outdoors Posted May 2, 2015 Share Posted May 2, 2015 I am stunned and amazed that you managed to add this feature in a matter of days. And it is already a great start. I have now tried it and have some feedback to make it fully usable (as it is now it really can't be used). Leveladjustments A z-depth map will always render from 3D-software as a kind of black/white fog according to the scene total depth starting at the camera lense; therefor the levels does not fall exactly where you want them in order to give the correct focus to your object. This is why the user must be able to tweak to black/white threshold of the map, much like a levels filter. If this is not available, the focus of the blur will always be at the very edge of the camera and thus blurring everything. This is not something you would be able to easily tweak in a separate document so these controls are necessary. Focus plane The idea of a z-depth map is to provide depth info about the scene, but the user should then be able to pinpoint the focus at whatever depth he/she wants by moving a small marker to the desired location/gray level. Or this could be done with a slider. The range of the map is then recalculated so if the user wants focus in the middle, the map will blur both in front and the back. IE. the map will be recaclulated as black-to the white focuspoint- to black, according to the preexisting levels. Think of the z-map as focus steps with a looping gradiant instead. Edges It is very important that the edges of each focus step bleed/or don't bleed correctly into whatever is behind it. A black point on white background, will give you a halo of the point event though it is in full focus. In the opposite way, sharp mask edges can be seen at the highest levels of blur. This is of course the hardest part to get right due to the way blurring works. Tif crashes When trying this feature, the app will crash when loading 16 bit z-dept map in tif. rui_mac 1 Link to comment Share on other sites More sharing options...
Staff Andy Somerfield Posted May 3, 2015 Staff Share Posted May 3, 2015 Hi, Thanks - as you say, the feature went in quite late so I expect that some more is needed before it's finished. Hopefully the extras you list will be added before the next update :) If possible, can you send me the crashing tif to support@seriflabs.com? Thanks, Andy.

outdoors Posted May 3, 2015 Author Share Posted May 3, 2015 Done! It is in your mail box :) Looking forward to the next update. The field blur was a very nice addition BTW. Very practical until z-depth is resolved. billtils 1 Link to comment Share on other sites More sharing options...
