Forum: Q & A Thread: Photoshop layer...	Re: Photoshop layer... Posted: 20 Jul 2007 at 15:53 GMT updated: 20 Jul 2007 at 15:53 GMT go to thread brush is used for different tools, I assume that you pressed brush, nothing else, brush is used to color the layer (colors are the squars) or a mask (mask is usually black and white thumb on the right of the thumb of a layer) I use colors black to clear or white to show up the layer under the mask, if there is no mask you first need to create it, check the value of the brush and opacity of the brush, also another layer could be on the top of the one you edit this is very hard to say what is wrong, you gave little description, a screenshot could help alert moderator
Forum: Q & A Thread: PTGui and masking the tripod	Re: PTGui and masking the tripod Posted: 3 Jul 2007 at 11:00 GMT go to thread not sure if I doi the same what John does but our ways are probably quite similar first of all you need to know that full automatic is never perfect, it can be ok, but no perfect, if you are happy with ok, then no problem, but if not, you will need to learn much more first of all you should first learn adding manual control points and understand the optimizer - this will take you around 2 weeks - do all manually then you will need to learn a bit of photoshop - masking, layers, copying etc - simple things really to coret nadir or zenith properly automaric is never good enough, though could be ok, but never perfect what I do: 1. do the stitchies for panorama excluding nadr/zenith 2. when pano is fine I import nadir and zenith photos and using panorama editor manually place them where thay should be (don't forget to put the right crop for these images) 3. I am too lazy to add control points to nadir and zenith photos so I just generate a psd file with layers 4. open psd file then manually correct stitches 5. generate 2 panos - proper pano withouth zenith and nadir - pano1 - pano with only zenith and nadir - pano2 6. open pano2 with pano2qtvr and generate cubes 7. find nadir and zenith cubes and rename them, then I delete the rest of cubes, close pano2qtvr without saving 8. open pano1 with pano2qtvr and generate the cubes (then kep it open) 9. open nadir cube from pano1 and nadir from pano2 in photoshop 10. import nadir cube from pano2 into nadir cube from pano1 - a new layer is created 11. edit the nadir manually, flatten and save 12. do the same with zenith 13. convert cubes into panorama in pano2qtvr as you see this is not a very simple process and needs from you some additional skiils, without these skills you may find some additional problems stitching like half of a man on your pano or 5 cars - the same cars, or lots of flares - you panos will always be just ok, not perfect forget automatics - strat doing things manually - this will learn you something, really alert moderator
Forum: Q & A Thread: PTGui and masking the tripod	Re: PTGui and masking the tripod Posted: 2 Jul 2007 at 18:54 GMT go to thread as far as I know - yes... and no you should not crop anything in PTGui, if you crop the bottom part, the top part will be cropped too yes - because you can overcome this in a few ways - generate a psd file with layers, then correct the bottom part or just cut it, or cover it( I would recomend you to keep it as you need to have the horizont right in the middle, if you crop it, the horizont will go down) - then you can put there something like your logo or so - then you can adjust the settings with pano2qtvr so the bottom part will not display to be honist, now everyone can stitch panoramas as automatics work quite well, but this is an example when a photographer doesn't know what to do as he too much relies on automatic stitching to make a good pano you need a bit more than a camera, a lens and a pano head, if you do not learn how to correct things on masks you may always find some problems alert moderator

Forum: Q & A Thread: Workflow in PTGUI?	Re: Workflow in PTGUI? Posted: 30 Jun 2007 at 20:15 GMT go to thread Mark, I remember myself when I were starting , this was hard, I started with PTGui 3,6 I think, I needed some help, I asked John, then I spent probably 2 weeks to more less understand what is happenning. Now, there is version 7 of PTGui, automatic usually work well, however when there are problems users do not usually know what to do - like you. My general advice - try to understand PTGui and the optimizer, and I think the best thing to do is to use somebody's images. This is what I did, I worked on John's photos. Then now I wrote my own little tutorial to help others, here it is: lookdigital.eu/tutorial_ptgui.htm you can download my photos and you can download my PTGui file, when you manage to stitch this panorama perfectly you will be able to stitch any panorama, you will have to go through most things: CA corection on jpg (it is not easy), vignetting corection, T1 and T2 lines, corecting nadir and zenith my advice - DO ALL MANUALLY, do not use any plugins or any automatic features of PTGui good luck alert moderator
