Camera: Touch Focus for Defy

I learned how to use Touch Focus using the ROM MS2Ginger 1.0:
open the camera app,
press and hold the white square in the middle, drag it to wherever you want and drop.
Press and hold the capture icon, the square becomes green in the place you dropped it.
When you release the capture icon the picture is taken.
Remember to clean possible dirtiness or fingerprints from the lens.
I would like to know if there is a way to use this feature (or bring it) in other ROMs, and if it works in both red/green lens.
If you try please share your result.

IMO, the best & simple way for using touch to focus is Camera360.. This is the best camera application. Offers various cool effects & also touch to focus option.
Its pretty cool..

It works, and has many configurations, thanks.
Does touch to focus works in your stock blurcamera as I described?

Many camera apps support touch to focus, like LGcamera and Camera360.
But I hope you know that the defy itself doesn't support touch to focus, so when using the app it may appear that it is working but it is still focussing on on the center:

The next page the dev says that moto's driver doesn't support it and that there is nothing that can be done about that.

Only now I found the setting that I had to change in lgCamera, Touch Focus is working there too, thanks.
I've attached some pictures made with my Defy using focus in different objects, can you confirm if you can do the same?
Maybe it's ROM/lens dependent.
EDIT:
I've attached both reduced size and full size.

This manual touch focus is working for Defy. I'd tested it many times with difference objects far and near and they seemed to work very nice. I use the stock camera as it integrated with my blur galery very good and easily share or upload it to my social network apps.. This Defy even worked with the face detection and sometimes I even use it to take group of peoples without any issues.

can any of you actually tell me how to get touch focus working on any of the camera apps?stock,lg or 360 i can't seem to find the settings to change it to touch focus..

Try taking a photo like the one attached, with your fingers kept at the center and very close to the camera, while clicking on the farther object to the side (here my laptop). The camera will still focus on the nearer object, the fingers, at the center of the screen rather than at the object you clicked on . So touch to focus isn't working the way it is supposed to, it only just focusses at the object at the center of the screen whenever you touch anywhere on the screen.
I am on CM7 RC1.5, SOC Module. Touch to Focus probably won't work the way it is supposed to unless someone can fix the drivers moto has supplied for the phone. If it is working properly on your ROM maybe it can be ported

I don't remember if Eclair or Froyo has this touch focus function under stock rom. But I'm positively sure all gingerbread stock rom has it, however, it still dependance on Red lenses and Green lenses capability I supposed. Custom rom like CM7 or Miui may have altered alot which makes this function disappeared only the rom developer knows.

@scottie1973
for camera360:
go to definitions (wheel in top right), "Common Set",
make sure "Shoot by screen touch" is checked,
and that the "Shoot Mode" is defined as "Auto Focus".
for lgcamera:
you need to open definitions, and in the end of the list are a lot of checkbox to be selected.
In mine the words are not in english, but it's related to long click to Autofocus and capture.
For the stock is as described in the first post.
If after autofocus, the square is turning blue instead of green, means that the camera was not able to focus correctly.
@tejus.k.v
It works that way, even though I notice that there is a minimal area of a object for you to be able to focus at it. I don't know if this thing is perfect or not, but it works in the ROM I'm using (developed by walter79).

Camera preview is cropped

For quite a while, I have noticed that the preview in stock camera app which comes with several ROMs is simply not full screen, but rather cropped. Final images looks fine though.
I'm currently on latest nightly Rootbox and problem still persists. Is that normal behaviour?

Well if you refer to the fact, that the final images include a wider/higher(depending on orientation) image than the previewed, it's because the camera sensor has a different aspect ratio than your screen. This means that either google had to put 1cm black bares on the top and bottom of the screen in preview mode or they could use the entire screen to show a cropped preview. They chose the latter, and in that case they could either crop the final image as well or include the full photo. Again they chose the latter option.

That was a foolish choice then. The point of a preview is to show what your photo will look like. The gallery displays photos properly and so should the camera. I don't need a full screen camera display, but I do need to see what my picture will look like before I take it.

