When applied to real photos, you need to add tiny amount of Blur to Flat Field layer to avoid high frequency noise. It makes field 100% flat and also removes all tiny color casts.įlat Field layer should be in Linear gamma, so if put Levels inside, set Auto Levels clip to 0% and adjust only white clipping point - final corrected image brightness will remain unchanged (Levels applied in Linear Gamma is same as applied Exposure). It works really perfect in Linear gamma and in 32 bit. So instead of another attempt to adjust my lightbox, i decide to test well known Flat Field Correction method. I tried many different custom-made light sources and light designs, but in best case scenario light is ok, but not perfect. Linear gamma needs additional color management setup, but allow more presice WB adjustments and more accurate color transformations.ĭue nature of diffused light combined with my rather wide angle 39 mm macro lens, seems it is near impossible to get perfectly uniform backlight. You can export to ProPhoto or ACES color space with L* TRC or with Linear gamma. Anyway, this is all too complex, so i just recommend to use Iridient Developer and export to TIFF, especially if you use Fujifilm cameras with X-Trans sensors. But it is possible add custom made input ICC profile to PhotoLine preferences so it will be used as default input profile for RAW images. PhotoLine use LibRaw to open RAW files, so formally you can open your camera scans directly in PhotoLine, but RAW workflow yet designed there in not too logical way (you can check my explanation and improvements for RAW workflow in PhotoLine here )Īnd also LibRaw camera profiles are far from perfect. Colors are more saturated and look about the same as colors from my custom made input profile made with calibrated IT8.7 Chart. They are very different from ACR, NLP and LibRaw/dcraw. I really like Input profiles provided by Iridient Developer. Note that Input Profiles are the most important thing in negative scanning. darktable negadoctor also works very well. NLP use custom made input profiles (probably based on modified LibRaw or ACR something so). So in most cases compression between 91-95 is match to PhotoShop "High" to "Very High" range.Īlways enable "High Quality" checkbox in JPEG settings.Ĭlick to expand.NLP formally use all the same tools, but they are arranged in different way and so not so easy to control in complicated situations. Also JPEG compression slider is non linear there. It allow way more higher and lower compression levels than Photoshop. Note that PhotoLine use different compression scale than Photoshop. "Web Export" always converts to sRGB and also you can preview JPEG compression. it is way simpler to use special "Web -> Web Export" dialog. Or you can simply open already exported 32 bit TIFF in PhotoLine and do the same convert.įor quick export to sRGB JPEG no need to merge layers and convert color space every time. So for print before export you need to merge all layer and and convert it to 16 bit depth in Image/Document attributes panel. Formally Photoshop itself can't use 32 bit images at all. It process 32 bit images with special HDR module in sRGB or with ACR module. Your problem is due Photoshop can't handle 32 bit images. Modern printers can output a lot of wide gamut colors. The trial period only lasts for 30 days.Click to expand.Do not downscale final image to sRGB for print.Therefore, if you want to work with all kinds of image files with a selection of very interesting tools, you only have to download PhotoLine. Advanced text distribution, allowing the inclusion of text within the objects without any need for them to be text boxes.Improve photographs with specific tools (light and shadow, color temperatures, noise correction, etc).The first thing that is noteworthy of PhotoLine is the possibility that it offers to process images without losing any information, working with masks that add elements to the drawings and images without modifying the images original data.Īmong the other noteworthy features of PhotoLine you will find: There are multiple drawing and photograph editing tools on the market, with Adobe Photoshop standing out over all the rest, but there are other more economic alternatives with nearly all the options offered by this great program, like PhotoLine.
