) and Mac user point of view. I couldn't care less about Elements, but if you have comparison examples of panoramas processed in both applications, by all means post those two.
Generally speaking Photoshop is a professional level application that makes no apologies for its very long and steep learning curve, while Photoshop has many hand-holding features for amateurs and beginners.
Perhaps the bottom line is that you should stick with Elements if you personally manage to get better results there.

Photo Merge now creates straight line merges...

In the old days when I did a Photo Merge from Bridge I would find that the merged document would have multiple layers with masks that had quite irregular edges (as expected) and therefore smooth fills. Ultimately PS produced really good panoramas with VERY LITTLE EFFORT required.
Sometime recently, and I'm not sure which CC update it was, this all stopped working and now my merges have straight line edges and sharp non-graduated fills. Where the panoramas have straight lines in the shots or clear changes (like skylines) they jump at the merged edges and are not smooth.
What has happened? What am I missing? What new settings are required to use Photo Merge? I have checked all the obvious places in both BridgeCC and PhotoshopCC 2014 and nowhere does it mention any new controls. I have checked the various help videos and nowhere do they use any methods that I do not use. Why do they get smooth transitions when I am not?
Now I am using PSCC 2014 on a Windows 7 laptop with a smallish hard drive (SSD) and not a huge amount of room (20-30Gb drive available at most) but this wasn't a problem previously and even when I make more space available the problem persists. Am I going to have to wait until I am home and have access to my desktop with 32Gb RAM and TB of available drive? Hope that isn't the case as it will be 3 months away.
Now if this website would allow me I would add a JPG of the PS window to show the problem but it won't let me upload the file even though it is less than the 4Mb limit in size. Then we get back to entering this forum which required me to log-in to my Adobe ID 15 times before it let me start a discussion...

I've finally managed to get a screen shot into this forum.
I have deselected 2 of the frames to show the straight edges of the masks.
Now zooming in to the right hand join we see the skyline has an abrupt join...

Photomerge blend image no longer uses a "ragged" mask - blend boundaries are now obvious

Not sure if this is just me ... but I think the behaviour of the blend image process has changed since the latest update to Photoshop CC.
Previously, when images were blended together it would generate a mask with "ragged" edges. This was brilliant (almost better than Autopano Pro), since it made any blending artefacts almost impossible to discern, particularly when there were slight changes in the light between images. Now, the blending masks generated have straight edges between masked and visible areas - the blend sticks out like the proverbials. So far as I'm aware I'm using the identical workflow, and I've searched to no avail for an option setting somewhere that controls this behaviour. Can anyone help, please?

Hello!
I hope that I understand what you need.
(One could just put the image on a layer, and lower its opacity, but you seem to be looking for an effect in wich the tranparency is not the same for all pixels.)
Try this:
1) Turn your image image as a layer (double-click it if it is a background layer) [In order to add a mask]
2) Select all, Copy (CTRL+a, CTRL+C)
3) add a layer mask (click the rectangle with a circle in the bottom of the layers panel) [to be able to change transparency]
4) target the mask [so that you can past an image in it] ALT+click the mask, paste the image.
5) Invert the colors of the mask (CTRL+I) [in order for the white to be transparent and the black opaque].
You now have a layer whose transparency is based on the lightness of the pixels.
Hope that's what you are after!

Straighten horizon in panoramas? Lightroom to Photoshop CC

I am using photoshop to stitch together 40 photos of the grand canyon I'd like to combine into a larger panorama.
The photos are in Lightroom (Canon Raw files from a 5D mk ii). I highlight them and select the merge as panorama in photoshop option.
I choose perspective combine (the first option).
Once the photos are combined (a process that takes about 15 minutes), the horizon is very, very curved, and heavily distorted, as if the photo was taken with a fish eye lens (each individual frame is shot at 70mm).
What is the best way to straighten the horizon and remove the distortion to make the photo appear natural?
Lastly, I want to maintain the RAW info so that I can edit the photo to it's full potential in lightroom, however photoshop only lets me export hte panorama as a tiff or jpeg. What's the best way to retain as much information as possible in this scenario?
Thank you all for your help.

The result looking like a fisheye is probably normal because your combined angular field of view was very wide, right?
The horizon being bowed is because you didn’t shoot your images equally distributed above and below the actual horizon since the Grand Canyon is all below the horizon if you were shooting from the rim, or mostly above horizontal if shooting from the canyon floor. The panorama creation algorithms don’t know and just guess that the horizon is halfway from the top and bottom of the images, at least if there are no clues from vertical poles or straight edges in the image.
Anyway, what you need is different software that allows adjusting the horizon point up and down, as well as changing the projection after the stitching has occurred.   There may be some way to use mapping of your panorama onto a sphere and then use 3D manipulation in PS but I am not sure how to do this so cannot really advice if and how it might work.
What I would recommend is getting dedicated panorama software that allows extensive tweaking of many things including the horizon and projection.
One possibility is HugIn, an open source project that is both free and complicated to understand although very powerful once you do. I’ll let you Google for it, as I remember it wasn’t too hard to find.
The product I use which is also reasonably powerful and a lot easier to understand but also not free is AutoPanoGiga from http://www.kolor.com/   I think it has a trial option so you can get the feel of how it works before deciding if you want to pay for it.