Well I'll have to disagree with you on that one, we are talking about a mobile camera, and a bad one at that. This is no expensive high end dslr. Your image includes everything shown in the preview and more, allowing you to crop the image if you coincidently included something not meant for the picture.(the phone even includes an easy tool allowing you to do this) This fits the usecase in which a smartphone camera will actually be used, e.g. point and shoot to save the moment, perfectly.
Had they thrown in huge black bars everybody would hate the camera app, and to me a cropped 16:9 image is horrible, leaving only one viable option. I get that you disagree, but that doesn't make it a stupid decision.
edit: Even apple was forced to make the same design choice on the iphone 5 because they switched to the 16:9 screen ratio:

I can't agree with that at all. The old camera was not full screen and I liked it much better because it was easier to use. The current one it seems to be all form before function, this full screen preview being just one example.

Correct but that wasn't at all the point i made, which you would have known, had you read more than the first sentence in that paragraph. The point is that this is not a camera used to take high quality precision photos. This is a point and shoot camera, and for that purpose you don't lose any function, making it perfectly justifiable to prioritize the ui.(hence that is what the average user would prefer, since they would never notice the preview being cropped)

Auto Focus before snapping picture?

Just got this Galaxy, amazing phone and whatnot, and installed wicked rom.
Tried all three camera's (GE, stock, moto) and none seem to auto focus right before a snapshot. It only auto focuses while the camera is active not right before taking it its own and this causes me to take blurry pictures (I have horrible steady hands). Basically it focuses only before I click the snap button I want it to do it automatically after I click it.
My old E4GT however does it and it is one thing I loved about it. It would take a second to capture the picture but it would take it in perfect focus because it would automatically detect it right before the shot after I click the snap button.
Any ideas on how I can add that feature to this phone?

Mine auto focus after I hit the "snap" button. I'm on Infamous S4 V4 ROM so I can't speak for Wicked. It shouldn't be any different IMO. Maybe play around with the settings.

I just hold on to the snap button for about a second and that focuses it really good, and that takes really good quality picture.

The camera on the s4 is not as quick to take sharp pictures as my note 2 other s3. I've just learned to tap the screen to focus first before taking a pic. Or I just tap n hold on the screen for a few seconds and once I let go it takes a pic automatically

I'll try that ROM because this is really irritating how my S2 takes better pictures than my S4.
And even stock rom auto focus before you hit the snap not after which is really weird.

I believe I've noticed that if you hold the camera directed towards the focus of your shot for say, 5 to 7 seconds, although delayed, it will adjust by auto-focusing SLIGHTLY. Not as good as just tap on the area of the screen that you want focused.

He is saying he wants it to re-focus AFTER the shutter button is pressed before it actually captures the photo. So the process would go like this:
1. Camera opens
2. Point at subject
3. Auto focus on subject to frame the shot
4. Press shutter button
5. Re-focus
6. Capture image
Plenty of cameras out there do this, and as pointed out, ours do it when the flash is on. They will vary the amount of light from the flash and lens focus simultaneously to capture the best picture quality.
I don't see why it doesn't do this either, my old HTC did the re-focus after the shutter button thing and you get much more clear photos. I sometimes have to try a couple times doing close up shots of things like text on identification tags (so I don't have to write numbers down) with my phone myself, and I have "normal" steadiness hands.

Okay, you want it to focus once, then after its already focused, focus again? Really? Thats kind of defeating the point. You already have focus on the subject why would you need focus on it again? That makes taking pictures much longer a process. However, if it doesn't have focus already, and you press the shutter button, then it takes focus again. But i have no issues taking crystal clear pics unless i accidentally move while its snapping the pic. But the way it focuses now is normal and how it should be. Focusing twice is really pointless..

The OP was asking, not me, and he said he has shaky hands which is why he misses this feature. It only takes a fraction of a second for the camera to do anyway. A lot of phone cameras do this already and you don't notice it. Heck, most hand held digital cameras focus before capturing the image AFTER you press the shutter button.

