I have taken numerous photos of one rose in particular whose color is very different when displayed on a monitor as compared to the real life rose. In this case both the monitor and camera are calibrated to 100% Adobe SRGB.
I have tried several camera raw programs and the results are only slightly different and nowhere enough to make the image color agree. And just for the record, the white balance and black point are fine. The leaves and buds look great, the back drop is spot on, but the rose looks reddish whereas the real rose is lavender.
First of all, it's important to know that digital cameras by and large do not 'see' (capture) colors as we humans see them. They suffer Metameric failure and do not follow the Luther Ives condition (more below). So don't expect that what you capture as essentially 'three grayscale channels of data' can mimic what you see. Cutting to the chase, you are in control of rendering this to colors you desire in a good raw converter. It may take selective color adjustments but none the less, you should have the tools in a good converter to produce a color (the rose itself and other stuff) as you desire and recall (not necessarily the actual measured color at the scene). That's what rendering images is all about!
White balance, which we often pursue with the "eyedropper," consists of a red/blue balance and a green/magenta balance (i.e., green v not green). As we have all experienced, a minute change in red/blue balance can change blue into green, or a rose into a violet.
A rose is either a woody perennial flowering plant of the genus Rosa (/ˈroʊzə/),[1] in the family Rosaceae (/roʊˈzeɪsiːˌiː/),[1] or the flower it bears. There are over three hundred species and tens of thousands of cultivars.[citation needed] They form a group of plants that can be erect shrubs, climbing, or trailing, with stems that are often armed with sharp prickles.[2] Their flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwestern Africa.[2] Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height.[2] Different species hybridize easily, and this has been used in the development of the wide range of garden roses.
The name rose comes from Latin rosa, which was perhaps borrowed from Oscan, from Greek ῥόδον rhódon (Aeolic βρόδον wródon), itself borrowed from Old Persian wrd- (wurdi), related to Avestan varəδa, Sogdian ward, Parthian wâr.[3][4]
The sharp growths along a rose stem, though commonly called "thorns", are technically prickles, outgrowths of the epidermis (the outer layer of tissue of the stem), unlike true thorns, which are modified stems. Rose prickles are typically sickle-shaped hooks, which aid the rose in hanging onto other vegetation when growing over it. Some species such as Rosa rugosa and Rosa pimpinellifolia have densely packed straight prickles, probably an adaptation to reduce browsing by animals, but also possibly an adaptation to trap wind-blown sand and so reduce erosion and protect their roots (both of these species grow naturally on coastal sand dunes). Despite the presence of prickles, roses are frequently browsed by deer. A few species of roses have only vestigial prickles that have no points.
The majority of ornamental roses are hybrids that were bred for their flowers. A few, mostly species roses are grown for attractive or scented foliage (such as Rosa glauca and Rosa rubiginosa), ornamental thorns (such as Rosa sericea) or for their showy fruit (such as Rosa moyesii).
Ornamental roses have been cultivated for millennia, with the earliest known cultivation known to date from at least 500 BC in Mediterranean countries, Persia, and China.[11] It is estimated that 30 to 35 thousand rose hybrids and cultivars have been bred and selected for garden use as flowering plants.[12] Most are double-flowered with many or all of the stamens having morphed into additional petals.
In the early 19th century the Empress Josephine of France patronized the development of rose breeding at her gardens at Malmaison. As long ago as 1840 a collection numbering over one thousand different cultivars, varieties and species was possible when a rosarium was planted by Loddiges nursery for Abney Park Cemetery, an early Victorian garden cemetery and arboretum in England.