Panoramic Pictures

How can I make panoramic pictures using Aperture? (Combine 3 to 8 pictures of one object, then stich them together for on one long picture.)
How can I blend two or three photos together to have total focus range in a final photo? (Not HDR) (Example: I take one shot at far focus, one shot mid focus and one shot near focus. Then blend them in to one picture all in focus using Aperture.)
If Aperture cannot do it is there a plug-in for Aperture that will build a panoramic picture or allow me to blend photos together?

Welcome to the forums.
Not too sure about the panorama plugin, I know that Pshop does a great job of this.
As for the blending of pics for infinite focus, totally different kettle of fish. Panoramas you are essentially blending the edges of pics together. Focus is a subjective and variable quantity, each lens camera combination giving differing results, each scene with varying contrast and subject matter, a very big ask for a one click plugin. As you move the focus point the image changes, think of being focus on a face with the background blurred, now change to the background in focus the face blurred, that line where the two meet, how do you define it? Suggest some in depth reading of how images are projected on to the focal point and the circle of confusion resulting.
An example, using the HDR technique ideally you should either introduce a neutral density filter or adjust the ISO, as changing the aperture changes the image enough for it to no longer overlay perfectly.
OK they are the reasons why not... how to do it?
1. Get your self a tilt lens and learn how to use it for the Scheimpflug principle.
http://en.wikipedia.org/wiki/Scheimpflug_principle
2. Get a wide angle lens, use a small aperture and get a large depth of field.
3. Use photoshop, place each image on a layer, give each a layer mask, using your discretion brush away the areas of each image you do not want.
Love to hear of a plugin!

Blend tool doesn't create smooth blends - how do I fix this?

Hey guys and gals,
I can't seem to figure this one out. When I use the blend tool for a smooth blend, the blends comes out jagged and horrible, as if it is doing a step blend rather than a smooth blend. I have used the tool before by either using the shortcut (Alt+Ctrl+B) or using it via the Object>Blend pathway and it worked out fine, but now Illustrator doesn't want to create a smooth blend.
What I'm trying to say is; is there an option that is causing this to happen that I may have accidently turned on, or has my copy of Illustrator gone into stupidity mode and I need to reinstall it?
I've attached pictures of what I mean with the settings I'm using and outputs. I hope your collective minds can smack this one in the face. I'm sure I'm doing something ridiculously simple to cause this.
I'm using CS5 Illustrator and my relevant PC hardware is listed below.
- Intel i5-2500 3.30Ghz
- nVidia GeForce GTX 560
Thanks in advance.

In this case, the sawtooth patterns corrspond to the corners of the large number of different intermediate shapes sticking out.
So basically the shapes straight edges and corners are the cause of my problem, the smooth blending I was experiencing earlier which appeared smoother was actually because I was using a more rounded shape?

IMAQ Find Edge shows straight edge beyond part

Hello
I am working on finding the sides of my simple part with the IMAQ Find Edge tool. To make it simple, I gave my image an extreme threshold with IMAQ Threshold manually set 0 - 230 so My part basically shows up Black against a white background. I set the ROI of the Part from IMAQ Count Objects 2, expanded that ROI by a couple pixels on each corner of the bounding box and input that into my IMAQ Find Edge tool. I have two IMAQ Find Edges, one looking left to right finding all edges and the other top to bottom finding all edges. It took a while, but I have all Straight edges appearing using the results from Find Edge.
What I don't understand is why these lines are longer than the edges of the part sides? I have attached the image to show what I mean. The edges (yellow) are clearly found on the part, but the resulting lines (red) are beyond these points.

Also am I setting up my edge detect functions wrong? I am filtering my image so I only see the object, no shadows. I am thresholding the image to basically outline it. Now I am using the edge detect function to find the edges and it can't seem to find them all. I have an object that I set my ROI about it, and I have the settings for the edge detect on very low to detect basically any edges possible. It still does not consistently see the edges of my object.
Is there a more reliable way to consistently see these edges?

How do I remove halftones at shape edges?

I am new to Ae. When I make shapes there are these annoying 1 pixel half tones at the edges and they are really visable in this blue colour, if I turn off anti alias (can you even do that in Ae?) the curves will look bad. So can I just snap the straight edges to the pixels or something?

Those are caused by subpixel interpolation. Select your shape layer and press the u key twice to reveal all of the modified properties of your shape then fix the size and position of your shape so that everything is a whole number. If your rectangle is an odd number of pixels high or wide then the anchor point value must.be at a half pixel. IOW if the rectangle is 51 x 100 the anchor point must be sent to 25.5, 50.
Once you start animating position the anti-aliasing will take over again but this usually causes no problems because you cannot judge the quality of your video from a single frame, you have to make your judgment call when the video is playing at speed and full-size on the device you intend to use to present your video. And other words you can't tell if your project is perfect unless you watch it on television if it is intended for television or on a computer monitor if it is intended for YouTube.

Straight line tool?

I recently used the clone tool to edit out the background of an image and leave the stone cross highlighted against the sky. The cross has very straight edges and even with a steady hand and lots of zoom, I couldn't get the edge of the cross really straight. I bought a Bamboo Pen & Touch but that didn't really help. Either I need a straight line tool or perhaps 'detect edges' but I can't find a line tool and detect edges doesn't seem to apply to the clone tool.
Any ideas anyone?

No straight line tool in Aperture. You'll need a photo editor for that like GIMP or PS. And as you've seen the clone tool doesn't have a 'detect edges' checkbox.
Aperture isn't really meant for the type of photo editing work you seem to be doing. You can make do but again a photo editor would really be the way to go.