Lol i wasn't trying to point fingers or anything lol. I am just extremely confused, if my phone doesn't have focus and i press the shutter button, it focuses then takes the pic. but if it does auto focus before i press the shutter button, and i move then immediately press the shutter button, it will refocus.. so i am extremely confused as to what the OP wants..

isn't this marketed as a "feature" called zero shutter lag? I use procapture the majority of the time and it focuses after clicking the shutter.

LG Camera takes ages to save the photo and sometimes losses it

I've noticed if you snap a photo with LG Camera app and immediately press the back button or switch off the screen, the photograph is not going to be saved and you will loose it. You really need to wait until you see a preview of it in a circle on the right side.
And that time can be up to 2-3 seconds, which is really annoying.
Native google camera doesn't have this bug.
Has anyone else experienced such behavior?

No problem here...... Just tried it.
If I snap and immediately press the back button it quits the camera app but if I go back into the app the thumbnail of the shot is there.
So no, my G3 takes the shot and saves immediately.

That's why it takes a while.. HDRs don't render instantly and need some time to process. The reason it doesn't save when you back out is because it's still taking pictures.

So, I understand that, but why does it need to discard the photo if I close it too fast ? Can't it just schedule the processing in the background like Google camera does ?
With Google camera if it is in HDR mode and I switch off the screen immediately after taking a picture, the photo will still be saved.

I believe it's because the way HDR works is it takes multiple pictures at different exposures and puts them together so maybe the lg camera takes the pictures more slowly and you're quitting it while the shutter is still open?

As I said before, a google camera app doesn't have this problem. It produces hdr fine, even if you close the app immediately.
Obviously you gonna ask why am I not using it. I find that lg camera produces better results in HDR mode.

I usually don't reply to semi trolly post but I just took an HDR and instantly hit the back button and it doesn't save. (Of course) but I did the same thing and waited MAYBE a second maybe less and the photo finished processing and saved even though I backed out.
@op does the phone close when you take a picture or are you just intentionally hiring the back button that quickly on purpose? I literally had to try to NOT take a picture to keep it from processing. In just curious why someone would back out of taking a picture each time so fast. Well an HDR anyway

I presume that LG camera made that behaviour intended, programmers decided that if back or home buttons pressed immediately after pic is shot then use decided not to save picture so camera stops processing completely and doesn't save photo on memory. I think it is not problem it is a feature.

1. I do not talk nonsense especially when photography is the subject.
2. My previous phone was a Z2 which I would hardly call inferior.
3. If you wish to take a non standard photo then you also have to allow the processor time to complete it's action. As such 3 seconds (which by the way it is nothing like this on my G3) is adequate.
4. What gives you the right to insult any user. All that was given to you was an example of a waiting period prior to doing something else. In no way did that give you the right to be offensive.

delay in capturing a photo galaxy s20 ultra

Hi all,
S20 Ultra here, have taken plenty of great shots with my camera, the quick updates since launch have fixed most issues people had at launch with the cameras but something that occasionally bugs me is a delay in capturing a photo after pressing the button, resulting in missing the shot.
Typical scenario - taking a photo of my kids , they move a lot so you dont have long to get a shot, I pull the the phone out, line up the shot and press the button and nothing, 1 second, maybe 2 and it takes the shot and its not the shot you wanted.
It certainly isnt all the time, sometimes the shot is pretty much instant, I am beginning to suspect its related to the auto focus, the phone doesn't focus quick enough or maybe doesn't think its focused (often it looks fine on screen) so wont take the shot quickly when you need it to.
Any ideas?

Yea it is the autofocus, gonna need to wait it out for updates, you can speed it up by disabling the AI like scene optimiser, HDR, shot suggestions, and any filters you have enabled from the top right icon above the view finder, mostly the selfie cam is having the worst issues with around a 5 second delay if there is a face in view at arms length, especially with a bright light behind you like a window