In temperate climates, cut roses are often grown in greenhouses, and in warmer countries they may also be grown under cover in order to ensure that the flowers are not damaged by weather and that pest and disease control can be carried out effectively. Significant quantities are grown in some tropical countries, and these are shipped by air to markets across the world.[13]
Rose perfumes are made from rose oil (also called attar of roses), which is a mixture of volatile essential oils obtained by steam distilling the crushed petals of roses. An associated product is rose water which is used for cooking, cosmetics, medicine and religious practices. The production technique originated in Persia[14] and then spread through Arabia and India, and more recently into eastern Europe. In Bulgaria, Iran and Germany, damask roses (Rosa damascena 'Trigintipetala') are used. In other parts of the world Rosa centifolia is commonly used. The oil is transparent pale yellow or yellow-grey in colour. 'Rose Absolute' is solvent-extracted with hexane and produces a darker oil, dark yellow to orange in colour. The weight of oil extracted is about one three-thousandth to one six-thousandth of the weight of the flowers; for example, about two thousand flowers are required to produce one gram of oil.
The main constituents of attar of roses are the fragrant alcohols geraniol and L-citronellol and rose camphor, an odorless solid composed of alkanes, which separates from rose oil.[15] β-Damascenone is also a significant contributor to the scent.
Rose hips are high in vitamin C, are edible raw,[16] and occasionally made into jam, jelly, marmalade, and soup, or are brewed for tea. They are also pressed and filtered to make rose hip syrup. Rose hips are also used to produce rose hip seed oil, which is used in skin products and some makeup products.[17]
In France, there is much use of rose syrup, most commonly made from an extract of rose petals. In the Indian subcontinent, Rooh Afza, a concentrated squash made with roses, is popular, as are rose-flavoured frozen desserts such as ice cream and kulfi.[19][20]
The flower stems and young shoots are edible, as are the petals (sans the white or green bases).[16] The latter are usually used as flavouring or to add their scent to food.[21] Other minor uses include candied rose petals.[22]
The rose hip, usually from R. canina, is used as a minor source of vitamin C.[25] Diarrhodon (Gr διάρροδον, "compound of roses", from ῥόδων, "of roses"[26]) is a name given to various compounds in which red roses are an ingredient.
The long cultural history of the rose has led to it being used often as a symbol. In ancient Greece, the rose was closely associated with the goddess Aphrodite.[27][28] In the Iliad, Aphrodite protects the body of Hector using the "immortal oil of the rose"[29][27] and the archaic Greek lyric poet Ibycus praises a beautiful youth saying that Aphrodite nursed him "among rose blossoms".[30][27] The second-century AD Greek travel writer Pausanias associates the rose with the story of Adonis and states that the rose is red because Aphrodite wounded herself on one of its thorns and stained the flower red with her blood.[31][27] Book Eleven of the ancient Roman novel The Golden Ass by Apuleius contains a scene in which the goddess Isis, who is identified with Venus, instructs the main character, Lucius, who has been transformed into a donkey, to eat rose petals from a crown of roses worn by a priest as part of a religious procession in order to regain his humanity.[28] French writer René Rapin invented a myth in which a beautiful Corinthian queen named Rhodanthe ("she with rose flowers") was besieged inside a temple of Artemis by three ardent suitors who wished to worship her as a goddess; the god Apollo then transformed her into a rosebush.[32]
Following the Christianization of the Roman Empire, the rose became identified with the Virgin Mary. The colour of the rose and the number of roses received has symbolic representation.[33][34][28] The rose symbol eventually led to the creation of the rosary and other devotional prayers in Christianity.[35][28]
Ever since the 1400s, the Franciscans have had a Crown Rosary of the Seven Joys of the Blessed Virgin Mary.[28] In the 1400s and 1500s, the Carthusians promoted the idea of sacred mysteries associated with the rose symbol and rose gardens.[28] Albrecht Dürer's painting The Feast of the Rosary (1506) depicts the Virgin Mary distributing garlands of roses to her worshippers.[28]
Roses are a favored subject in art and appear in portraits, illustrations, on stamps, as ornaments or as architectural elements. The Luxembourg-born Belgian artist and botanist Pierre-Joseph Redouté is known for his detailed watercolours of flowers, particularly roses.
Other impressionists including Claude Monet, Paul Cézanne and Pierre-Auguste Renoir have paintings of roses among their works. In the 19th century, for example, artists associated the city of Trieste with a certain rare white rose, and this rose developed as the city's symbol. It was not until 2021 that the rose, which was believed to be extinct, was rediscovered there.[36]