Forum: Galleries Thread: First 7.5mm results	Re: First 7.5mm Posted: 29 Jun 2007 at 16:40 GMT go to thread I don't know why it has so much flare, I have the same and the newer model, bohe of them behave the same, however it is possible to live with it, as I said, just take more photos so they overlap more, then you will need to correct it manually in ps on layers alert moderator
Forum: Galleries Thread: First 7.5mm results	Re: First 7.5mm results Posted: 29 Jun 2007 at 8:11 GMT go to thread Mark, the lens you have is one of the most valuable in the world when it comes to panoramas, it is maybe even sharper than the sigma f3,5, but it has a bit too much flare, you can overcome this by taking a more photos, I usualley take 7 or 8 photos, my hdr panoramas were taken with this lens: lookdigital.eu/hdr.htm alert moderator
Forum: Q & A Thread: how to tell ptgui to patch the zenith?	Re: how to tell ptgui to patch the zenith? Posted: 28 Jun 2007 at 18:53 GMT go to thread panocanarias is perfectly right, just move the zenith up - the will only be one proper possition, then move the zenith left or right to find best possition for it, then you will need to have layers and generate 2 panoramas one with photos with zenithe, econd - only zenith, then generate the squares with pano2qtvr for zenith only, keep the top square only, then open the proper pano and also generate the squares (cubes), then open both top cubes from both panos and import the cube from zenth to the cube from panorama and do the rest manually also I am not sure what lens you are using - but check your crop in PTGui - crop should be the circle right where the black part starts (longer lenses don't have black parts) alert moderator
Forum: Q & A Thread: PTGui - vertical FOV	Re: PTGui - vertical FOV Posted: 28 Jun 2007 at 7:50 GMT go to thread DorinDXN is quite right, I did similar thing, I had 78 images from 350D (the green forest lookdigital.eu/hri.htm ), first of all PTGui could cope with it, then photoshop couldn't cope with so many layers (each layer around 20MB in tiff format); I finally generated 2 panos, each with half of the layers, then correcvted the errors and flattened them in photoshop, then I opened 2 flat panos in photoshop and manually stitched them in photoshop alert moderator

Forum: Q & A Thread: Request for testing new DevalVR with full Hardware Acceleration	Re: Request for testing new DevalVR with full Hardware Acceleration Posted: 26 Jun 2007 at 20:10 GMT go to thread fiero, I didn't want to install any more plugins for a long time, but once I intalled DevalVR I think it is very very good work! I have Matrox Parhelia APVe (128MB) - all uyopur samples work generally well, the first one has the same errors like Oender discribed, the rest are quite nice and smooth, the IE window gets dark when I press the other pano in the 4th example, and I don't like when the toolbar (bottom left) disapears whn I click the photo to move it (3rd example) tested on IE alert moderator
Forum: Q & A Thread: 320 image pano, how to stitch?	Re: 320 image pano, how to stitch? Posted: 26 Jun 2007 at 19:55 GMT updated: 26 Jun 2007 at 19:56 GMT go to thread I am a bit surprised that the ocean is a problem, usually water or clouds are quite easy, anyway, check if you have any control points on those photos - none of the points is good, so just delete them (for the ocean only of course), then you can generate a pano and open it in photoshop and then just correct the errors using stamp tool - any thing you copy will be fine - it is the ocean, also you can generate a stitched pano and layers together and then just correct some errors the bottom line is that everything on the ocean had moved before you took another photo - so you do not have any good control points at all, sorry, in this case automatic setting will probably not work at all, if you want it good - DIY alert moderator
Forum: Q & A Thread: Stitching scenes with moving objects? Can it be done?	Re: Stitching scenes with moving objects? Can it be done? Posted: 24 Jun 2007 at 18:52 GMT go to thread ghiebert, sorry, any soft is not enough, whatever quality photos you will provide is just software, nothing more, a good panorama needs human judgement, if you want to make a pano any soft will do now I think, but if you want to do a good pano you need to learn how to do it, software like PTGui can provide you with psd file and all photos are put in layers, then you need to make them stitch properly using masks, otherwise you will always end up with a so so pano, one better, one worse - nothing more alert moderator
